What is Alpha Prot Airbus?

In all Airbus aircraft there is a black and amber band at the lower end of the speed tape. This band is known as the alpha prot. Once the aircraft speed is in this range, the high angle of attack protection activates.

What does Alpha floor mean?

A system designed to prevent an aircraft from reaching very near its critical angle of attack because of slowing down too much. The system automatically increases the thrust of the aircraft when speed is predicted to reach or exceed the critical angle of attack.

What is Alpha Max in aviation?

The highest degree of displacement from (relative) horizontal (the airstream, not the ground level, nor the theoretical flat gravitational surface), that an airplane can achieve and still maintain forward flight (without stalling), at the speed that the aircraft is travelling.

What is Alpha protection A320?

“Alpha protection” is a system which prevents the angle of attack from getting too high. This is done by software monitoring the plane’s angle of attack sensor. When a high alpha situation is detected, the software lowers the nose of the plane to maintain high but still safe angle of attack.

Can Alpha floor be disengaged while in Alpha protection?

The only way to cancel alpha floor is by disengaging the A/THR function.

How do I get out of alpha floor?

When the alpha floor protection is triggered, the A/THR triggers TOGA on all engines. The FMA displays A FLOOR, that changes to TOGA LK, when the aircraft angle-of-attack has decreased. TOGA/LK can only be deselected by turning the A/THR off.

What is a floor in Airbus?

Alpha floor is a thrust function which provides TOGA thrust regardless of thrust lever position in Airbus. From Airbus Technical Digest FAST 20: Alpha Floor is a low speed protection (in normal law) which is purely an autothrust mode. When activated, it provides TOGA thrust.

What is alpha floor after take off?

Thus when the crew retracted the flaps the plane went into “alpha floor” event. This is where the airspeed is too low and the aircraft is in danger of stalling. A disaster was averted because once again the aircraft’s safety systems took over, adding power and lowering the nose slightly, preventing it from stalling.

What is the Airbus equivalent to Boeing 787?

Airbus A350
The Airbus A350 and Boeing 787 represent the very best in innovation, ideas and cutting edge technology from their respective companies. Both these planes, how much ever different, are pretty much indistinguishable when it comes to the gargantuan impact they have had on the aviation industry!

What does Neo mean in Airbus?

New Engine Option
The addition of “neo” stands for “New Engine Option”. The aircraft is 15 percent more fuel efficient than today’s comparable models. It also shows impressive figures in terms of noise reduction: the 85 decibel maximum noise-level contour of a starting A320neo is around 50 per cent lower than that of the current A320.

How do I get rid of alpha floor?

What does a floor mean in Airbus?

Alpha floor protection is an Airbus low speed protection available in Normal Law which will command full power from the engines if the system detects the aircraft is dangerously close to a stall. The aircraft will pitch up to max Alpha, engage TOGA thrust and climb away.
