5.3 ADDITIONAL INFORMATION
5.3.1 Cruise.
This Section is provided By JABIRU for information purposes. It is not CASA Approved
The JABIRU 220 engine has an altitude compensating carburettor which ensures that the fuel
flow is constant at all operating altitudes. This feature has been examined by flight testing, and
verified for altitudes between sea level and 5000 ft.

NOTE
The JABIRU 2200 engine has an altitude compensating carburettor which provides for a
fuel flow that is constant at all operating altitudes. This feature has been examined by
flight testing, and verified for altitudes between sea level and 5000 ft. Fuel flow values
have not been verified above 5,000 ft therefore pilots will need to monitor fuel flows to
ensure accuracy when operating above that altitude.
For flight planning purposes when the flight is above 5,000 ft, pilots should program a fuel
burn which is for the next highest rpm range in the table above.
5.3.2 Endurance
This Section is provided By JABIRU for information purposes. It is not CASA Approved
Aircraft endurance can be calculated using the information presented in paragraph 5.3.1 “Cruise”
above. When calculating endurance, an allowance should be made for engine start, taxi, take-off
and climb. IN normal circumstances a total allowance of 5-litres for these would be adequate.
This allowance should be subtracted from the actual fuel on board prior to flight. i.e.
Fuel on Board – Allowance = Fuel assumed for endurance calculations.
