- Segment line 45° climbing:
The plane will follow the line at max. power. The speed will not decrease below 80 KIAS.
- Segment line 90° up:
Any entry speed may be used. Out of a horizontal pull-up at 200 KIAS the vertical
penetration will be 2.500 ft. The speed will gradually decrease to 0.
N O T E
In extremely long lines an RPM decay may occur. This is related to a loss of oil pressure.
Positive g´s should be pulled immediately in order to protect the engine. Oil pressure will
return immediately.
- Segment line 45° diving:
Throttle must be reduced in order to avoid exceeding V
ne
.
- Segment lin 90° diving:
Throttle must be reduced to idle in order to avoid exceeding V
ne
.
Above segments may be filled up with aileron rolls on snap rolls. Watch V
A
= 158 KIAS for
aileron rolls with max. deflection.
Snap rolls should not be performed at speeds above 140 KIAS.
- Segment 1/4 loop, climbing:
The minimum recommended speed is 100 KIAS. If the maneuver is to be followed by a
vertical line, a higher entry speed is required depending on the expected length of the
line. A complete loop can be performed at speeds above 100 KIAS.
Since the maximum horizontal speed is 185 KIAS, higher speeds should be avoided in
acrobatics since an unnecessary loss of altitude would occur.
- Torque maneuvers:
All maneuvers with high angular velocity associated with high propeller RPM must be
considered dangerous for the engine crankshaft.
Although wooden composite propeller blades are used, the gyroscopic forces at the prop
flange are extremely high.
If performing a gyroscopic maneuver such as flat spin, power on, or knife edge spin, reduce
RPM to 2400 in order to minimize the gyroscopic forces.
