6.16.1. Aerobatic maneuvers develop techniques for obtaining maximum flight performance from the aircraft. Aerobatics explore the entire performance envelope of the aircraft and should be smoothly executed. Aerobatic practice improves feel for the aircraft and the ability to coordinate the flight controls, while remaining oriented, regardless of attitude. Aerobatics increase confidence, familiarize the pilot with all attitudes of flight, and increase the ability to fly an aircraft throughout a wide performance range. The concepts learned from aerobatic practice are applicable in formation maneuvering and other advanced missions. Due to the increased G-force of aerobatics, perform a proper anti-G strain as appropriate.

6.16.2. Training emphasis is on smoothness and proper nose track during the maneuver. Strive to use the briefed entry parameters, but power and airspeed adjustments may be made to enhance energy planning or expedite the profile flow. Normally, the left hand is on the PCL, and the right hand is on the control stick. Indicated torque varies relative to altitude and airspeed without changing the PCL position. See Table 6.1 for a summary of entry airspeeds and power settings for aerobatics.
