The flight controls on the Airbus A330, for example, are all electronically controlled and hydraulically activated. And somewhere in between, there is a point where alpha floor does not make sense anymore as the best way of protecting the aircraft in all possible scenarios. The only thing to do to save the airplane is to pitch down (nose down to unload, g-load wise), recover speed, increase thrust smoothly and recover the flight path. The project uses theOmegaHangars new Airbus A320/30/40 cockpit and systems and new Airbus A330-200 models. Beginning with a cockpit texture replacement for the JARDesign A330. The alpha protection - officially called the high angle of attack protection - is not only a feature of the A330 but also A320, A340, A350 and A380. In both cases, it would do more harm than good to have TOGA thrust, which can cause a pitch up moment, that is hard to control manually at these high altitudes. You are NOT really need Download Protection option and you can Remove it. Maybe the Auto Flight System disengages, because the speed drops below V_LS minus 5. If you are flying in alternate law (which we do in the simulator for stall training), the stall warning will activate instantly. It does not take a lot (sudden change in wind, turbulence, excessive pitch input in manual flight (which you should not do at cruising altitude)) to let the speed drop to V_ALPHA_PROT (which is very close to green dot in this thin air near max altitude). Other example: you are in cruise flight, near MAX REC ALT and near green dot speed. Simulation of the A330 focused on the day to day operation of the aircraft from the left seat The cockpit is equipped as it is with large airlines. If everything goes well (as the engineers intended the protection to work), the speed decay is prevented just in time, so that the low speed protection does not need to be activated. To prevent the aircraft from automatically pitching down, the auto thrust commands TOGA. That is where ALPHA FLOOR kicks in, because the PRIMs calculate, that you are in a low-energy state. Environmental influences (loss of headwind, increase of tailwind, gusts) or a shallow descent or even level-off could even further let your speed drop. One example for ALPHA FLOOR: you are in approach with Flaps Full, Idle Thrust (Manual Thrust) and nearing V_APP. And that protection is working above M.53. For safety, child seats are not permitted in the Delta One cabin. Stall protection is primarily done by the low speed protection (high AOA protection of normal law), where the aircraft commands nose down so it does not decelerate below V_ALPHA_PROT (thus maintaining actual AOA <= ALPHA_PROT). Our Airbus A330-300 aircraft offers a variety of signature products and experiences. That can of course a possible outcome, if you don't increase thrust to accelerate. It does not primarily protect the aircraft from stalling. I was comfortable and at ease in the cockpit immediately. Try to see it this way: ALPHA FLOOR is a protection function of the AUTO THRUST SYSTEM, and it protects the aircraft from excessive speed decay. JRD was an A300 Examiner, and he found the A330 easy to fly.
