De Havilland DHC-1 Chipmunk for X-Plane 10 by Khamsin
Flight manual
OPERATING DATA
1 Take-off
At the maximum weight of 2,1001b., using half flap, the approximate take-off distances (in yards) in ISA conditions, zero wind, are as follows:
| _ | Runway | Grass |
| Ground run | 220 | 245 |
| To 50 ft. | 450 | 485 |
According to airtield and AUW conditions, these distances will be affected as follows:
- Each 1,000 feet increase in altitude increases the distance by 7.5%.
- Each 10°C rise in temperature above ISA increases the distance by 5%.
- Each 100 lb. decrease in AUW decreases the distance by 10%.
- Each 10 knot increase in headwind decreases the distance by 22%.
2 Climb
At a take-off weight of 2,100lb. and at a speed of 65 knots. the sea level rate of climb in ISA conditions is 840 ft./min., reducing by 45 ft./min. with each 1,000 feet of altitude.
The rate of climb is reduced by 15 ft./min. for each 10°c increase in temperature above ISA and is increased by 40 ft./min. for each 100lb. reduction in AUW.
The fuel used for take-off and climb to 10,000 feet is approximately five gallons.
3 Cruise
Range and endurance
- The recommended range speed is 90 knots at all heights.
- The optimum endurance speed is 60 to 65 knots.
