Flashcards in Flying controls Deck (11):
1
Purpose of the collective CPT?
Sends a control position signal to the HUMS, and sends a signal to the SPI to ensure the MRH is set to min pitch on the ground.
2
Purpse of the trim actuators?
To assist the pilot and reduce fatigue by holding the stick at any selected trim position.
3
Purpose of the yaw pitch control stops?
Limit available pedal movement
Prevent the pilot overloading the control linkages
Prevent damage to the TRA during excessive control inputs
4
At what pressure will the two parallel actuator shear pins fail?
712-920 N
5
What is the minimum stress position whilst collective is in negative pitch?
1.8 degrees
6
When would the SPI have no display?
During flight as the information from the RIU is suppressed by the WOW switch.
7
When would you get a [NO POSN] display on the SPI?
When there is a fault with one or more of the CPT.
8
When would you get a red [FAIL] display on the SPI?
When there Is a fault with the RIU.
9
What is the purpose of the QRVDT?
It acts as a collective pitch anticipator, directly influencing the engines power demand.
10
How is rigging of the QRVDT carried out?
Using the GMT.
