A

Throttles advanced for takeoff.

  • depressurizes for rejected takeoff when throttles retarded
  • outflow valve opens automatically after 60 seconds & not in the air
38
Q

Q

What does a clapper do in the elevator control system?

A

If control column becomes disconnected and there is no jam, CLAPPER will cause both columns to move & both elevators to move. If there is a jam, CLAPPER will allow non-jammed side to move independently.

48
Q
