Flight duration of Bf 109 F-2

[Jan Bobek]

I would appreciate your comments on following topic:

If Bf 109 F-2 (DB 601 N engine) flew a mission with duration about 1 hour and 25 minutes, does it mean that it was equipped with auxiliary fuel tank?
Or was it a flight at limit of consumption from ordinary fuselage tank?

I undestand that this is tricky question, since fuel consumption depends on many conditions during flight.

Theoretically Bf 109 F-2 should have range 650 km at average speed 528 km/h.

Not necessarily since it depends on the wind conditions and the power setting used. When using dauerlestung with manual overide of the prop pitch it was possible to achieve quite long ferry flight w/o any droptank.
