Min horiz speed (Vmin), TOP (ROTAX 914)*, 560Kg ........ 55 km/h (35mph) IAS
Min horizontal speed (Vmin), TOP (912), 500Kg............... 55 km/h (35mph) IAS
Speed for best angle of climb V
X
.......................... 100 -110km/h (60-70mph)IAS
Speed for best rate of climb or maximum endurance V
Y
... 90 km/h (55mph) IAS
Best range speed ........................................................... 130 km/h (80mph) IAS
Long range speed***....................................................... 140 km/h (87mph) IAS
Vmc power-off****............................................................. 32 km/h (20mph) IAS
Vmc power on****................................................................. 0 km/h (0mph) IAS
* Take care! A full power operation at Vmin (especially at a low TOW) with a
Rotax 914UL will result in a very high nose-up attitude with little forward
visibility.
** Long range speed is the speed faster than the best range speed which
results in a slightly lesser range but represents a good compromise between
range and saved air time.
*** Approach speed above 60mph builds energy in the rotor that results in a
long floating landing. Approach speed at 50mph results in a very short
landing roll, and below 50mph requires increasing skill especially at
maxTOW.
****Vmc is the minimum controllability speed. At 20mph or below, engine off,
rudder authority reduces, to negligible below 10mph.
TOP is Take Off Power

5.6 Take-off and Landing Data
Take-offs and landings have been demonstrated up to a crosswind component of 36 km/h.
The following data is valid for operation at a gross mass of 450 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 15m obstacle.
Take-off roll*.....................................................................................80 – 120 m
Take-off distance*......................................................................... 300 m (975ft)
* Take-off roll and take-off distance will be shorter using the boost regime of
the ROTAX 914 engine

Rate of Climb values were identified within noise measurement according to German
regulations and may differ from the listed values depending on engine and propeller type.
