Directed Pilot Application & Practice .75 Parachutes
Postflight critique .15 Weather Briefing
Total 1.50 Model airplane
Objective: Steep Turns
Student should exhibit proper knowledge and use of controls in steep turns including rudder, pitch control and maintaining proper bank angle
Select safe altitude - no less than 1500 feet AGL
Establish maneuvering speed
Roll into coordinated 360 degree turn, maintain 60 degree bank +/- 5 degrees, roll out on original heading +/- 5 degrees.
Maintain altitude +/- 100 feet
Divide attention between airplane control and orientation
Perform maneuver in opposite direction
Angle of bank vs. load factors and stall
Minimum safe altitude awareness
Stall recognition & avoidance
Altitude control vs. angle of bank
Flight control utilization and coordination
Proper division of attention
Force acting on aircraft in turns & steep pitches
Slip & skid indications
Inadequate bank & poor altitude control
Uncoordinated use of rudder
Throttle procedure ignored
Torque & P-factor forces disregarded
Disorientation, vertigo & dizziness
Explain & discuss the lesson objective & required knowledge criteria.
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.
Demonstrate and simultaneously explain that the increase in load factor also increases the stalling speed at a significant rate.
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.
Conduct a post flight critique to review procedures, techniques and preview the next lesson.
Participate in discussion of objective, listen, ask questions.
Preview this outline prior to the flight lesson.
Practice and experience the Gz forces, required back pressure to maintain altitude and the increased power necessary to maintain altitude
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.
