    excellent and thanks for the refresher.
    The only caveat I'd add to significantly lowering airspeed well below maneuvering speed in turbulence would be the possibility of not only an accelerated stall, but also of an inadvertent spin in IMC conditions.
    We're all taught rudder opposite to recover from a spin in vmc, but not many are taught to step on the high wing (in the turn coordinator) to recover in IMC (and loss of fuel as a result of an inverted spin is a whole different question - I'd heard of turbulence flipping a Cessna 172 upside down during mountain flying at ground school - my personal limits for mountain flying are that winds aloft have to be less than 20kts but that alone isn't a guarantee.
    At an air safety institute seminar a few years back there was an accident case study where such a likely cause was presented.
    I wouldn't be so sure about entering an accelerated stall in turbulence and IMC so not sure about slowing down well below Va.
    Thanks much, safe flying and great summary.

    Great explanation!Just learned many things here and got some more questions to search for answers.
    Well, one of them is: why the yelow region is bounded by 4.5G like green region ? I mean, if yellow arc stands for caution and fly in smooth air, does it mean a not-smooth air is what makes you bounce over 4.5G?
    In my opinion, like other types of graphs ive seen around (elec. or mec. engineering) its like another curve is missing. May be a descent curve from 4.5G at maneuvering speed down to 0G in red line.
    Thanks anyway for your time

    For certified aircraft, VNE is the highest speed that the manufacturer has certified the airplane for. It is not just rough air or maneuvers that are of concern, but aerodynamic conditions like flutter as well. Some of these conditions can be divergent which means that once it starts, recovery is not possible. Essentially, nobody knows how the plane will behave in this region. If you are tempted to burn off some altitude in smooth air, be aware that you will be entering dark territory. With ADS-B, the FAA will be able to review your flight if it comes to their attention. Generally, the FAA won't look at that record unless there is a triggering event which can be as simple as a complaint from someone on the ground. At that point, the lawyers get involved.

    This might sound silly, but with stall speeds, do you use power-on or power-off stall speeds? This has to do with both standard and aerobatic flying (I'm basically doing some performance estimates of WWII aircraft and I'm not sure which figures to put in).

  • @rsb3006
    @rsb3006 6 ปีที่แล้ว +1

    Hey, I love your videos and I'm binge watching them now. However, I'm skeptical when you say it's "impossible" to get into the structural damage zone when below maneuvering speed. What if it's a REALLY intense storm (obviously you should not be flying in)? I would think that the updrafts could still apply such a force to the wings that you can still get to the structural damage zone.

    Greetings Jon! I have a quick question, I was looking over one of the aviation questions that asks, “ If the airspeed is increased from 110 knots to 150 knots during a level 45° banked turn, the load factor will...”
    At first I chose the load factor will increase as well as the stall speed. But the correct answer appears to be the load remain the same but the radius turn will increase.
    But at the above quiz question, I thought when you make a turn your load factor and stall speed will automatically increase? Or is it because the throttle is increased that’s why there’s no change in load factor and stall speed?
    Or that’s just say I don’t increase the throttle, and I make a turn, then in this case both the load factor and stall will increase?
    Thank you!

    Why stall speed is higher when negative load factor of 1?

  • @K0S0s
    @K0S0s 2 ปีที่แล้ว

    Published Va speed is the lesser of the two, so flying below Va means you're just as safe to do full nose down deflection as you are to pull up at full deflection.

      So long as you can get your medical card I see no reason why you couldn’t learn to fly. I am 43 and would get my private pilot license if I could afford it. I would assume being a pilot is like having a CDL, you have to be able to get medical clearance/card.

    This is a good presentation except for one fact. If you overload the airplane it can fly straight okay but if you turn you start ramping up the forces and you slam into the ground. You might have four or five times the way to the airplane of Lyft in a straight line at a high speed but if you turn a little bit that's not going to be true it's going to be a lot less. All of these aircraft take off overloaded in a straight line and barely make it they get off the ground a little ways and they turn a little bit and that's when she crashes.

    • @fly8ma.comflighttraining199
      @fly8ma.comflighttraining199  8 หลายเดือนก่อน

      This video isn't about the weight and balance of the aircraft. It is about the load factor on an aircraft in reference to speed which is not the same as exceeding the gross weight of the aircraft. Which if you do happen to exceed the gross weight it can have dire consequences such as not even being able to leave ground effect or worse stall on takeoff.

      @@fly8ma.comflighttraining199 I thought of the video about airplanes and not smacking into the ground.If It was just about you and the chart I guess the fact that an airplane turning stalls and spins into the ground at a much higher speed. I think it's a great video if you fly an airplane that only goes straight.

    • @markmcgoveran6811

      @@fly8ma.comflighttraining199 I also mentioned turning. You have that pilot thing where you want to focus on me being wrong but you want to ignore where I'm right. Your stall speed goes up when your turn radius radius decreases perfect weight perfect balance perfect pilot perfect perfect perfect perfect. If you begin to turn or you are turning in any of these conditions on this chart you have a higher stall speed any chance to spin into the ground because of the radius of the turn. If I ever need a pilot or I ever need lessons on flying in a straight line and never turning you're my go-to guy.
