6 Performance
6.1 General
This section contains performance data of A-22LS airplane of standard (basic)
configuration at maximum takeoff weight in the following environmental conditions: ICAO
standard atmosphere (ISA), mean sea level (MSL), no wind, hard and even runway. Those
data may vary depending upon the configuration and technical condition of a particular
aircraft and actual environmental conditions of its operation.
6.2 Takeoff and landing distances
The minimum takeoff and landing distances of A-22LS for the above conditions are
specified below. However pilots should always keep in mind that actual takeoff and landing
distances depend on condition of the aircraft, environment and pilot skill.
Engine
Rotax-912UL
Rotax-912ULS
Takeoff run
140 m (460 ft)
105 m (344 ft)
Landing run
185 m (607 ft)
185 m (607 ft)
Takeoff distance to 15 m (50 ft)
405 m (1329 ft)
335 m (1100 ft)
Landing distance from 15 m (50 ft)
440 m (1445 ft)
440 m (1445 ft)
6.3 Climb performance
The rate of climb depends on atmospheric conditions, airplane takeoff weight and flap
setting. The climb performance data of A-22LS in ISA conditions at MSL, maximum takeoff
weight are specified below:
Engine
Rotax-912UL
Rotax-912ULS
Best angle of climb speed V

90 km/h (56 mph, 49 kts)
90 km/h (56 mph, 49 kts)
Best rate of climb speed V
Y
100 km/h (62 mph, 54 kts) 100 km/h (62 mph, 54 kts)
Maximum rate of climb at V
X
2.3 m/s (453 fpm)
3.2 m/s (630 fpm)
Maximum rate of climb at V
Y
2.6 m/s (512 fpm)
4 m/s (787 fpm)
6.4 Cruise speeds and fuel consumption at various RPM settings
The cruise speeds and fuel consumption depend upon a multitude of factors: propeller pitch
and engine adjustments, fuel quality, atmospheric conditions, flight altitude, aircraft loading
and condition of its outer surface, etc.
With the KievProp three-blade propeller adjusted to take-off RPM of 5100 per minute and
standard condition of atmosphere and aircraft the following cruise speeds and fuel
consumption values may be used for flight planning:
RPM Cruise speed, IAS
Fuel consumption, US gal/h
400
0
110 km/h (68 mph, 59 kts)
10 l/h (2.6 US gal/h)
460
0
148 km/h (92 mph, 80 kts)
15 l/h (3.9 US gal/h)
