Let's say an F-104 Starfighter is flying at sea level at 600 KIAS with throttle at 100% RPM.
Then, let's say the F-104 is still flying at sea level, but the pilot reduces throttle and airspeed falls to 250 KIAS. The pilot then pushes the throttle to 100% RPM and starts accelerating.
My question is, at 100% RPM, will fuel consumption be greater at 250 KIAS and less at 600 KIAS?
Does airspeed impact fuel consumption? The higher the airspeed, the less fuel consumption, and the lower the airspeed the greater the fuel consumption?
