4.8.3.4.0.A.1
ATP ATA ARA ADX
Knowledge Code: PLT473
What is the purpose of an elevator trim tab?
*A) Modify the downward tail load for various airspeeds in flight eliminating flight-control pressures.
B) Adjust the speed tail load for different airspeeds in flight allowing neutral control forces.
C) Provide horizontal balance as airspeed is increased to allow hands-off flight.

4.8.3.4.1.B.1
ATP ATA ARA ADX
Knowledge Code: PLT107
Which is a purpose of wing-mounted vortex generators?
*A) Delays the onset of drag divergence at high speeds and aids in maintaining aileron effectiveness at high speeds.
