I could calculate it like I did for Magic 2 if I had some information such as minimum distance where it is unaffected by flare with X rise time when Y distance from target.
Thrust is adjusted to match the flight trajectory charts for only a few data points, the top speed being incorrect by about 100 m/s is offset by rapid early acceleration and the drag coefficient to match a medium alt scenario.
That’s why it underperforms at altitude and over performs at sea level, this is a common issue with many ordnances in the game as we know and this is not a bug.
its already too high
R-27ER now have wrong mass shift, more drag then should be, missing 2000 of total impulse and missing 1.5 g acceleration the result is a missing 80m/s of max speed. it should be 1400ms when now its 1320 at 5000m alt
You are calculating max speed wrong, it’s actually almost exactly 100 m/s less than the speed charts but again, this isn’t a bug. It has been made to match range and time to target data at a specific altitude.
A quick search shows this to be a picture of a frankenstein’s Su-35UB for the movie “Mirror Wars: Reflection One”.
There are many things wrong with the picture, like training and live missiles combined? Unpainted fins on one of the centerline R-27’s? And yes, they do look like the EA seekers.
