Exercise 20: Steep turns



In this lesson, the student will learn how to turn the helicopter at a constant bank angle of 30° or more, maintaining a constant airspeed, altitude and balance. All turns will be level initially to enforce correct entry technique and roll out technique.




  1. Fully brief the forces in the turn and the effects on total rotor thrust, pitching moments and speed.
  2. Recap the effects of dissymmetry of lift in the turn
    • Turning left – Forward cyclic pressure
    • Turning right – Aft cyclic pressure
  3. Recap spiral dive recovery
  4. Demonstrate a 360° Steep turn at 30° bank angle maintaining a constant height and speed between 60-70kts:
    • Climb to at least 800FT AGL
    • Select a suitable reference point on the horizon
    • Initiate a turn from the reference point, ensuring that the area is clear in the direction of the turn. Keep a good LOOKOUT!
    • Coordinate the roll in, and maintain a constant roll rate by visually selecting the bank angle by which the disc cuts the natural horizon, scanning the AH for further accuracy.
    • Hold cyclic pressure for flap back/flap forward
    • Rolling through 15°, increase power and apply left pedal for balance
    • Continue scan through the turn, assessing attitude, bank, balance and relevant instruments.
    • Ensure that the student does not fixate on the scan, and keeps a good lookout, eyes ahead of the direction of turn
    • 10° before assigned reference point initiate the roll out.
    • Roll wings level by applying cyclic in the opposite direction of turn, release cyclic pressure holding for dissymmetry of lift, reduce power and apply right pedal for balance.
    • Continue straight and level.
  5. Allow the student to practice left and right turns.
  6. Once the student is proficient in the left and right turns, combine left and right turns to form a flat figure of 8.




At the completion of this exercise the student must be able to smoothly enter, maintain and roll out of steep left and right turns, and combinations of left and right turns, whilst maintaining a constant bank angle, airspeed, altitude and balance. The student will exercise good airmanship throughout, maintaining a good lookout for other aircraft, actively scanning instruments and correcting for any deviations in the turn.
