    @Igor S at 4:54 - 5:13 why did it pitch down? I know it is trying to maintain Valpha max but if it would have stopped following Vaplpha max it was at around 200 knots and could have kept climbing at a very good rate. Instead it maintained Valpha max but when it maintained Valpha max the speed decreased and and it pitched down and thus the vertical feet per minute started to decrease. I thought it was suppose to maintain the highest possible lift and if it stayed at 200 knots with the pitch up the aircraft was climbing at a very high rate but it pitched down and slowed the aircraft so it wasn't climbing at its max performance.

    • @wiedehopf9068
      @wiedehopf9068 6 років тому +3

      for a short time the climb rate is better loosing speed. these protections together with pulling the stick full back are connected to avoiding terrain and so they are aimed at the immediate possible flight path. especially in case of wind shear.
      no one would actually keep pulling the stick full back that long if the mountain would follow in 5 miles or so. then green dot would obviously be a much better choice. but that's up to the pilot.

    @lorimeyers3839 11 місяців тому +1

    As a non pilot with zero experience flying whatsoever, this is fascinating to watch.
    So even though you idled the thrust and pulled the side stick up, the aircraft responded by powering the engines to a level that can achieve the pitch you’re inputting?

    Good demonstration :)
    I have two questions:
    - Why is the A/THR LIMITED? Shouldn't be ENGINE THRUST LOCKED -THR LEVERS...........MOVE?
    - Why doesn't TOGA LK kick in directly after ALPHA FLOOR? (Toga Lk kicked in at 5:49 though).

    • @MONRFin
      @MONRFin 6 років тому +5

      Henry 203900 1.) because A/THR is indeed limited by the TLA of the THR levers. It's not locked or off.
      2.) TOGA LK only kicks in after aircraft exited the high AOA protection, and returned to normal flight envelope. On 5:49 as you can see speed increased to a point when it's not in V alpha protection anymore, so the A Floor mode reverts to TOGA LK

    "Because of low speed and thus low alpha"? I'm sure you wanted to say high speed instead of low at 9:00 and hopefully you'll correct it.
    Useful video otherwise showing the flight conditions limitations that an Aribus pilot faces whenever he/she tries going past certain attitude and/or aerodynamic angular limits.

    • @duskedradiance4165
      @duskedradiance4165 6 років тому +7

      It is because a320 was not designed for red bull racing, and flying past the flight envelope is not what passengers want on ANY of their flights, and the flight envelope protection system was made so the plane won't exceed what passengers think it's normal.
      Airbus designed the A320 as a passenger plane, not as a red arrow plane with 180 people on board. Think before hate.

    • @duskedradiance4165
      @duskedradiance4165 6 років тому +4

      Plus, if the pilots are required to fly above the limit (which means putting the plane at risk of, idk snapping the wings off) thry can turn the protection system off, thus making the plane works more or less the same as a Boeing plane.

    • @rigor.m9422
      @rigor.m9422 5 років тому

      @@duskedradiance4165 here's the problem with A FLOOR (and automation in general).
      Of course that, under normal circumstances, the flight envelope is quite reasonable. However, it only works in normal law, which can only operate with all airspeed indicators operational, all ADI operational etc.
      Pilots then get used to the thought that the airbus is un-stallable. So when a pitot tube freezes (air france 447), and the flight computers command alternate law, the pilots get confused and stall the plane.
      Also, in normal circumstances, noone is stupid enough to do anything that the flight envelope would prevent. Noone is stupid enough to be at stall speed+10 with a 20° pitch and not command full thrust. Imo, the flight envelope has done more bad than good. Please give me an example of a boeing plane crash where A FLOOR would have saved lives.

Mini Air Crash Investigation also made a video about an incident where the alpha floor protection saved the plane: ua-cam.com/video/Lksrb21Tbg4/v-deo.html. The outcome of Air France flight 296 was made a lot better by the alpha protection and the workload on the crew of US Airways flight 1549 was reduced by the flight envelope protection (move the sidestick all the way left and the plane turns as quickly as possible, which is important in a situation like that)

    • @igors7694
      @igors7694  7 років тому

      jean-philippe Mirica High AOA protection enables the PF to pull the sidestick full aft in dangerous situations, and thus consistently achieve the best possible aircraft lift. This action on the sidestick is instinctive, and the HIGH AOA PROTECTION MINIMIZES THE RISK OF STALLS OR CONTROL LOSS.

    • @jean-philippemirica7089
      @jean-philippemirica7089 7 років тому +1

      True, i m not aware of all the specificities of the A320... but is the plane stalled ? (7:45) because the variometer indicates a descent with pich up attitude and the speed is very close to the red strip... So the stall alarm/stick shaker didnt trigger at 1.05Vs like in other aircrafts ?

    • @igors7694
      @igors7694  7 років тому +2

      jean-philippe Mirica The relationship between the Pilot Flying's (PF's) input on the sidestick, and the aircraft's response, is referred to as control law. This relationship determines the handling characteristics of the aircraft. There are three sets of control laws, and they are provided according to the status of the: Computers, peripherals, and hydraulic generation. The three sets of control laws are: • Normal law • Alternate law • Direct law.
