NOTE
4.12.2 MANEUVERS
Utility category:
Stall:
Level and accelerated stalls up to MTOW, Airspeed and G-limits in the Utility category are to be
respected.
Chandelle:
Airspeed and G-limits in the Utility category must be respected.
Lazy eight:
Airspeed and G-limits in the Utility category must be respected.
Steep turns:
Airspeed and G-limits in the Utility category must be respected.
Acrobatic category:
Horizontal line: A horizontal line can be flown with any required speed between V
S
und V
NE
.
45° Climbing line:
With max. continuous power the aircraft can sustain this line.
The speed will not drop below 80 kts / 144 km/h.
90° Vertical climbing line:
A vertical climbing line can be entered with any required speed between
V
S
und V
NE
.
In long zero-g lines the propeller can go in high pitch due to a loss of oil pressure.
By applying any g-load the oil pressure will be restored.
45° Descending line:
Reduce power to prevent exceeding V
NE
.
90° Vertical descending line: Reduce power to prevent exceeding V
NE
.
Snap roll:
Snap rolls must not be flown above 174 kts / 322 km/h
Aileron roll: Full aileron deflection rolls can be flown up to 225 kts / 417 km/h = V
NE
.
Quarter-looping upwards:
Recommended minimum entry speed is 100 kts / 185 km/h. If another
maneuver shall follow in the vertical line, more speed is required.
A full round loop requires an entry speed of at least 100 kts / 185 km/h.
Gyroscopic manoeuvers:
All maneuvers with high rates of rotation in the pitch- and yaw axis cause
high stress to the crankshaft!
There is no RPM limitation for gyroscopic maneuvers
Be aware of the risk of a higher engine wear during gyroscopic maneuvers!
