CJ4 Systems and Avionics Explained - Working Title Mod - FS2020

this is a cj4 and this video is going to help give you a better overview of the airplane its systems and avionics and in real life i am a corporate pilot with over 7000 hours i don't fly this airplane but i fly an airplane with the exact same avionics and fms in it but i also use the help of a friend who's also a pilot and also a mechanic on a cj4 the cj4 has a maximum ramp weight of 17 230 pounds the aircraft is powered by two williams fj44-4a turbofan engines each producing 3621 pounds of thrust the aircraft is also pressurized and it has a ceiling of 45 000 feet and a range of just under 2 000 nautical miles the cj4's maximum speed is 451 knots true airspeed at 31 000 feet it normally has a two pilot crew but single pilot authorization is approved in the united states cj4 is also approved for day and night vfr and ifr operations and flights into known icing conditions and that's all good news for the nine passengers that can ride in the back of the airplane because they can go where they want when they want most of the time the cj4 is equipped with the collins proline 21 avionics and if you're wondering this is the working title mod the first item we'll cover is the display control panel there's one on each side and each panel controls its respective side with the exception of one button the first button we'll get to is the nav button this changes the navigation source between vor and fms one time you would use this is when you're doing a missed approach from an ils and you have to go back to pink needles to fly the route in the fms you can also at any time rotate the select knob and you can change from vr1 to vor2 and then press nav and then use whatever you selected down here next is the pfd menu or primary flight display menu and this changes items on the pilot side pfd the top section under format allows you to have three choices compass rose arc or present position rotate the knob to the selection you want and then push that same knob to make the selection under the controls section you can change your navigation source but whatever you change it to here it becomes the active navigation source you don't need to press nav at the top to switch it it changes immediately so in this position it's vor2 the screen will go away and you'll see vor2 is the active navigation source right there the next selection under controls is range right now it's set on 10 miles the total range is 10 miles whatever this distance says the inner circle is half of that total distance and a side note there is a better and easier way to adjust the range nobody really comes in here to adjust it at least i hope they don't because there's a really easy way to do it and i'll show you that in just a minute bearing source will bring up a bearing pointer or a second bearing pointer if selected the bearing pointer will point at the fms waypoint a vor or it will be an adf needle which will point to an ndb on the ground and to see what that looks like we have to tune a vor i'm tuning 116.3 now when we look back up you can see the blue needle pointing towards brickyard vor it is possible to put two bearing pointers on the screen at once we can tune in another vor put it in f2 and once the signal is received you can now see two bearing pointers the blue needle is vor1 the white needle under bearing pointer two is vor2 these needles will stay up until we go to the off position and select it then they will go away the next selection under controls is configuration and this is where we go to change our altimeter from inches to hectopascals with a selection like this one there's nothing to actually select you just highlight the item you want and then rotate the inner knob to get what you want and it stays there next is to put your altimeter in meters i changed it i could not actually get this to change i don't think it changes at all in flight sim 2020 in any airplane yet next is the presentation of the flight director we have a choice between v bar or cross pointer with the v bar you fly into it with a cross pointer you turn the airplane left or right or pitch up or down until the needles are centered and the last item under configuration is angle of attack display you can leave it on so it's continuously on or leave it in auto in auto it comes on when flaps reach 35 and the last item is refs here we can set takeoff v speeds and landing v speeds and these are the only thing on this panel that will set on the pilot side pfd and the copilot's pfd but if you set takeoff and landing speeds in the fms that will send them to both pfds and you don't have to go into this menu at all and also we can set minimums for an approach based on decision height or we can set barrow for an mda or decision altitude for example setting minimums on a category 1 ils approach and this is what will make the audible call out minimums when doing an approach so if you set barrel it's going to look at your altimeter if you set radar altimeter it will look at your radar altimeter here next is the escape button think of this as a back button if you're in a sub menu it'll go back to the main menu if you're in the main menu it'll take the menu box off the screen next we have an et or elapsed time button for example you're doing an instrument approach that does not have a missed approach point identified by distance so you have to use time this is the button you would press and you can see the time down here press it once to bring the time up and start it press it a second time to stop the time next is the format button this is simply an easy way to change between rows arc and the present position map and we just saw each one of those if we go back to the pfd menu you can see them under format right there they do the same thing that's just one more way of switching the format and like we said earlier we can press the escape button to cancel that menu next is the terrain and weather button the first press overlays terrain the second press will overlay the aircraft's weather radar and when weather radar is active you get this little blue line moving from left to right and that shows the approximate direction that your weather radar is pointed at and it will sweep left to right and in flight sim 2020 when you select radar or terrain it shows up on both pfds to turn off terrain and weather press the terrain weather button again and the indications will both turn white next is the tcas traffic overlay button this will show other air traffic on the pfd fortunately the radar menu toss menu and ccp menu do not work however the barrel knob does work set the local altimeter with it you can also press it to get 2992 for transition altitude we also have the tilt and range knob the outer knob is tilt it does not work the inner knob is range it does work and this is the easy way to adjust the range on the pfd and mfd next we have the electrical panel right now the battery is on the generators are on so the generators are charging the battery we can set the generator to off when this happens the generator is still producing power it's just not letting that power go out to the rest of the aircraft and you would use the reset position if the generator is not producing any voltage then you would select the reset position to try to reset the generator to get it to come back online chances are after it was taken offline by itself okay it won't do it by itself a little thing called a generator control unit will do it we also have the standby flight display that's over here above the landing gear lever you can see that turning off and on and that's a backup if all the screens go out and we lose elect total electrical power and standby flight displays normally have their own battery pack that will last approximately three hours some more some less with avionics turned on we have this with the avionics turned off we get this there's also a dispatch position the dispatch button will also power on the fms that allows the fms to be set up with your route departure arrival take off lane and performance etc and this enables you to set all that up without using all the avionics and running the battery down and this position is used when you come into a cold dark airplane and when you don't have a power cart moving down to the next section is the tilt panel it's a panel and it's tilted very clever name the first buttons we can actually manipulate are the fuel boost manual buttons that turns on an electric boost pump in the left tank or the right tank and if we need to turn them on manually this is where we do it you might turn them on for a low fuel quantity and when these pumps come on we also get a cast message more on cast messages later next is pilot fan this increases or decreases the speed of the fan for the pilot there's also one on the co-pilot side climate control we have off normal or compressor on normal will adjust the temperature based on where the pilot sets it and no matter what the compressor will not turn on unless the compressor on selection is chosen and this can also be used on the ground with a power cart plugged in to help cool the airplane next we have ignition these buttons will allow us to turn the igniters on for the left or right engine manually and they would be turned on when flying through heavy rain or turbulence next is the cabin pressure dump switch it has a red guard for a reason it's not advisable to press it unless it's an emergency when you press the dump button that opens a valve lets all the air out of the airplane and will blow all the smoke out of the airplane if there's smoke in the airplane as well if you can tell by now i'm only covering the switches that actually work in flightsim 2020. i wish they all did but they don't the cj4 also has a fuel transfer switch you can see right now the fuel is transferring from the right tank to the left tank this is sped up but it does transfer at approximately 1000 pounds per hour and this would most likely be used when you have a fuel imbalance this comes on at 100 pounds difference between the left or right tank next is cockpit temperature this sets the temperature in the cockpit the cockpit temperature is obviously on this side the cabin temperature is on the co-pilot's tilt panel the source knob is for pressurization the off position does not allow any incoming air to come in to pressurize the airplane selecting left will stop air coming in from the right engine selecting right will stop air coming in from the left engine normal will use both and fresh air will just use ram air coming in from outside but that will not pressurize the airplane either next we have ice protection these top two buttons are wing and engine anti-ice and the bottom two buttons are engine only anti-ice next we have pitot static heat these heat the pitot tubes and the static ports electrically and last of all we have a wing light and this is light that just shines on the wing and helps to see ice at night time this is what wing and engine anti-ice heats this would be the right selection and if you select the left button obviously you're going to get the other side and if you select just engine any ice you get just the engine inlets but if you're flying into icing conditions turn them all on use anti-ice before entering icing conditions use de-icing once you have ice on the airplane in the pitot static heat that heats the static ports on the side of the airplane and also the pitot tubes down here under the nose in the pitot static heat has a two minute time limitation for use on the ground and when you select the wing light on the ice panel this is what it looks like next we have the cursor control panel this mostly controls items on the mfd or multi-function display we have an upper and a lower portion the upper menu controls this section here it allows us to turn it off to choose fms text checklist passenger briefing or bring up the systems page just rotate the knob to select what you want then press the knob so here passenger brief and you can select each phase of flight and then press the knob again and it will play that briefing you won't hear it on here i have the sound turned down on the game on the editing software but when you do it on your flight simulator you'll hear it in the back of the airplane and let me correct that you'll hear it coming from the back of the airplane also in the upper menu we have a systems page this would allow you to bring the systems up and monitor systems in this position there's a systems button that will put it in a different place in the lower menu you can change between arc present position and the plan page is pretty much the exact same way on the pfd the only difference you use in this menu down here and it's only going to change what you select on the mfd so one neat feature on this you may not know about on lower menu if you select plan and then you have a route entered into the fms which i just put one in here from the departure point to terre haute to springfield illinois you can go down to the fms and select mfd advanced and then once it's selected you have previous and next waypoint if you hit next waypoint the mfd will move along from waypoint to waypoint and you can check your route you can check it in the fms but you can also check it this way and it gives you a pictorial view of your route so really what the lower menu is doing is allowing you to select what format you want on the mfd and it will also let you select symbols to put on the mfd as well so to do that we rotate the knob down to map symbols push it to select it then we have a choice between air spaces airways nav aids airports intersections i personally leave all these off it makes the map on the mfd a jumbled mess if you're wondering exactly what a jumbled mess is it's that right there so another cool thing you can do with these you can select what you want on the upper menu and select what you like on the lower menu and once you've got the mfd set up the way that you like it you can press memory one two or three you can press and hold it and it will keep the screen in that position for that memory button another thing you can do is press upper menu and under format select off and it will expand your engine instruments it will give you a little bit more detail and some gauges on oil pressure and oil temperature that you did not have before so you might decide you like the screen you hold down memory three or any of them i just chose three in this one and that saves it now i can select memory one memory two when i push memory three it goes back to the expanded engine and map page and so far when i've done this it has saved it when i close the flight simulator and come back in my page i want is still there and the escape button does the same thing on the other menu that we saw above pfd and if we want to bring up terrain or weather when we press the terrain weather button it will only bring it up on the mfd with this button the chart button doesn't work on flight sim 2020 it just brings up approach plates the cast page button cast is crew alerting system if you have cast messages on the mfd more than the amount that will display you can cycle through to the next page and see all the cast messages the engine button brings up the engine gauges in real life you press that button you get the expanded engine gauges or the small engine gauges this one if you press it they go away and then the terrain weather and traffic display they do the exact same thing as we saw on the previous menu above the pfd then we press the systems button that brings up the systems for electrical the battery oxygen hydraulic and fuel information then we also have a next page right there which shows trim information by pressing the checklist button in the upper menu you can bring up a checklist for each phase of flight use the outer knob to select the checklist push the select button to check each item or to select the appropriate checklist and once you've got the appropriate checklist you can just press the select button as i did and check off each item and the last button is the passenger briefing button which we already talked about a little bit so we'll skip that and move on to interior and exterior lighting here on the center pedestal you have the outer knob and an inner knob one controls the brightness of the pfd one controls the brightness of the mfd as you can see there and the center knob here controls the brightness of the back lighting on the panel and the knob on the right adjusts the brightness on the mfd and pfd the same as it did on the pilot side for exterior lighting we have a beacon press the button the red light flashes on the tail next is the navigation light we have a green light on the right wingtip and a red light on the left wing tip you'll probably notice there's no white nav light on the tail there should be i'm guessing but for some reason there's not and here's our strobe lights they flash on each wing tip next is the taxi lights they shine from underneath the fuselage and from the same location we have the landing lights when we press the landing light button like this the taxi lights turn off you can't run them both at the same time it's one or the other and you can see the landing lights are much brighter and also a much wider beam and here's a comparison landing lights and taxi lights and from underneath the horizontal stabilizer we have two lights shining down on the tail called logo lights the seat belt sign illuminates the seat belt sign in the cabin of the airplane but the safety light will turn on the emergency exit and main cabin entrance lights last of all we have pulse lights the pulse lights are just the landing lights but they flash and they're generally used below ten thousand feet and we also have a bright dem button on the fms and it actually works and next we have the speed brakes the speed brakes can be used between zero and one hundred percent for flight you have these two speed brake panels on each wing and this is what they look like when they're fully extended at one hundred percent right there you have a panel on the top and bottom of each wing but we also have a ground spoilers extend position and that opens up three more panels on each side to destroy lift and help the airplane stop faster and to the right of the throttle we have the flap lever flaps 15 can be extended up to 200 knots indicated airspeed and as we look at the airplane from the outside this is what flaps 15 looks like full flaps equates to 35 degrees of flap they can be deployed up to 160 knots indicated airspeed next we have aileron trim we can go full to the right and it has one trim tab only on the right aileron and that is full right aileron trim right there and if we go full left aileron trim we can see that it does the exact opposite and that actually took forever when i did that that's sped up like 10 times so it's actually very very slow and next we have rudder trim goes to 16 degrees either side and you can see the trim tab there on the tail and last of all we have elevator trim and you can see that moves trim tabs on each side of the elevator up and down and on the overhead panel there's also three floodlights you can move each rheostat clockwise to increase the brightness and when they are rotated to their full bright position they look like this in the daytime you can tell that they're on and here's the same lights in the night time so earlier we talked about fedex or full authority digital engine control simply put fedex is a babysitter for the engine the fedex computer gets weather information from around the airplane for temperature pressure and computes what the maximum power is under those conditions to illustrate that you can see the n1 fan speed changing the itt is changing based on the temperature moving the fedex makes takeoff climb and cruise much easier the pilot just puts the throttle in each detent and the engine will put out the maximum power for each phase of flight the cj4 also has two maximum indicated air speeds one below 000 and one above 8 000. below 8 000 feet it's 260 knots above 8 000 feet which we're almost at you'll see the air speed tape flip up to 305 indicated nuts and that is a thing in almost every citation i would say every citation i've ever flown and i actually had this question asked to me by a mechanic why it did that they were seeing if i knew it they said take a few days to think about it so instead of doing that i emailed an engineer at cessna and found the answer and the reason they gave me that the speed changes at 8 000 feet is because the faa says birds don't fly above 8 000 feet so above 8 000 feet you can go faster there shouldn't be any birds there below 8 000 feet if you were to hit a bird at that higher indicated airspeed it could shatter the windshield and at approximately 28 000 feet the air speed switches over to where we use mach indicated speed versus indicated airspeed and for mach the maximum speed is mach .77 and that's about it for the speeds as far as operational speeds everything is 200 knots first not to flap gear retraction gear extension and operating with the gear down 200 knots maximum indicated airspeed and to go beyond 15 degrees of flap you have to be at or below 160 knots and right there we're below 200 knots we can cycle the gear down we get three red meaning the gears unsafe and the gear is safe and fully down when we have three green another very cool feature about the cj4 it has electrically heated windshields and side windows there's an alternator in each engine that powers the window heat so if the engine is running the window has heat it won't fog up and it won't ice up so these front four windows are heated and there are no controls accessible to the pilot to operate them earlier we talked about cast messages or crew alert system messages you'll usually see three different colors of cast messages red means you need to do something right now amber or yellow means you need to do something soon or a white message means you've done something and it's a normal message is a status message the red master warning will cancel red items and the amber or yellow master caution will cancel yellow cast messages and when i say cancel that means they stop flashing red messages will always appear on top followed by amber followed by white messages they're listed in order of importance quickly i'm going to go over engine starting but i did miss one thing that i just now realized on the battery switch we have the battery on position in the up position and we also can move the battery switch down to aimer or emergency if you lose all electrical power and the battery switches in the on position and everything's running the battery should last at least 10 minutes but with that switch in eamer or emergency less stuff runs then the battery should last for approximately 30 minutes when starting the engine we press the start button down here on the bottom of the pedestal wait for 20 n2 when we get 20 into press the run button at that point the ignition will come on you'll see the three green letters right there ign for ignition that's the left ignition then you'll also see itt start to rise see that right there see that yellow indicator on the itc on the left side go up that's another thing that fedex does it knows the difference between when the engines are off start take off all that it knows the differences and it will know the limits and during the engine start the itt is one of the most important gauges you can watch to make sure that the engine starts correctly in the middle you have the starter disengage button this would be used if you want to stop the start immediately or if the starter doesn't disengage after engine start and to shut the engine off the same button we pressed to start at the run button we would press that again and that would shut the engine off and for the final segment of the video i'm going to show you some operational tips for a climb speed 230 knots indicated airspeed works really well you can use 250 but 230 works and you use 230 knots until you get to mach 0.62 you'll also notice in the climb as we held an indicated airspeed our mach speed increased once you reach mach .62 push the center button on this speed knob to switch over to mock so flight level change will now hold mach speed instead of indicated airspeed and as we climbed our fuel flow also dropped significantly once we live off i'll let the airplane accelerate then i'm looking for a true air speed i'm going to use about 420 knots once that's achieved i'll adjust the power to maintain 420 knots and if you've ever wondered what this little pink line is on the airspeed that's the airspeed trend indicator that's approximately where your airspeed is going to be in about 10 seconds over on the mfd we have rat and sat room air temperature is basically the temperature the airplane skin feels if you speed up this will heat up if you slow down it will cool down static air temperature is the temperature of the ambient air around the airplane so that's the actual air temperature then international standard atmosphere or isa it's iso plus one so it's one degree above standard temperature at this altitude and as i said increases of your climb performance will decrease however when cruising at a given indicated airspeed if isa increases your true airspeed will increase so at that same airspeed if it was iso minus 5 your true airspeed would be slower and another helpful trick is knowing what power settings will give certain air speeds so if you're playing vatsim you descend down to 10 000 feet you need to go to 250 knots if atc says slow to 200 knots it's good to know exactly where to set the throttle to do that and here's a way to do it and the trick is to use fuel flow so i've adjusted my power to maintain 250 knots then i looked over at fuel flow so we can see fuel flow is 464. we'll just say 470 pounds per hour per side so if we set the fuel flow to 470 that should give us 250 knots indicated airspeed for pretty much any altitude and here's the same setup at 15 000 feet power is set at 465 pounds per hour and the air speed is slowly decreasing to 250 knots and back down at 6000 feet this is why you don't use n1 to do this at 6 000 feet we had 54 in one to get 250 knots right now we're doing 253 and we have 63 in one here we are at flyable three zero zero got 470 pounds per hour per side and you can see even at 30 000 feet that same fuel setting has given us approximately 250 knots and at this altitude it's actually going to take a little bit more it actually slowed down just a little bit but it might take 480 490 pounds per hour to get 250 but you get the point fuel flow will give you an indicated air speed you can also see up here where almost 75 percent in one versus a 15 000 we're at 63 percent to get 250 and if you're assigned a speed of 200 knots you can go to 300 pounds per hour and that will give you 200 knots indicated airspeed so that's it for this video i hope you found it useful hope you found it helpful i do have plans for more videos using the cj4 working title mod i have a few ideas and videos i want to make and also thank you to the working titlemod group who makes this this is absolutely fantastic and one of the best additions to microsoft flight simulator 2020. and as far as functionality this is as close as you can get to the real thing in this simulator right now and if you want to know more on how to operate the fms i do have a video on loading the fms up and i also have a video on working the autopilot and the flight guidance panel and i will link both of those in the description and last of all thank you to ian one of my subscribers for making the corporate pilot dad paint scheme for the cj4 and if you enjoy this type of video i also have a video like this that explains all the buttons and some of the systems on the tbm 930 i also do the exact same thing with the cessna 152
