Cruise

Aircraft at MTOM, recommended cruise power of 5300 RPM at 15°C / 59°F at sea level altitude, flaps

set to negative position (-5 degrees):

Sinus

912 LSA

cruise airspeed

110 kts

Best economy cruising level is 7500 ft . There, cruise performance is equivalent or better than above

due to IAS-TAS relation, but fuel consumption is lower.

At these parameters the fuel burn is 2.9 US gal (11.2l) per hour. For detailed fuel consumption deter-

mination for various cruising regimes consult the Rotax 912 UL Operators manual.

Descent

Typical sink rate, with flaps set to 2

position and airbrakes fully extended, measures 880 fpm

(4.4 m/h) at 50 kts (92 km/h) and 1160 fpm (5.8 m/s) at 60 kts (110 km/h).

Sinus

912 LSA

max. sink rate with airbrakes extended at 90 km/h

(48 kts

), full flaps

880 fpm (4.4 m/s)

sink rate at 50 kts

(92 km/h)

, no airbrakes, full flaps

240 fpm (1.2 m/s)

The glide

The glide is defined as unpowered wings-level flight at speed providing best lift over drag ratio

or minimum sink rate.

Should the engine become inoperative in flight, as a result of either intended or unintended actions,

and it cannot be restarted, react as follows:

establish wings-level flight at the speed providing best lift over drag ratio,

if you desire to glide

the greatest distance from a given altitude.

establish wings-level flight at speed providing minimum sink rate

, if you desire do stay airborne

for the longest time. This may come in handy in case you will be forced to give way to other aircraft

or if you simply need time to determine the most appropriate site to land on.

CAUTION:

If the engine fails, especially in climb, the aircraft always loses some 30 meters

(100

feet)

of altitude before reaching best glide speed in wings-level unpowered flight.
