Arcus M
FLIGHT MANUAL
Flight (ctd.)
b)
Power plant extended
As the propeller used is mainly pitched for good climb (rather than for
high cruise), the speed attained in level flight at 6600 RPM is approx.
150 km/h (81 kt, 93 mph) with flaps set at “-1”.
At this speed the “Arcus M” shows a stable behaviour and is easy to
control.
Flown in a shallow dive, the maximum permitted engine speed of
6600 RPM must not be exceeded!
Idling only in emergency
With engine idling (throttle closed), descending flights are only allowed
for short periods.
Long idling periods must be strictly avoided to prevent the danger of an
engine failure due to carbon accumulation on the spark plugs!
CAUTION
:
On longer flights with the throttle closed it is therefore necessary to
open it momentarily at least once every minute to keep the engine
clean!
NOTE:
Flight conditions under lightning strikes must be avoided!
