Speedbrake Autostow System
1. General
The 757-200 speedbrake control system is modified for aircraft that incorporate APB winglet retrofit kits. The basic manual and auto speedbrake system remains the same as the 757-200. Modifications to the system include the addition of a mechanism that can automatically retract the speed brake handle and a Speedbrake Autostow Control (SAC) module to control the operation of the mechanism as a function of aircraft velocity, weight and flap position.
System components include a speedbrake handle retract mechanism, electrical actuator, SAC module, and a modified wiring harness with the correct pin select for the autostow system.
NOTE: Aircraft specific wire harness information is provided in APB Wiring Diagram Supplement, Reference [AP57.2-0615-2].
