rlwicker1967 32 Posted January 23, 2021 Hey Airmen, I was tinkering with the Data.ini and saw MachLimitDry=0.98 for the F-104C. I don't think that should be in there as a limit. The limit for dry thrust should be controlled by Aerodynamics. I tried setting it to 0.58 and, with max Military Thrust, it was held back to 320kts. IMHO, I would think it more realistic to have that setting excluded. I was a real-life pilot and every plane I've flown had the equivalent of a Barber Pole to indicate Vne. I will have to check the stock aircraft for that as I suspect that could be the source of some of the speed problems. I tried \\ to take it out and the difference is amazing. That removes the aerodynamic brick wall phenomena for sure. 1 Share this post Link to post Share on other sites

+logan4 847 Posted January 23, 2021 Actually the 0,98 is quite close to what the bird can do in dry mode, though altitude dependent. The pic is from an F-104S flight manual, remember it shows a clean AC performance data. Share this post Link to post Share on other sites

The pic is from an F-104S flight manual, remember it shows a clean AC performance data. I get this but, that parameter is for the straight and level max speed with dry thrust. What I'm talking about is when you start going downhill. If you're at FL400 and Mach 0.96, you should be able to get supersonic without afterburners until the air gets too thick and the drag becomes significant. I remember in WoV, going nose-down in an F-4 at full AB, getting supersonic, and the speed reducing dramatically when going to dry thrust. What I'm saying is, the limit should be based on aero and not some system controlled parameter. I get the terminal velocity issue. That MachDryLimit has nothing to do with that.

+logan4 847 Posted January 25, 2021 I do understand where you want to go with it, but on my experience you can go supersonic in this game easily in a 35-40 degree dive while the throttle is set to 0%. Not sure your game setup and the plane set you got, the pic is from a stock F16 which have machlimit 0,98 in the data.ini. As you can see it can hit 1,11 actually was 1,12 just missed the point as started to get bellow 4500m and the air started to slow it down. With an other AC that has no dry limits set I got 1,24, on an other that has 1,14 for limit in the data.ini it reached 1,32 under the "same" conditions (starting at 42kft, 0,96M, no throttle, 1-1 IRMs on wings, 35-40deg dive). And bellow 4500 you really start to feel the effect of the slowing, by ground level speed was bellow 0,96 or less - still no input from the engine(s). On a personal note, the parameter might have something to do with supercruise capability simulation/integration into the game. 1 Share this post Link to post Share on other sites
