FLIGHT SPOILER CONTROL SYSTEM - ADJUSTMENT/TEST
_______________________________________________
1. General_______
A. There are three tasks in this procedure. There is a task for the operational test, the adjustment and the system test of the spoiler control system.
B. The spoiler control system gives lateral control and speed brake signals to the flight spoiler actuators through the spoiler mixer. The speed brake signals also control the ground spoilers.
C. You must not use the decals installed on the aileron control wheels during the adjustment or the test of the spoiler control system. The decals are for flight crew use only.
D. Before you do the adjustment or the test of the spoiler control system, the adjustment of these systems must be correct:
(1)
The aileron control system (Ref 27-11-00/501).
(2)
The trailing edge flaps (Ref 27-51-00/501).
(3)
The speed brake system (Ref 27-62-00/501).
