4.12 ACROBATIC MANEUVERS
4.12.1 GENERAL
N O T E
Prior to executing these maneuvers tighten harnesses and check all loose items are
stowed. Start the maneuvers at safe altitude and max continuous power setting if not
otherwise noted.
For maneuver limits refer to Section 2 LIMITATIONS.
After termination of acrobatic maneuvers the artificial horizon (if installed) must be reset if
possible.
At high negative g-loads and zero g-periods it is normal that oil pressure and RPM
indication might drop down momentarily returning to normal status at positive g-loads.
The high permissible load factors of the airplane may exceed the individual physiological
limits of pilot . This fact must be considered when pulling or pushing high g's.
4.12.2 MANEUVERS
CAUTION
Particular caution must be exercised when performing maneuvers at speeds above
Va (158 KIAS). Large or abrupt control inputs above this speed may impose
unacceptably high loads which exceed the structural capability of the aircraft.
Acrobatics is traditionally understood as maneuvers like loop, humpty bump, hammerhead
turn, aileron roll etc..
This manual does not undertake to teach acrobatics, however, it is meant to demonstrate
the plane's capabilities.
For this reason maneuvers are divided into segments. The segments are described.
Limitations are pointed out.
- Segment horizontal line:
A horizontal line may be flown with any speed between V

and V
