Warning: It is urged with emphasis not to take off during rain or with wet wings! (See also Section
4.5.7)
Take-off and Climb
• Line up aircraft with runway. Operate throttle smoothly and not jerkily. Keep elevator back at this stage. If
on rough runways pitch oscillations occur, keep the elevator steady in a neutral position. In general no
counter-measures should be made.
• Lift tailwheel at about 40 kts / 75 km/h by slight pushing. Lift off at 46 kts / 85 km/h. Gain airspeed in
horizontal flight up to 59-62 kts / 110-115 km/h and transition to climbing flight.
• During climb observe the oil temperature and cylinder head temperature. If the limits are reached
(248 deg. F and 482 deg. F / 120 deg. C. and 250 deg. C.) reduce the climb rate and climb on with higher
airspeed.
• The best rate of climb (v
y
) is at 62 kts (71,5 mph / 115 km/h).
• Retract landing gear at a safe height. The landing gear is retracted when both lights are extinguished.
During retraction of landing gear both lights flash "RED". Check automatic circuit breaker (on left-hand
side of landing gear switch), press button if necessary. Main landing gear lever in position „Retract“.
4.5.3 Cruising Flight (including inflight engine stop/start procedures)
Horizontal and Cruising Flight (powered flight)
• recommended cruising RPM 2.000-3.000 rpm
• at 3.000 rpm the resultant cruising speed is 89 kts/165km/h
• Fuel can continue to be drawn from both fuel tanks or either the left or right hand tank. When fuel is taken
from both tanks it is to be noted that the fuel is not drawn evenly. When switching over to the left hand fuel
tank the fuel pump should be switched off, because this tank is serviced by the mechanical engine fuel
pump. When switching over to the right hand fuel tank, switch on the fuel pump.
Warning: If the electrical fuel pump is not switched on during fuel consumption out of the right hand
tank only, the engine will stop immediately.
Change-over of flight conditions (powered or gliding flight)
General:
Because of the special propulsion concept the flight characteristics of the STEMME S10 alter only very
minimal when the configuration is changed from powered to gliding flight or vice-versa.
Regardless of the high reliability one should not depend solely on the propulsion system. Principally the
aircraft should be flown during gliding flight with the same safety strategy with regard to outlandings as if no
propulsion system were available.
