Warnings
All sailplanes, especially those with retractable powerplants, are very complex
technical devices. If you don’t use yours as it is intended and within the certified
operating limitations or if you fail to carry out proper maintenance work, it may
harm your health or place your life in danger.
Prior to flying the aircraft read all manuals carefully and regard especially all
warnings, caution remarks and notes given in the manuals.
 Never take-off without executing a serious pre-flight inspection according to the
flight manual!
 Never take-off with a motorglider without checking the max. engine RPM and
the ignition circuits!
 Always respect the relevant safety altitudes!
 With a motorglider never rely completely on the engine extending and starting.
Plan your flight path so that you are always able to carry out a safe outlanding if
necessary. Be aware that with the engine extended but not running the rate of
sink increases remarkably. This means that with a motorglider you have to
decide earlier for an outlanding than with a pure sailplane.
 Selflaunch only if you are sure that with an engine failure during the initial
climb there is the possibility to execute a safe outlanding or to return to the
airfield.
 Respect the stall speeds and always fly with a safety margin above the stall
speed according to the flight conditions, especially at low altitudes and in the
mountains.
 Use only the types of fuel and oil for your motorglider as specified in the flight
manual.
 Use only the battery chargers as specified in the flight manual.
 Don’t execute yourself any work on the control system except for greasing.
 Repairs and maintenance work should only be accomplished by the
manufacturer or at certified repair stations rated for this type of work. A list of
stations which have experience with DG aircraft may be obtained from DG
Flugzeugbau..
 Even if no annual inspections are required in your country, have your aircraft
checked annually (see maintenance manual section 2).
 Please pay attention to our web-site www.dg-flugzeugbau.de. There you will
find the latest technical notes and service information for your glider:
http://www.dg-flugzeugbau.de/en/maintenance-service-aircraft/technical-notes
The „DG Pilot Info“ informs you immediately by e-mail about the publication
of new technical notes and service information.
