EFCS stands for
Electronic Flight Control System
How many IFCM's per aileron
1 IFCM
3 roll trim modes
conventional, reference, automatic
how many flight control computers are there
4
the primary purpose of trim
crew relief
1 per wing, moving in opposite directions to control movement along the longitudinal axis
Ailerons
How many hydraulic systems for each IFCM
Two hydraulic systems
a fail light illuminates on this panel
Flight control actuator panel (FCAP or FAP)
FCCs speak on the ____
CCDL (cross-channel data link)
The 4 of these move in the same direction to control movement along the lateral axis
Elevators
what provides surface feedback to the flight control computers
Linear variable differntial transducers
actuator fully extended, ailerons move 100% of command
full-mech
1 upper, 1 lower, controls movement along the vertical axis
Rudder
What components sole purpose if for stick feedback
Aileron Rotary Electro-mechanical actuator
Actuator is fully retracted, aileron moves 50% of command
Part Mech
Utilized for pitch trim
Horizontal Stabilizer
contains 8 LVDTs to provide force output
CSSA (control stick sensor assembly)
cables, rods, and links are only used in
mechanical modes (mech)
