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.
Takeoff/Landing run ............................................. 100 m (328 ft.)
Takeoff/Landing distance to/from 15 m (50 ft.) .... 243 m (797 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:
Best angle of climb speed V
X
............... 90 km/h (56 mph, 49 kts)
Best rate of climb speed V
Y
............... 100 km/h (62 mph, 54 kts)
Maximum rate of climb at V
X
............................ 3.3 m/s (650 fpm)
Maximum rate of climb at V
Y
............................ 3.5 m/s (690 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)
However these values should be considered as approximate as they may vary due to
effect of the above mentioned factors. It is recommended to verify those values for the
particular conditions in which the exact values are required.
