Flight manual DG-800S

Free flight
Stalling characteristics
(level and turning flight)
When stalled with flap setting neutral or negative the DG-800S will
continue to fly level.
If the stick should be pulled further the DG-800S will drop the nose or
one wing.
During the stall a large angle of attack will be reached.
At positive flap settings the DG-800S will stall over one wing.
When reaching the minimum speed, the angle of attack has to be
increased remarkably, before the DG-800S stalls so that the stalled flight
is easy to recognize.
With a little stick forward and opposite rudder the DG-800S can be
recovered without much loss of height. Rain does not influence this
behaviour noticeably. The loss of height is appr.30m(100ft) if recovered
immediately.
Stall airspeeds see sect. 5.2.2.
Caution:
Flights in conditions conducive to lightning strikes must be
avoided.
Wing flap settings
Optimal settings depending on the wing loading see sect. 5.3.2.
High speed flying
Flap settings 0°, -5°, -9°
The parallelogram control stick reduces the possibility of pilot induced
oscillations.
The DG-800S can be trimmed almost up to high speeds.
Nevertheless don't release the stick at any time.
Do not exceed the max. airspeeds. (see sect. 2.2!)
Thermalling
Flap setting: + 10°.
+ 13° for narrow thermals
Thanks to the long fuselage, the DG-800S is directionally very stable.
Uneven lift can be optimized because of the excellent roll rate.
