5.8 Sink Rate and Glide Ratio
The sink rate depending on airspeed with the engine in idle is plotted in the following
diagram:
In case of an engine failure, 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.
5.9 Additional Performance Data
5.9.1 Fuel Flow
The following fuel flow figures are provided as estimates at nominal aircraft loading and do
not constitute certified performance. Exact fuel flow will vary with engine choice, operating
weight, 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, if
installed.
See also the Rotax Operators manual, which shows engine fuel consumption at different
power settings.
Fuel flow at 130 km/h (80mph) IAS, level flight ................................... 13-15ltr/h
Fuel flow at 160 km/h (100mph) IAS, level flight ......................................18 ltr/h
