Gulfstream G650ER System Description Manual Quiz

The rudder control system provides electrical and mechanical control of the rudder, as well as fault monitoring and annunciation.

The upper actuator is an EHSA actuator and the lower rudder actuator is an EBHA actuator.

The FCC No. 1 provides two bidirectional ARINC 429 (BD429) buses to each REU, and the FCC No. 2 provides one bidirectional bus to the EBHA REU and one unidirectional bus to the EHSA REU.

<p>When the EBHA is commanded into active mode with normal hydraulic power, the REU and MCE energize a torque motor that moves the two-position solenoid operated valve into the active position.</p> Signup and view all the answers
