Objective:  Steep Turns

Student should exhibit proper knowledge and use of controls in steep turns including rudder, pitch control and maintaining proper bank angle    

  1. Select safe altitude - no less than 1500 feet AGL
  2. Establish maneuvering speed
  3. Roll into coordinated 360 degree turn, maintain 60 degree bank +/- 5 degrees, roll out on original heading +/- 5 degrees.
  4. Maintain altitude +/- 100 feet
  5. Divide attention between airplane control and orientation
  6. Perform maneuver in opposite direction
   
Elements:
  1. Proper Airspeed
  2. Angle of bank vs. load factors and stall
  3. Minimum safe altitude awareness
  4. Stall recognition & avoidance
  5. Altitude control vs. angle of bank
  6. Flight control utilization and coordination
  7. Proper division of attention
  8. Force acting on aircraft in turns & steep pitches
  9. Slip & skid indications
  10. Rudder coordination

Common Errors:
  1. Inadequate bank & poor altitude control
  2. Uncoordinated use of rudder
  3. Inadvertent stall/spin
  4. Throttle procedure ignored
  5. Torque & P-factor forces disregarded
  6. Disorientation, vertigo & dizziness

Instructor Actions:
  1. Explain & discuss the lesson objective & required knowledge criteria.
  2. Instruct that aerobatic steep turns must be at least 60 degree bank angle, aircraft requires significant up elevator to maintain altitude, with the attendant increase in Gz forces, 2 Gz at 60 degrees bank.
  3. Demonstrate and simultaneously explain that the increase in load factor also increases the stalling speed at a significant rate.
  4. Establish the proper airspeed, initiate a level roll into a 60  degree bank while increasing back pressure on the elevator to increase the angle of attack, AOA, and because of the increased load factor, more power must be added to hold the entry altitude.
  5. Conduct a post flight critique to review procedures, techniques and preview the next lesson.

Pilot Actions:
  1. Participate in discussion of objective, listen, ask questions.
  2. Preview this outline prior to the flight lesson.
  3. Practice and experience the Gz forces, required back pressure to maintain altitude and the increased power necessary to maintain altitude

Completion Standards:
Pilot can explain and demonstrate an aerobatic steep turn including the increased load factors, stall speed, and added power necessary to maintain a constant altitude turn at 60 degree bank angle in coordinated flight, and roll out on heading while maintaining flight orientation throughout the performance of aerobatic steep turns and adhering to the above criteria.
