Directed Pilot Application & Practice .75 Parachutes
Postflight critique .15 Weather Briefing
Total 1.50 Model airplane
Objective: Full Loops
Student should exhibit proper knowledge and use of controls in pitching up, maintaining wings level, use of outside cues to maintain wings level and proper heading throughout entire loop, recovery straight & level and on heading and starting altitude.
Select safe altitude - no less than 2000 feet AGL
Establish at least 160 KTS in MX2 at full throttle, or proper speed in other aircraft
Briskly pull to 4-5 Gz and hold back pressure to approximately 11:00 position inverted, ease back pressure slightly to "float" top of loop, then increase back pressure again at approximately the 1:00 position until level again
Use right rudder as necessary to maintain headingq Maintain wings level throughout figure
Aircraft should finish loop at entry altitude +/- 100 feet and on heading +/- 10 degrees
Minimum safe altitude awareness
Flight control utilization and coordination
Proper division of attention
Forces acting on aircraft and controls required at various angles of pitch: 0-160 degrees, 160 - 200 degrees, 200 to 360 degrees
Proper use of rudder
Stall recognition & avoidance
Soft pull of less than 4-5 Gz
Unintended bank during pull
No float at top of loop
Soft pull in 2nd ½ of loop
Finish much higher or lower
Tall, oval shape
Explain & discuss the lesson objective & required knowledge criteria, and larger Gz forces than past experiences
Instruct that loops should start with a brisk pull of 4-5 Gz and hold until near top of loop.
Explain "float" at top of loop and then increasing pull to finish loop at starting altitude
Establish the proper airspeed, at least 160 KTS, at full throttle.
Pull briskly to 4-5Gz and hold back pressure until approx 160 degree position.
Ease off back pressure between 160 degrees and 200 degrees pitch angle, and then increase back pressure to finish at 4-5 Gz straight and level.
Demonstrate partial loops to 90 and 180 degrees - No difference in technique
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 loops including brisk initial pull, float at top, and increasing Gz at finish, recognizing higher Gz forces and the 0 Gz environment at inverted flight
Pilot can explain and demonstrate loops including proper pitch control and float, correcting for torque and P factor while maintaining flight orientation throughout the performance of loop and adhering to the above criteria.
