SCHEMPP-HIRTH FLUGZEUGBAU GmbH, KIRCHHEIM/TECK
Arcus M
FLIGHT MANUAL
After lift off at 80 to 90 km/h (43-49 kts, 50-56 mph) – depending on loading
and flap setting – the trim can be set so that minimal force is felt in the
elevator control.
Normal towing speed is 110 to 130 km/h (59-70 kts, 68-80mph) with a flap
setting "+2". At higher flying masses the towing speed is about 120 to 140
km/h (65-76 kts,75-87 mph).
At higher towing speeds, negative flap settings as far as flap setting "S" can
be used. The flap setting can be chosen so that pleasant high control forces
can be adjusted with the trim.

Only small control surface deflections are normally necessary to keep
position behind the tug.
In gusty conditions or when flying into the propeller slip stream of a
powerful tug correspondingly greater control stick movements are
required.
The undercarriage may be retracted during the tow; this is not, however,
recommended at low altitude, as changing hands on the stick could easily
cause the Arcus M to lose station behind the tug.
When releasing the tow rope, pull the yellow T-shaped handle fully
multiple times and turn only after the rope has definitely disconnected.
