Fromflorida Posted October 3, 2023 Share Posted October 3, 2023 When I take off, I am not getting full speed in the F/A18. When I'm in flight, I average a speed of 200 mph. Other aircraft have the same issue. Link to comment Share on other sites More sharing options...
Mike80 Posted October 3, 2023 Share Posted October 3, 2023 What simulator ?? "Full SPEED" - indicated or True airspeed?? "MPH" - why, how? an F-18 uses knots - where are you using this; also for an F-18, what altitude are you talking about? Link to comment Share on other sites More sharing options...

This can be further obfuscated when TAS and IAS are referenced, but not explicitly designated, in the same article (this might be the OP's issue).

jgf Posted October 3, 2023 Share Posted October 3, 2023 But not everyone here has military background. And you will find plenty of online data for military aircraft giving specs in mph. It may not be technically correct but it is not wrong. Link to comment Share on other sites More sharing options...
ViperPilot2 Posted October 3, 2023 Share Posted October 3, 2023 Question to the OP... Which one are you flying? Who made it? I have the KBT Super Hornet for FS9, and the last thing I'd call it is a 'slow' Airplane. I don't even have to use AB, and she's off the Runway (5,800' MSL) at 170 KIAS and accelerating like the proverbial bat out of The Hot Place; @ 10K MSL I'm already past 250 and still punching a hole in the sky. If I'm not paying attention I get into an Overspeed condition in a jiffy.

And most of it is generalized for public consumption, often inaccurate or plain wrong. However, I will add that in the WWII era and before many military planes did use mph vice knots. You will also note that US navigation data is in knots because it has a direct physical meaning: 1 nm =1 minute of latitude Link to comment Share on other sites More sharing options...

When I'm in flight, I average a speed of 200 mph. Other aircraft have the same issue. That several aircraft have the problem indicates that it is probably some setting causing the problem. If you Google the problem, you will find plenty of suggestions such as to check null zones, to check to see if you have duplicate bindings in your control settings or even to check if you have 'Assisted Take off' engaged as that can over ride throttle settings. Run your engines to full power on the ground to see if you get the required max RPM (or 100% power in TBM 930) - this may indicate if your throttle is not giving you full power and hence not getting you up to speed when airborne.

snave Posted October 9, 2023 Share Posted October 9, 2023 I'll mention that MACH is more important then MPH or Knots at altitude. Our OP should confirm he is aware of the difference, whereupon I'll expand...? Link to comment Share on other sites More sharing options...
