Flight Controls Flashcards
what are the primary flight controls
Rudder, elevator, and ailerons
What are the secondary flight controls
electrically actuated pitch / roll / yaw trim systems and a rudder trim aid device (TAD)
What do the Green TRIM OFF and TAD OFF annunciators mean when illuminated
the Trim disconnect switch is used.
What is all included in the aileron system
ailerons, control sticks, push-pull rods, and bell cranks
How are the front and rear cockpits connected (AILERON)
through an interconnected tube
What is the travel limitations of the ailerons
20 degrees up and 11 degrees down.
The Ailerons are _____ with weights installed on the ____ of each aileron
mass balanced, leading edges
What is included in the elevator system
elevator, control sticks, push-pull rods, downsprings, cables, bellcranks, and a bob-weight
The elevator is limited to ____ trailing edge up and _____ trailing edge down deflection
18, 16 degrees
How is the elevator balanced
With weights located in the elevator horns. Two downsprings fitted to the elevator bellcrank provide a balanced control feel
What is the purpose of the bobweight? Where is it installed
Its installed on the front control stick which increases stick forces as G-load on the aircraft increases, to improve control feel and help prevent overstressing the airframe
What is included in the rudder system
rudder, rudder pedals, cables, pulleys, and a bellcrank, with one push-pull rod and two rudder centering springs
How are the front and rear pedals connected
tie rods
How far can the rudder pedals be adjusted
7inches from forward to aft
Rudder travel is limited to ____ and _____
24 left and 24 right
How does the TAD work
It senses engine torque, altitude, airspeed, and pitch rate and computes a desired rudder trim tab position
Once T/O trim is set when is the next time the system makes inputs
The aircraft accelerates to at least 80 KIAS and there is no weight on wheels
When does the stickshaker activate
15-16 units on the AOA or 5-10 knots above stall speed
When does the AOA indexer in the upper left side of the flareshield illuminate
when the gear are down and locked
Optimum approach airspeed will decrease approaximately ___ for every ____ of fuel used
1 knot, 100lbs
How is the maximum endurance represented on the AOA gage and at what unit
a white diamond at 8.8 units. Yields greatest amount of flying time per poud of fuel remaining
How is the maximum range represented on the AOA gage and at what units
a white triangle at 4.9. Yield greatest range per pound of fuel remaining
