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

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:

Maximum rate of climb at V
Y
2.6 m/s (512 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
4000 110 km/h (68 mph, 59 kts)
10 l/h (2.6 US gal/h)
4600 148 km/h (92 mph, 80 kts)
15 l/h (3.9 US gal/h)
5000 161 km/h (100 mph, 87kts)
19 l/h (5.0 US gal/h)
5400 180 km/h (112 mph, 97 kts)
25 l/h (6.6 US gal/h)
