The following table contains te<strong>ch</strong>nical data about fuel consumption<br />
and maximum range for the constant speed propeller. Manifold<br />
pressure shall serve as advice only. It is acceptable to <strong>ch</strong>oose the<br />
power setting “Full Throttle” over the total engine speed range (see<br />
also Rotax-Manual). However for economic reasons is advised to<br />
adhere to the following table.<br />

All values related to the 22 gallon fuel tank system (21 gallons usable), within the<br />
ICAO standard atmosphere.<br />
(*) Not for ASTM aircrafts certified in USA<br />
Comment:<br />
Flight performances can vary significantly due to tolerances of<br />
propeller and engine, flights without doors, deviations from<br />
temperature and air density from standard ISA conditions, etc.<br />
