Flight Controls

Question 1

ROTATION MODE

Answer 1

The objective of the Rotation Mode is to provide a homogeneous rotation for all possible weight,
CG and configurations, while minimizing the risk of a tail strike.

The Rotation Mode is a pitch rate demand control law, providing tail strike protection.

The flight crew can override the tail strike protection.

The Rotation Mode depends on:
• The pitch rate
• The tail clearance
• The sidestick position.

The Rotation Mode is active from 70 kt during takeoff roll until 10 s after lift-off.

Question 2

NORMAL LAW ROLL RATE PROTECTION

Answer 2

The roll rate requested by the flight crew during flight is proportional to the sidestick deflection, with a
maximum rate of:
• 15 °/s in nominal conditions, when the sidestick is at the stop
• 7.5 °/s in AOA protection or in pitch angle protection, when the sidestick is at the stop.

Question 3

DECRAB FUNCTION

Answer 3

During decrab phase, the aircraft will limit induced roll after pedal input, in order to ease flight crew
control.
