Thanks for the detailed explanation. I am trying to find the limitations imposed on the various aircraft I fly. Guess I should invest in a stop watch. Smile

Now I know that the cowl flaps control in the game opens both the cowl flaps and the radiator/oil cooler flaps. On the real aircraft these could be operated independently. I created a mission using the Solomons October 1943 and I set the date of October 1, 1943. I took off from Barakoma in a F4U-1A Corsair and noted that after attaining the top level speed at the normal power condition of 44" MAP.2550 RPM I went to War Emergency Power (110% Water Injection and 2700 RPM) with the cowl flaps/radiator closed the first temperature to reach its limit was the oil. If I could have opened just the intercooler flaps independently I could have delayed this for a brief period of time as I passed 350 MPH.

Is there any possibility that in the future the cowl flaps (Cylinder Head Temperature Control) and inter-cooler flaps (Carburetor Air Temperature Control ) and oil cooler flaps (Oil Cooler Temperature Control) operation can be made to be operated separately instead of all three opening together all of the time. Only the appropriate cooling flaps would be opened for a specific heat issue among other solutions. This is explained in the "Pilot's Handbook of Flight Operating Instructions For Naval Models F4U-1 F4U-1C F4U-1D F3A-1 F3A-1D FG-1 FG-1D Airplanes British Models Corsair I.II.III.IV" I also think there is a speed limitation for opening the cowl flaps and would reduce the drag hit from having all cooling flaps open when it isn't necessary. The F6F-5 also had the cowl, inter-rcooler & oil cooler flaps controlled separately. The F6F-3 had the cowl flaps controlled separately while the inter-cooler & oil cooler flaps operated together. Information about the F6F 3 & 5 came from "Pilot's Handbook of flight Operating Instructions for Navy Models F6F-3, F6F-3N, F6F-5, F6F-5N Airplanes".

On the American birds we have the mixture choice of Auto-rich or Full-rich, (Wish we had Lean and Auto-lean for flights from Guadalcanal to Bougainville). Using Full-rich above 2,000 feet leads to lower power and black exhaust smoke. Under what circumstances does Full Rich help? Takeoff in an overload condition? Combat below 2,000 feet? According to "Pilot's Handbook of Flight Operating Instructions For Naval Models F4U-1 F4U-1C F4U-1D F3A-1 F3A-1D FG-1 FG-1D Airplanes British Models Corsair I.II.III.IV" the mixture control had three preset conditions: Auto Rich, Auto Lean and Idle Cutoff. The Full Rich position having been eliminated.
