5.3.12 Maximum Endurance and Range
• Useable-fuel
17.2 US gal / 65 l
33.5 US gal / 127 l (with
The maximum endurance (without reserves) is only valid for the useable fuel
(depending on A/C-equipment) and when the aircraft is fuelled optimally.
When making errors while fueling the A/C (for example: A/C is not horizontal,
A/C is parked on a sloped surface, or similar) changes of up to ±5% in the
maximum amount of fuel can occur.
The minimum non-useable fuel in the right wing-tank (standard) is 0.55 US gal /
2.1 l. In the left wing-tank (optional) it is 0.3 US gal / 1 l.
To determine the approximate endurance with tanks completely filled (without
reserve), follow this method:
Standard 16.6 gal / 63 l : 5.4 gal/h / 20.4 l/h = 3.08 h
With optional tank 33.5 gal / 127 l : 5.4 gal/h / 20.4 l/h = 6.22 h
Available flight-time ≈ max. flight-time (from table or graph) multiplied
with amount of useable fuel divided by max. amount of useable fuel.
Calculate the range without reserves approximately by using the available
endurance and the true air-speed.
Standard 3.08 h x 97kts / 180km/h = 300 nm / 554.4 km
With optional tank 6.22 h x 97kts / 180km/h = 604.5 nm / 1119.6 km
