Directed Pilot Application & Practice .75 Parachutes
Postflight critique .15 Weather Briefing
Total 1.50 Model airplane
Objective: Pitch 45 degrees up & down
Student should exhibit proper knowledge and use of controls in pitching up & down including proper pitch angle, rudder control and maintaining wings level.
Select safe altitude - no less than 2000 feet AGL
Establish 170 KTS in MX2, or proper speed in other aircraft
Pitch up to 45 degree up angle, +/- 5 degrees and maintain until airspeed reaches 80 KTS
Pitch down to 45 degree down angle, +/- 5 degrees and recover at initial altitude
Maintain aircraft heading +/-10 degrees
Divide attention between airplane control and orientation
Minimum safe altitude awareness
Stall recognition & avoidance
Flight control utilization and coordination
Proper division of attention
Forces acting on aircraft during steep pitches
Slip & skid indications
Poor use of elevator to pitch and set 45 degree angle
Poor altitude control & unintended bank
Poor use of rudder during high torque & P factor loads
Throttle procedure ignored
Torque & P-factor forces disregarded
Explain & discuss the lesson objective & required knowledge criteria
Instruct that aerobatic pitching must be at least 45 degrees pitch angle, both nose up and nose down with the attendant increase in Gz forces during pitch up and trend toward 0 Gz at pitch down
Establish the proper airspeed, 170 KTS.
Pull briskly to 45 degrees nose up and hold line until airspeed bleeds down to 80 KTS.
Push nose briskly down to 45 degrees nose down angle and recover at entry altitudeq
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 aircraft attitude at 45 degrees nose up & down, Gz forces during pull & push, rudder and aileron required to maintain wings level
Pilot can explain and demonstrate aerobatic pitch up & down to 45 degree nose up and down angles including correcting for torque and P factor while maintaining flight orientation throughout the performance of aerobatic pitch up & down and adhering to the above criteria.
