Answer 24

• pedal braking applied
• either thrust lever advanced after landing
• speedbrake lever is moved to the DOWN detent after the speedbrakes have deployed on the ground
• DISARM or OFF position selected on the AUTOBRAKE selector
• autobrake fault
• normal antiskid system fault
• loss of inertial data from the Inertial Reference Units (IRUs)

Question 25

HOW IS THE SYSTEMS SEQUENCING THE BRAKING APPLICATION?

Answer 25

ALTERNATING THE WHEEL PAIRS AT EACH BRAKE APPLICATION, THIS REDUCES THE BRAKES APPLICATION FOR EACH BRAKE
