9. PERFORMANCE
9.1 General
The performance data in the following section has been computed from actual flight tests with the ultralight
and power plant in good condition and using average piloting techniques. It should be noted that piloting
techniques, climatic conditions and ultralight condition will cause significant variation to these performance
figures.
9.2 Take Off and Landing
Take off and landing distances are specified for maximum take off weight of the ultralight
Take Off
Take off Distance to 15 m altitude is 245m.
Takeoff distance is specified for elevation at the sea level with maximum take off power, a level dry runway with
short grass, zero wind conditions and air temperature 15 deg C
There are following factors which will increase takeoff distance:
- Reduced power take off;
- Higher drag runway surfaces such as wet or long grass;
- Tail wind;
- Uphill takeoff;
- Air temperature above 15 deg C;
- Runway elevation above sea level;
The pilot is required to take into account the effect of the above when determining takeoff distance.
Landing
Landing Distance from 15 m altitude is 300m.
Landing distances are specified for elevation at the sea level with maximum take off power, a level dry runway
with short grass, zero wind conditions and air temperature 15 deg C.
The following factors will increase landing distance:
- Lower drag runway surfaces;
- Tail wind;
- Down hill landing;
- Air temperature above 15 deg C;
- Runway altitude above sea level.
The pilot is required to take into account the effect of the above when determining landing distance.
Always exercise judgment when selecting locations for take-off and landing. Leave adequate
margin for appropriate control action in the event of sudden engine failure or turbulence being
encountered.
9.3 Climb
Climb rate with maximum take off weight at 80 km/h is 4.2 m/sec
.
Climb data is given at sea level elevation and
15 deg C.
9.4 Stall Speeds
Stall speed at maximum take off weight is 56 km/h.
Stall speed at 320kg take off weight is 52km/h.
9.5 Glide
Glide figures have been determined with the engine off at maximum take off weight with the trim device set in
the take-off configuration.
At 80km/h the descent rate is 2,8 m/sec.
