Flight Controls Flashcards
1
Q
When do you get a FORCE TRIM INTERPT?
A
> 4 sec interrupted on the ground
NR > 60% and force on via MPD
2
Q
What is the EHV? What does it do?
A
Electro Hydraulic Valve. FMC send Electrical input to hydraulic movement in SAS LVDT sleeve in LAP assembly. Pressurizes on side and depressurizes other side. LVDT reports back to FMC.
3
Q
LVDT?
A
Linear Variable Differential Transducer. Voltage in Voltage out
4
Q
CAS?
A
FMC receives signals from flights control LVDTs send signals to EHV
5
Q
SAS?
A
Rate Dampening
Turn Coordination
Atmospheric Upset Dampening
FMC looks at INU input against flight control LVDTs
6
Q
Heave dampening?
A
Dampens up and down from aerodynamic forces
7
Q
Interrupting force trim?
A
Sends 28 VDc to FMC, FMC will re center SAS sleeve.
8
Q
LVDT voltage?
A
26 Vac from ELC2
