4.6 Flight with the engine removed from the aircraft

The DG-1000M can be flown without the engine when the engine is sent

for a major overhaul, or removed to decrease the aircraft empty weight for

competition flying or for aerobatics.

The following items must be executed: (see sect. 4.10.9 in the maintenance

manual).

1. Remove the powerplant. Spindle drive, gas struts and exhaust system

remain in the fuselage.

Insulate the terminal of the starter motor positive wire (in the engine

compartment).

2. In addition to the on-board battery install a battery in the fin see section.

7.17.6.

3. Carry out a C.G. calculation according to section 6.9. The in-flight C.G.

will be moved forward by approx. 75 mm (3 in.) depending on the

flight mass and empty mass C.G.

This C.G. shift is acceptable, as the forward limit of the in-flight C.G.

for operation with engine removed is 120 mm in front of the C.G. with

engine installed.

4. Fix the limit switch "engine retracted" with a Ty-rap in the actuated

position. Otherwise the DEI-NT will remain in the powered flight

mode.

5. Tape the engine doors carefully with fabric tape.

Note: After switching on the main switch some failure messages will be

displayed. Confirm each message by pressing the selector switch to eliminate

the message.
