5 Performance
All performance figures are based on airplane weight of 660 kg, standard atmospheric conditions,
level, hard-surfaced dry runways and no wind. They are estimated values derived from flight tests
conducted by Pelegrin Ltd. under carefully documented conditions and will vary with individual
airplanes and numerous factors affecting flight performance.

Takeoff Distance (m)
Distances stated are valid at sea level and MTOW 660 kg, equipped with EPA Power SA-R917Ti
engine and Neuform Propeller.
•
Decrease distances by 10% for each 7KT headwind. Increase distance by 10% for each 1.5KT
tailwind.
•
Decrease distances by 7% for each 10°C below ISA. Increase distance by 8% for each 10°C
above ISA.
•
Increase distance by 10% for each 1000 FT of field elevation above MSL.

Takeoff Speed
A standard, calculated takeoff condition with flaps deflected in position 1 has been considered in
this graph. Under actual conditions Takeoff (Liftoff) Speeds can be 10-12% lower.
