Performance
Introduction
This section provides information on aircraft’s airspeed calibration, stall speeds and general perfor-
mance. All data published was obtained from test flight analysis using average flying skills.
Sinus 912 LSA 80/100 has demonstrated adequate engine cooling performance at ambient tempera-
tures of 38 Celsius / 100°F. This is not to be regarded as the limit temperature, however temperatures
higher than the mentioned may have adverse effects on engine cooling and overall performance.
Airspeed indicator calibration
(IAS to CAS)
Pitot tube’s mounting point and construction makes IAS to CAS correction values insignificant.
Therefore pilots should regard IAS to be same as CAS.
IAS = CAS.
Stall speeds
Stall speeds at MTOM (1210 lbs, 550 kg) for all models of Sinus 912 LSA are as follows:
flaps in negative position; -5° (up):
44 kts
(81 km/h)
flaps in neutral position; 0° (neutral):
40 kts
(74 km/h)
flaps in 1
st
position; +9° (down):
38 kts
(70 km/h)
flaps in 2
nd
position: +19° (down):
34 kts
(64 km/h)
Take-off performance
All data published in this section was obtained under following conditions:
aircraft at MTOM
elevation: sea level
wind: calm
runway: hard runway
Data extrapolated for ICAO standard atmosphere

takeoff ground roll at MTOM
430 ft
(132 m)
takeoff runway length (over 50 ft/15m obstacle)
760 ft
(232 m)
Notes
In order to meet the data for takeoff runway length over 50 m obstacle maintain Vx after
take-off.
Soft (grass) runways increase the published take-off performance data by 20%.
Takeoff runway length may vary depending on the wind, temperature, elevation and
wing & propeller surface condition.
