|Quoting 777WT (Reply 4):|
On every AA flight I've been on, they deploy the spoilers to full then back to rest during taxi.
|Quoting Starlionblue (Reply 5):|
They don't actually use the spoiler lever for this. The spoilers act as augmentation for the ailerons, and extend when the yoke is rotated from side to side.
|Quoting Santhosh (Reply 8):|
Secondly what types of sensors are used in those aircrafts equipped with EFIS to monitor the actuator position?
|Quoting Jetlagged (Reply 1):|
Some large aircraft, like the 747-200, have a control position indicator which shows rudder, elevator, aileron and spoiler position.
|Quoting Flybyguy (Thread starter):|
Do you get tower or ground crew to observe the tests before departure?
