Detailed tour through a Boeing 747-400!

hello and my series of tours around aviation icons continues today with this qantas boeing 747-400 here at the haas aviation museum in album park just south of sydney now the 400 series was the first major upgrade and modernization of the 747 and in this video i'm going to take on a detailed tour of this aircraft showing you the quirks and features of this amazing piece of engineering so let's go and check it out i make videos about planes if you're into trip reports from flights around australia and the world and tours through significant aircraft in museums then please check out my channel and subscribe i'm also on instagram and facebook now i will be repeating some of what i said in my 747 200 classic tour although this video will be in a lot more detail and you can skip ahead by clicking on the time stamps an obvious question is why the upper deck was so narrow and didn't extend the full length of the aircraft like we see with the airbus a380 back when this aircraft was designed they were expecting that passengers would prefer supersonic flight in concord and boeing's own 2707 and the 747 would essentially just be carrying freight by having the flight deck up on top you could open up the whole nose section allowing easy access to large cargo in fact if you look closely you can see the line where this door will join the rest of the fuselage these two prongs here are the pitot tubes which measure air speed and there's multiple on the other side as well to act as redundancy in case one fails it's also interesting to see these humans near the forward landing gear as it highlights just how big the whole aircraft actually is this little circle here is the mac cooling valve now just above that and we'll explore this shortly is a whole array of potentially quite hot electrical equipment and the cooling air escapes here this small red antenna communicates with air traffic control and this reddit jaffa is the vhf antenna this small yellow antenna here and the one a few meters behind it is for the dme which stands for distance measuring equipment which is an older navigation device this works by sending a radio signal to a known ground station such as the destination airport which then sends one back allowing the distance to be calculated this door which comes labeled is the electronic equipment hatch and this red and white thing is called a mass drain this is where any liquid that is sent down the drain goes but because it's freezing at high altitudes the liquid has to be heated up before it's expelled hence why there's a warning that it's hot otherwise the liquid itself would freeze and then block the end of the tube these little squares here are the low range radar altimeters which as the name suggests works out the absolute distance above the ground and this long white object is the marker beacon which is a vhf beacon involved in ils landings open and on display is one of the three heat exchangers in the air conditioning unit the pressurized air is bled from the jet engines but it's obviously very hot so there are two vents here and one on the other side the draw in cold air that cools the air down before going into the cabin and then that cold air from the outside is then expelled down by these vents underneath now if there is a problem and the pressure builds too high these circular release valves will blow out and protect your ears amongst other things now speaking about engines this is the fifth engine pod if an engine breaks down at a distant port the airline can literally carry another one on another 747 this saves having to rent a large cargo plane to fly one out and speaking about the engines here's engine number two a rolls royce rb 211 which is an iconic turbo fan and used across many aircraft including the 757 767 l1011 tristar and even the tupolav tu-204 may recall from my 707 tour that these engines are considerably wider than the older turbo jets but it's mostly just air as you'll see when we look from the back these are high bypass engines which means that the majority of the air bypasses the hot core where the air will be compressed and ignited as well as the core itself producing thrust it also turns a big fan at the front which spins and acts as a massive propeller so essentially these are both jet and prop engines combining these designs increases efficiency and lower noises an f-22 fighter jet for comparison's sake just has a very large and powerful thirsty hot core well two of them in fact now if you look from the back you can see just how much of the engine is just space with the core in the middle and then you can see the fan in the distance which would be blowing air both into the core itself and around it we'll spin around and go and have a look at the main landing gear most aircraft including pretty large aircraft such as the triple 7 only have two main landing gears as does the 707 from longreach you can see now in contrast the 747's main landing gear is far more complex with 16 wheels that spread the weight over a larger area having said that it can still land if only two opposing landing gears are deployed as everything was over engineered just to be as safe as possible now what the camera really doesn't show is how massive the wheel well is and that piping is involved with the air conditioning now let's jump out to the end of the wings now these wing tips which were added with the 400 series may not look particularly large but they're actually 1.8 meters high and improve efficiency this pipe here is the valve to dump fuel and this vent is a knack out dact this and there's one on the other side allows air to escape when the fuel tanks are being filled on the ground and then during the flight it allows air to replace the fuel that has been burned on the forward or the leading edge of the wings are kruger flaps which work to increase lift at low speed they fold out from underneath as you can see in this on-board footage and on the trailing edge are the three-part slotted flaps which you can see now in this in-flight footage these increase the wings surface area and while they do look pretty flimsy they actually improve lift by up to 90 percent now these pods you're seeing behind the wings are not fuel tanks as some people suspect but rather simple aerodynamic covers for the flaps extension mechanisms they themselves are just metal linkages that wouldn't be particularly aerodynamic hence the smooth pod that covers them the actual wing fuel tanks are further within the wings themselves continuing our walk there is another antenna and another mast drain in earlier aircraft the mast itself would be pretty small but they found that things like coffee and coca-cola were leaving nasty skid marks along the aircraft's underside so they figured that they should release it a little further away from the aircraft's skin and behind this door is the storage these two air vents at the back are the outlet valves for cabin air now if we flip around and look from the behind you'll see the outlet for the auxiliary power unit this is actually another smaller jet engine that essentially runs the aircraft systems when the main engines are turned off such as when you're boarding the plane now here's one that has been removed from a 747 for you to have a look at the air is drawn in from the top and then it's expelled out the back if we take a step back and it's a little difficult because of the fence but with the 400 series they redesigned the horizontal stabilizers and inserted 12 000 liter fuel tanks providing an extra 650 kilometers of range you can do the math yourselves but those fuel figures sound pretty similar to my old xr8 now before we head inside for a detailed visit to the flight deck on the cabin let's climb up into the mec and the forward storage hold now everything i've done today including climbing up through this electronic equipment access hatch is open to the public in their platinum tours and i can't emphasize enough how much you have to come and visit and do this tour if you're an av geek my tour was run by a retired 747 pilot customer service manager and a licensed aircraft maintenance engineer who all worked for qantas and on this very aircraft and it was an awesome day up the ladder and immediately spinning around forward you've got electronics and the mechanism for the forward landing gear now here's a screenshot of the same position in a 747 200 and you'll notice that it's all pretty sparse and that red handle there is to manually lower the landing gear back in the 747 400 you'll see a lot more electronic equipment and they've removed their manual release because the reality is that if the hydraulics did fail they'll just open up the doors and gravity will pull the landing gear down spinning around and you'll see the main equipment systems all lined up the keto static system here connects through to the air data computers you've got generator control units through here bus control units so that controls the power going for the buses you've got the data management computers you've got the maintenance computer so these are the central maintenance computers three of them they compare information that comes in the three systems for the air data computer compares all that information as well and there's three for redundancy three for redundancy yeah flight control computers all the flight controls are controlled through this computer here stab trim flap control your damp [Music] controller let's continue around it to the forward luggage hold remember that at altitude the air pressure outside the plane is a lot less than inside most aircraft doors open inwards so that if there was a failure of the locks they don't blow out but obviously there's no room for that in the cargo compartment so the locking mechanism has to be extra sturdy and here it is in action those green oxygen cylinders are the emergency oxygen tanks for passengers you might recall cylinder number four exploding on qf-30 the 747 that was flying over the philippines a few years ago cabin pressure was lost they quickly descended to 10 000 feet so they could all breathe again and they diverted to manila without injuries those four tanks down the very end are for drinking water and behind that is the central fuel tank and then further behind that is the landing gear wheel well and then the aft storage hold spinning around we've got an air conditioning unit which was added for the museum display while both four and aft luggage holds are pressurized only the aft one is heated therefore important luggage such as animals will always go back there now let's make our way outside again but i thought it might be interesting to crawl a little way forward towards the nose you've got more electronic equipment in here and insulation and it was just an incredible experience to crawl around inside the innards of a boeing 747 especially when i had actually flown in this aircraft as a passenger a few times now that's the nose straight ahead so i'm fairly sure that i'm actually now further forward than the flight deck and being a hopeless millennial i figured that it might be the time to film a selfie although i didn't realize until afterwards that i'd actually forgotten how to wear a hat you will see a ladder here which you can use to crawl up into the forward passenger cabin where we'll go shortly and then down the hatch out underneath the aircraft by the way this aircraft itself is unique because back in 1989 it broke international records by flying non-stop from london to sydney it took 20 hours and nine minutes and it really pushed the limits of the aircraft in fact they used a target to take it out to the runway so that they could literally just turn it on and then immediately take off as to avoid using any unnecessary fuel then in 2015 it did a short 12-minute flight from sydney to the haas museum in albion park and his footage i captured from that incredible day the 400 series maintained at the stretched upper deck of the 300 series and for comparison's sake here's a 200 series from long reach with the shorter upper deck but a major change was with the electronics remember that the 747 was designed in the 1960s and while the airframe remained sturdy all the other systems were pretty old so they were upgraded as you'll really notice in the flight deck shortly by the way what's an iconic view looking back at the massive wing and engines let's take a left first and explore business class in the nose because of the nose curving inwards the passengers in seat 1a can actually see a little forward but what's also very cool is that they're actually sitting in front of the flight deck in fact the flight deck is actually above row three these business seats were the sky bed mark ones and they were a huge upgrade from the previous recliner lounges and almost went completely flat although at a bit of an angle there were amusing stories of people waking up having slid down the seat with their legs up against the chest okay that's a bit of an exaggeration but they're in business so we're allowed to tease them now underneath a mat is the access hatched down into the mec which by the way stands for main equipment center which is where we were just crawling through a few minutes ago this hatch is useful if the crew need to access any of the equipment during a flight we'll wander through the business cabin further and on the right is a galley although we'll explore that in more detail soon there's a few more rows of business class and then you've got these wider seats in premium economy we'll pull a right and then head up the iconic 747 stairs in earlier models they were spiral staircases although these more plain ones use up a lot less room upstairs and immediately on the right you've got this crew rest spot and at the back of the upper deck is a galley and then rows of business seats in earlier models the upper deck was just a first-class lounge although obviously the accountants decided that they could make more money by filling it with seats as i mentioned earlier a major upgrade included new electronics including a glass cockpit and they removed the flight engineer as their role essentially became computerized now if i freeze the view now you'll notice that there are a lot of large screens now let's contrast that with the 200 series where everything is analog by the way i do keep mentioning the 200 series and there is a tour through that aircraft on my channel on the left you've got the crew oxygen cylinders and hidden in there would have been the crash axe to help the crew fix any disagreements if they both wanted the same meal options above you is the crew escape hatch and there's the escape reels which you would use to help get you down from the escape hatch which is a good motivation for pilots to be good at pull-ups i'll temporarily hand over to my guide for the tour but as i said earlier it's really awesome having an actual pilot who flew this very aircraft sharing their experiences with me so i'll just sit over here yeah yeah yeah uh captain left seat first off to the right seat yeah now you got your uh primary flight display you're funny with the blue of the sky on the ground here we've got the nav display it's set up at the moment to go city down to melbourne as you work your way across you've got the standby attitude indicator you've got 150 minutes of emergency power if you get total instrument electric exponent you've got the engine instruments in the center there's the eye test and the center shows your engine instruments also we can select that's the upper eye cast we've got the lara eye cache shows us all these different modes which we can select from that you got your flight management computers that's where the jumbo stickers so you got the data entry on that one and that puts in your flight plan all your uh all your um navigational instrumentation requirements also the trust settings for takeoff over over there on the captain's side but that wasn't enough classic no yeah no this is all the new computers so you can fly the jumbo with two piles a certified captain first off that would be classic jumper had captain first option and an engineer ford engineer was on that panel what was on that panel is now all over here so the old engineers panel is actually all incorporated over here on this side you've got auxiliary power unit control electrical control that's engine one two three and four you've got the hydraulics yeah you come up here that's emergency lights you've got the uh fire engine fire switches to shut down the engines in case of a fire that's the auxiliary power unit we can actually um if we get a cargo fire we can discharge ford or off cargo with a um there's four bottles uh this uh the fire agent in this this aircraft but the extended range dumbo's had six bottoms okay you've got the start switches pull on those to start the engines if you want to dump fuel that's the select a or b and we push those on and open the nozzles at the end of the wing and start dumping fuel yep that's all your uh fuel control panel and down here's your uh anti-ice switches for all the engines in the case of anti-ice that's wing anti-ice you've got your wiper blades windows are always heated keep them pliable in flight so that's always on it on it's off at the moment but in flight they're always on and you come up here you've got your uh eventually located transmitter so they can find the aircraft and emergency it's activated on uh like an impact i think it's 20g yeah passenger oxygen switches are back up we depressurize as part of our emergency procedures we'll turn that on as we come into the emergency descent to back up the oxygen mask dropping in the cabin yep now you've got your damper up and upper and lower powered by the hydraulic systems helps keep stabilizing the aircraft against the normal flight therapeutic oxygen we can actually supply oxygen to each passenger row and the customer service manager often would request us to turn that on for additional oxygen if they weren't using bottles we can actually get that's your landing altitude but it's automatically set in the flight management computer it will automatically know what the landing altitude is and adjust the pressurization accordingly but we can manually set the landing altitude that's your isolation valves and the wing ducts left and right they're normally on so if a duct blows out there'll always be at least enough here the two air conditioning packs to keep your pressure off oh yeah yeah so that though yeah left and right manifold you've got your passenger temperatures we set it to about 80 which is on both sides is about 23 degrees centigrade so that's for the passenger and also the flight deck you've got a zone where you set it there's a problem with the packs you push that trim air is what comes out of your little uh little vents above your head that's an additional air you've got upper and lower recirculating uh air recirculation so it actually is designed as a fuel saving measure to recirculate the air and we don't uh lose as much we put half cargo heat on if we're carrying animals there's a the bulk hole and there's a switch in there we can actually turn on like the half coco if you stop the dogs from chilling down okay in flight so then they ended up with little cold dogs yeah we go high flavor hopefully the clear the uh the air we go high flow on the ground we'll get more cooling yeah that's your uh that's it your uh or your gas but sorry that's the gas portion so trimming is actually uh part of the air conditioning system gasps that's actually what comes out of your head okay humidifier yeah try and keep the air uh nice and moist but they're actually deactivated in the end because it wasn't worth the trouble with maintenance yeah one two and three so that your air conditioning packs would turn i press your eyes and condition there yeah uh there's your uh that's your uh oh sorry that's your isolation now sorry i have your tough info that's your isolation belt yeah that's your uh manual airflow velcro pressurization so we can yeah that's your isolation valves for that measure engine bleed lead air system so those valves normally have to be on to get bleed air out of the engines okay yeah there's your lighting your lights yeah so that's your uh beacon light when you navigate from uh modern aircraft tonight strobe lights at the end of the week ring lights logo lights what illuminates the tow and you can see the company logo oh yeah and there's your basically all your other lights landing nice and early and then down to the mode control panel here that's the uh each each panel controls the display on the nav and you can also set your your altimeter on that switch this is your barrow barometric elder chip which is you can set barrow there or we can set a radar altitude for uh low visibility uh landings and that's your uh map display that's the range on the map at 640 miles we turn on the radar normally by pushing the weather radar switch and you can bring up station wave point on your map display airport data position and also terrain is important the terrain switch is there uh and it displays a uh worldwide map of germain it will show you if you're getting too close to terrain basically in colours of green amber and uh but we also have a terrain warning system if you get too close it will actually go terrain terrain if you keep persisted with it it'll actually go walk pull up and get a sign then you've got to carry out a manual maneuver yeah so that's full thrust uh pitch to 20 degrees nose up while you're disconnecting the autopilot disconnecting the auto throttle menu manually push the the thrust levers all the way forward and pitching to 20 degrees now you have to clear this right yeah okay yeah and that's your uh airspeed indicator we sit uh on whatever airspeed we want to fly that's the this is the control panel for the auto part we latch up that's illness lateral navigation vertical navigation uh heading you can see usually set for that was set up for sydney runway one situated and the first uh expected initial altitude and then once we get onto air traffic control departure control i'll probably change that air speed that's an initial air speed just for uh what we call our v2 spin and then as we as as we accelerate the qualifying say engage the auto pod or the other port will actually set the newest speed as you climb out and usually set to 250 knots below 10 000 feet and then once you run once you once you're uh above that you can accelerate to your normal performance [Music] we've got other controls and you've got vertical speed switch we can hit altitude hold the aircraft will try and help level off and altitude you're already out we've got localizer for this approach [Music] and this this panel here controls what's on the lower display all right and that counts the same as the other side yeah all right so in the eye cast uh you can bring up fuel display if i push fuel i know this is going to work you can actually see what's in the tanks at the moment with zero uh and uh when it's it's fueled up we'll put on the boost pumps to coincide with what fuel is in the tanks after that we went through a few engine starts takeoffs and engine fire checklist which was incredible fun and the most realistic experience before getting into an actual airline simulator it was an incredible aviation nerd experience to sit in the captain's chair of a boeing 747 and push all four throttles forward all while picturing this actual footage i captured a few years ago flying this very plane out of sydney airport [Music] i'll mention this little device here as it's actually the steering wheel and this sitting here where the flight engineer used to be shows how old this aircraft actually is it's a disk drive for those old three and a half inch discs that i saw in primary school and they were used to update some software on the aircraft now considering when next to a massive aircraft hangar this view shows just how hard the 747 actually is now let's head back down the stairs and join a retired qantas customer service manager for the rest of the tour now if there was a fire in the lower levels obviously the smoke would rise and fill the flight deck so here on the left is an air tight cover that they would bring across and block the smoke from entering we'll head down the stairs and spin around underneath them behind this door is an elevator which can lift a trolley up to the upper decks in the 200 series they would also go down as there was another galley in the forward cargo hold and directly under the stairs is the customer service manager station in here they could control the in-flight entertainment announcements safety videos lighting call bells and communicate with other staff on the other side is more equipment for the mill service there's the water boiler and the coffee machine where freshly ground coffee or tea could be put in there next up there's more storage space and a heated compartment and then there's the ovens they're electrically heated conduction ovens where you could fit 36 economy meals although this galley was for business improving economy but before they cooked they kept it fresh in this chilled section now if you look down inside here you'll see two squares now if you pull out one of the trolleys you'll see that there's two similarly sized square vents so when the trolley is pushed in and against those it opens up a valve so cold air flows directly through the vent and into the trolley keeping everything cold and fresh and to create more workspace there were these drop down benches everywhere now let's continue walking back through premium economy you'll notice that the seats here are still pretty wide although they don't fold flat or angle flat like the ones in business and here we are entering the economy cabin where obviously the seats are smaller on the left here is a private crew rest area and i'll show you the bunk beds down the back shortly oh yeah i saw it there was a big wider chair in there there's a collection of four toilets here but just swinging back around is the storage area for the defibrillator and where the flexi cuffs were kept now they're legally allowed to arrest and handcuff passengers who were up to mischief although fortunately that very rarely happens now this footage really highlights just how wide the 747 was remember that it replaced the 707 which was only as wide as a narrowbody 737 which we see zipping around at domestic routes today you can really understand why something this big was just mind-blowing when it was introduced here we are in the rear galley used for economy class passengers this is the rear galley up top are more storage spots and in the middle are more ovens and then below that are the children carts on the other side is more of the same equipment as you have to remember that they had 270 passengers in economy to feed you've got the bun warmers which interestingly inside is now graffitied with a whole lot of amusing messages from the crew one said may the beautiful illawarra sun shine down on the flying kangaroo for years to come and quite amusingly another one said ojay back to rescuing more a380s in 2015. through there is a hole to look into the next station and another oven next up is the beverage center oh okay yeah this was one beverage because [Music] yep this this is really cool i quite like this idea if you've got a camera there so there's like two atlas boxes [Music] and that last box right down the end there yeah oh okay you smell yeah there we go and again [Music] um [Music] and these are all hot uh these are water boilers yep and these are going coffee makers [Music] and here's the eye spin which is what it sounds like and now moving on through the final cabin towards the rear of the aircraft you've got the flight attendant seat and behind that is a storage cupboard and moving further along are a few more toilets there's also a self-serve drink fountain moving around the other side there is another two toilets and the crew rest area which includes a number of bunk beds they'll all come with their own light air vent and emergency oxygen tank now these two orange things are the black boxes or the flight recorder there's the voice recorder on the left and the flight data recorder is on the right and then those little cylinders there are the underwater beacons that will emit an ultrasonic ping for 30 days from the depth of up to 6 kilometers there's also an emergency escape door where the crew can slide the bunk bed and then climb through that square hatch there they'll then drop down right next to the bathrooms downstairs straight ahead is a door into the aft pressure bulkhead which was interesting to see and then we're heading back down the stairs and have a quick squeeze at the toilet now let's make our way out of the aircraft and pass some of the stuff all of the members and guides here are volunteers and many have worked in the aviation industry and have an incredible wealth of aviation knowledge and check out this view as we step off this planet with the iconic red flying kangaroo tail and then we spin around and there you'll see the boeing 747 400 badge which i have no doubt will go down as an iconic site in aviation while this aircraft was the first of the 400 series flying for qantas i was on board the last 747 400 er vh oscar echo juliet on the last ever commercial qantas 747 flight in canberra last year and my video from that fight is on my channel in fact his footage i captured of that very same aircraft living australia for the last time where she overflew this aircraft here at hars the haas aviation museum is located at album park just south of sydney and has a huge range of aircraft on display including this 747 a super constellation f-111 camera bombers dc3 and even a soviet mig it's definitely worth visiting but just make sure you book ahead for the full platinum 747 tour as those spots do go fast and if you're lucky you may even see some of the fleet flying a huge thanks to the staff here for letting me film this aircraft and if you're into aviation then please give the video a thumbs up and check out my channel for many more similar videos thanks for watching
