Understanding The Dangers of Thunderstorms - MzeroA Flight Training

hey everyone Jason Schappert here of m0 a.com and we're launching a new series now this month we're diving into and talking about aviation weather it's kind of that time of year summer is coming summer thunderstorms are coming here we're gonna be dealing with this more and more so today we're talking about the thunderstorm flying and I want to start with a story about an hour before takeoff the pilot obtained an updated weather briefing which included a discussion about thunderstorm activity along the route of flight about two hours thirty minutes after takeoff the pilot was deviated around thunderstorm activity when the airplane disappeared from radar a witness near the accident heard the aircraft revving up and down and then a muffled pop and in silence before scene debris falling from the sky well above the treeline examination of the airplane revealed that it experienced an in-flight breakup however no evidence of a mechanical malfunction was identified weather radar images indicated the airplane entered a developing area of moderate to heavy intensity echoes consistent with a convective cell or thunderstorm the pilot advised air-traffic control he was receiving weather information through a portable GPS receiver with a weather subscription service there were no published convective segments at the time it's interesting to me or center weather advisories for thunderstorms current at the time of the accident for the area encompassing the accident site the pilot received his airplane multi-engine rating on may 13th 2006 as of June 18th 2006 the powd have accumulated 1720 hours of total flight experience which included 32 hours and multi-engine airplanes 26 accumulated in the accident airplane in addition the pilot had logged about 140 hours and 68 hours of actual and simulated instrument time respectively except for 0.4 hours of simulated flight time logged er is multi-engine checkride the pilot had not logged any additional instrument flight experience in multi-engine airplanes review of the airplanes ground speed revealed the ground speed remained between 190 and 200 miles per hour during most of the crews portion of the flight and approximately 12 47 the airplane gained 60 miles per hour and ground speed over the course of the next 35 seconds the airplane descended 1,200 feet during this timeframe for an average descent rate of approximately 2,100 feet per minute the airplanes ground speed stabilized for the next eight seconds while the airplane to send it an average rate of 9000 feet per minute at 12:48 the airplanes ground speed began increasing again to 471 miles per hour the last required GPS target was at 12:48 and altitude of 4,000 123 feet with an average descent rate of 6,000 feet per minute the NTSB is probable cause the pilots invert an encounter with a thunderstorm which result in loss of control and a subsequent in-flight breakup I hate talking about accidents especially ones like this but I chose this NTSB report to illustrate there were no convective segments at the time you saw the weather radar you might be thinking wow I have screenshots of me on flight aware and I've been near storms that look just like this and this is why it's so important to understand thunderstorms and how a thunderstorms actually develop as well you see you need to understand not just for a private pilot checkride or an instrument pilot checkride we need to know the ingredients that make up a thunderstorm what do we need we need unstable air we need an uplifting action and then we need excess moisture this is why summer storms are so prevalent it's unstable we get the uplifting action the uneven heating of the Earth's surface and then the dissipation of that heat and then it's humid just about wherever you go unless you're flying out in Arizona per se deal with that humidity the humidity is excess moisture in the air so in a case like Florida where we fly this is how we get those afternoon thunderstorms now our thunderstorms go through three stages they are the cumulus stage which is depicted as the building phase this is the nasty updrafts and can often lead to some down drafts in these in these towering cumulus Nimbus clouds as well in our accident it looks like he may have encountered a thunderstorm that was in the cumulus stage building albeit very rapidly though and possibly some microburst associated with that as well we then enter into the mature stage at the start of rainfall the moment rain falls the mature stage and thunderstorm has begun and then lastly the dissipating stage this is where the thunderstorm begins to rain itself out have you ever been caught in a storm where it's raining raining and all of a sudden everything breaks loose the rain increases you know tenfold the size of the droplets double that's the dissipated stage it can no longer hold up moisture up and just it's dissipating that storm all the way out what does the FAA have to say about thunderstorm flying for this we can actually go to the aim where I'm going to call them thunderstorm rules we know that in the aim the aim is just helpful suggestions but if we all acted like they are rules we'd be safer smarter pilots as well so i'ma call them thunderstorm rules even though they come from the aim never go closer than five miles to any visible storm cloud with an overhanging area and strongly consider increasing that distance to 20 miles or more you can encounter hail and violent turbulence anywhere within 20 miles of very strong thunderstorms our next rule and some of these come from the aim some of these come from advisory circulars as well on thunderstorm flying do not attempt flight beneath thunderstorms even when visibility is good because of the destructive potential of sheer turbulence in these areas think back to the story we opened with here can you see how this rule applies at the first sign of turbulence reduce air speed immediately to the manufacturers recommended air speed for turbulent air penetration for a specific gross weight that could be your maneuvering speed or VA remember that's why they specify a gross weight because maneuver and speed changes with weight our next rule if the aircraft inadvertently penetrates a thunderstorm maintain straight and level a straight and level attitude on a heading that will take you through the storm in the shortest time so often we think oh I'll make the hundred and eighty degree turn I'll get back out of here and that can work VFR and IMC into a nice stable Stratus layer but if you start getting nasty updrafts and downdrafts the best thing you can do is straight and level and hold that don't don't worry about much anything else though or about your altitude keep within range within reason but you try to make a turn out of there you could really be testing the structural integrity of your aircraft obviously we don't want to end up in that situation that's why I want to leave you with this never let compulsion take the place of good judgment you never have to be anywhere in aviation if you do you can have a back-up plan to airline to drive whatever it may be but don't let compulsion the need to be there take the place of good judgment this is why we have the commercial pilot certificate people always say why can't private pilot's fly for compensation or higher because when you start to fly for compensation or higher it adds such a unique pressure the pressure to you know I got to pay the bills the pressure to the boss is asking me to be there I'm flying this VIP whatever it is they're expecting me to be there that's why we have the commercial pilot certificate just to alleviate some that pressure to add experience to it we can't let compulsion take the place of good judgment thunderstorm flying I can't wait to read your comments below this video and listen I hope you'll be joining us for our aviation mastery at sea perhaps you've already

just passionate passionate people about aviation all working towards making you a safer smarter pilot family-friendly event as well as we launched in our brand-new copilot course as well and your co-pilots your non flying spouses or friends your go pilots can take their own track as well while you're learning about the latest in aviation technology they can be on the copilot track as well learning how to be an asset in the cockpit how to work as a team and really exercise proper crew resource management aviation master e.com if you wish to learn more about that and reserve one of our cabins we have a limited amount we want to keep this a very special event as well so check that out can't wait to read your comments can't wait to see you in October on the aviation mastery at sea as well enjoy the rest of your day and most importantly remember that a good pilot is always learning have a great day guys we'll see you take a 2 week free trial of our online ground school and see why
