Sink Rate and Glide Ratio
The sink rate depending on airspeed with the engine in idle is plotted in the following
diagram:
At 560Kg MTOW expect a sink rate of 1050fpm at 35KIAS, 1200 at 43KIAS, 1120 at
52KIAS, 1320 at 61KIAS, 1550 at 70KIAS, and 1600 at 78KIAS.
In case of an engine failure at 560Kg MTOW, expect a glide ratio of 1:3 which corresponds
to a vertical distance of 900 m or 0.5 nautical miles for each 1000 ft.

Additional Performance Data
5.9.1
Fuel Flow
The following fuel flow figures are provided as estimates and do not constitute certified
performance. Exact fuel flow will vary with environmental conditions, cleanliness of propeller
and rotor, piloting technique (minimum side slip), and power setting. For additional
procedures about proper power setting consult SECTION 9 for supplemental data
concerning the variable pitch propeller.
Fuel flow at 68 KIAS, 500Kg TOW...........................................................15 ltr/h
Fuel flow at 75 KIAS, 500Kg TOW...........................................................18 ltr/h
