Fuel Flow Versus Altitude

[IvanK]

Is Fuel Flow reducing with Altitude modelled in Lock On..? as far as I can make out its not.

Actually yes it is. IIRC I even have a fuel flow chart for the F-15 somewhere around here that a squadmate of mine made ... I also have a utility that will in fact show you fuel flow on a G-15.

 

You will certainly burn less fuel at high altitude while maintaining the same *ground speed* as that at low altitude. IAS drops, and so does fuel consumption - for a given RPM setting on the engines.

 

The drop is not terribly much, and it is linear.

 

Here is an example of some data I collected:

Great stuff good looking data.
