Landing roll .............................................................................. 0 – 20 m (0-65ft)
Landing distance from 15m (still wind) .......................................... 200 m (650ft)
Landings within 100m or less can be made with practice.
The following data is valid for operation at a gross mass of 500 kg at an even air strip with
short grass, no wind, and pre-rotation to 220 RPM. Take-off and landing distances account
for a 15 m obstacle inclusive of a 1.5 safety factor over distances demonstrated in test.
Take-off roll.................................................................. 140 – 220 m (455-715ft)
Take-off distance, 914 UL HTC prop........................................... 460 m (1495ft)
Take-off distance, 914 UL IVO.................................................... 390 m (1267ft)
Take-off distance, 912 ULS HTC prop......................................... 550 m (1787ft)
As an additional information the following data is valid for operation of a Calidus equipped
with an ROTAX 914 UL engine, at a gross mass of 560 kg at an even air strip with short
grass, and pre-rotation to 200 RPM. Take-off distances are to clear a 15 m obstacle,
inclusive of a 1.3 safety factor over distances demonstrated in test.
Take-off roll.................................................................. 160 – 250 m (520-812ft)
Take-off distance, 914 UL HTC prop, pre rotated to 200rpm ....... 685 m (2226ft)
Take-off distance, 914 UL IVO, pre rotated to 320rpm ............. 424m m (1378ft)
Take-off distance, 914 UL IVO, pre rotated to 200rpm ............. 598m m (1445ft)
Typically the fitment of an in-flight variable pitch propeller set to full fine will reduce take-off
distance by 15%, by comparison to the HTC fixed pitch prop, due to the increased static
thrust that is generated.
These distances depend on the aircraft take-off weight and environmental conditions.
Reduced weight reduces take-off distance, and the environmental effects are shown in the
2.2 paragraph. Wet grass or boggy conditions will significantly increase these distances
Crosswind data
Take-offs and landings have been demonstrated up to a crosswind component of 36 km/h
(22mph).
5.7 Influence on Take-off Distance and Climb Rate
All flight performance figures presented in this chapter are based on standard atmospheric
conditions in sea level. Depending on actual temperature and pressure altitude (elevation)
factors on take-off distance and climb rate can be deducted from the following chart.
