Spitfire Question

The guage is showing the contents of the bottom tank which is continually being topped up by the top tank. So until the the top tank is emptied the bottom tank is full.


Cheers!

Top tank 48 gal lower tank 37 gal, totally 85 gal, fuel consumption full power approx 80 gph, cruise regime approx 35 gph. Unlike Hurricane, there is no switch modelled in order to switch the dial to upper tank, hope it will come one day.

Also note that hurrricane has a dial switch and a reserve tank, both left & right are sumped together as main tank in the Hurri, no such design in a Spit.

Fuel consumption Spitfire II PNs although they only specify maximum rpm and boost.


Later Spitfire PNs were much better at giving fuel consumption for several engine settings: Mk VII and VIII PNs

Hi

I gave values from measurement, they actually differ from game to manual. As far as I remember you get 85 gph rich full power and 35 gph lean at cruise 200 TAS (not IAS).

That's about what I'm getting: 35 gph, lean = 12,000 ft @ 1,700-1,725 rpm, 200-210 mph, radiator shutter half closed coolant 86-90°C oil 82°C.
