Flashcards

Pitch Attitude Protection

A system that limits the aircraft's pitch attitude to a safe range (+30° and -15°) in emergencies to prevent hazardous situations arising from excessive pitch.

Load Factor Protection (LFP)

A feature within Pitch Attitude Protection that allows an immediate 2.5g maneuver without delay in emergency situations, aiding obstacle clearance.

Excessive Nose-Up Attitude

A dangerous pitch attitude where the aircraft's nose is too high, leading to rapid energy loss.

Excessive Nose-Down Attitude

A dangerous pitch attitude where the aircraft's nose is too low, leading to rapid energy gain.

Load Factor Limitation

A safety feature limiting the maximum load a commercial aircraft can experience during maneuvers, automatically adjusted based on slat extension status. This is to account for potential collisions, or CFIT.

High AOA Protection

A system that limits the aircraft's angle-of-attack (AOA) to a safe value (αPROT) when it exceeds a certain threshold. It prevents stalls and maintains control.

What is αMAX?

The maximum angle-of-attack (AOA) the pilot can manually input into the flight control system. It's the upper limit set by the system.

How does the flight crew affect AOA?

The flight crew can increase the angle-of-attack (AOA) through their input, but only up to the maximum value of αMAX. This means they can't exceed the system's limit.

What does AOA Protection do?

The AOA Protection system limits the aircraft's angle-of-attack (AOA) to a safe value (αPROT) when it exceeds a certain threshold. It prevents stalls and maintains control.

What is αPROT?

The maximum permissible angle-of-attack (AOA) allowed before the AOA Protection system activates. It defines the safety boundary.
