4.5.7
Approach and landing
Land always in the gliding configuration, engine retracted!
4.5.7.1 With the engine retracted
It is recommended to dump the waterballast before landing on airfields.
Dump the ballast before an outlanding in any case.
Abeam the landing point extend the landing gear and set the wing flap to
8° or to L.
Use L in calm weather. With gust and crosswinds 8° is recommended.
In calm weather approach with ca. 105 km/h (57 kts) (ballast dumped!).
With strong wind fly faster!
The very effective Schempp-Hirth dive brakes make a short landing
possible.
It is possible but not necessary to use a side slpip as a landing aid.
While side-slipping, the rudder is sucked into its displaced position. So it
is recommended to practice side-slipping at a higher altitude.
Strong crosswind offers no problem.
Do not approach too slowly with fully extended airbrakes otherwise the
aircraft may drop during flare out.
When flaring out keep the airbrake setting you were using, opening them
further may drop the sailplane.
You can land the DG-800B on soft fields with the landing gear extended,
as there is no tendency of nosing over, if the stick is pulled backwards.
During ground roll the wing flaps may be kept in the landing position.
Clean the landing gear and tow release after landing in a muddy field.
Dirt in the front strut can keep the landing gear from locking over center
next time. Simply hosing with water is the best cleaning method.
4.5.7.2 Landing with the engine extended and stopped
See emergency procedures sect. 3.14.
Land with the engine extended only if the engine can't be retracted.
4.5.7.3 Landing with the landing gear retracted:
Wheel up landing is not recommended see emergency procedures
sect. 3.16.
After wheel up landing check the fuselage belly and the tow hook for
damage.

4.5.7.4 Landing with asymmetric waterballast
See emergency procedures sect. 3.15.
4.5.7.5 Extension and starting the engine after landing
The same procedures as in flight may be used after landing for taxying.
Operate the ignition switch after touch down. On uneven runways extend
the engine after stopping the aircraft to reduce wear of the extension-
retraction unit.
4.5.7.6 Engine retraction on the ground
Caution:
After ground test runs or after taxiing don’t retract the engine
immediately. Allow the engine to cool down several minutes.
For retraction turn the propeller by hand into position, don’t use the
starter motor.
The engine will be retracted automatically. To interrupt the retraction
procedure proceed as follows:
Up to ser.no. 8-218: Lift the cover of the manual extension-retraction
switch. Further retraction via the manual switch or by putting down the
red cover.
From ser.no. 8-219 on: Push the manual switch up or down to switch
off the automatic system. Further retraction via the manual switch or by
switching the ignition on and off.
