PLT112: Use of Flight Controls
What code PLT112 covers, why the FAA tests it, and how to study Use of Flight Controls before your checkride.
Recall aircraft controls - proper use / techniques
What this means for your checkride
Using the flight controls properly means coordinating aileron, elevator, and rudder for the maneuver and the wind: aileron into the wind while taxiing, coordinated aileron and rudder in turns, and the right pressures for the airspeed. Control effectiveness drops at low airspeed and rises with speed.
Correct control use is basic airmanship, so the FAA tests coordinating the controls and positioning them for wind on the ground and in flight.
Pilots fly turns with aileron alone. Aileron creates adverse yaw, so a coordinated turn needs rudder in the direction of the turn to keep the ball centered.
Where to study it
A code on your test report is an area of deficiency. An authorized instructor must review it with you and endorse that review before you take the practical test, and the examiner may revisit it during the oral. Study it until you can explain it out loud, not just recognize the answer.
