FLIGHT MANUAL TSA-M, VARIANT S6

Doc.-No.:P400-006.000 E

Page: 4-24

Revision: 1

Date of Issue: 07. October 2008

Agency approved

Date of Rev.: 28.01.2011

4.7.3.4 Soaring

1. Flaps

Circling in thermals: „TO / LDG 1“

Flight between thermals:

„NEUTRAL“

Warning:

The voltage must not fall below the minimum of 11.5V during

soaring flight. If the minimum voltage is reached the engine

has to be restarted with windmilling immediately.

Note:

Best glide-ratio occurs with flaps set to „NEUTRAL“, lowest

sink-rate with flaps set to „TO / LDG 1“.

4.7.3.5 Engine-Restart (Transition to Powered-Configuration)

Warning:

When restarting the engine in flight with a windmilling

propeller and at high air-speed, the THROTTLE must be set

to IDLE. Otherwise the engine can exceed its maximum

RPM immediately after restarting.

Warning:

If the engine is running (windmilling) do NOT use the starter.

The engine could be damaged.

Caution:

With low battery voltage near minimum value of 11.5V the

engine restart is only possible with windmilling.

Note:

During engine air-start, the altitude-loss is minimum 690 ft /

210 m, depending on metereological sink-rate.

Normal airstart: appr. 100 m / 330 ft (for 90 s propeller pitch)

Windmilling: appr. 210 m / 690 ft (with acceleration to

150 km/h / 81 kts)
