Yes!..this is the true speed…

That’s not even the point of what I said… read again

It’s 50% of normal fuel load not 50% of maximum fuel

you said the missile followed the wrong path off the rail and would have hit the jet otherwise
that’s wrong, had the missile been launched slightly later and not locked on/gotten fooled by flares, it would have turned harder off the rail and probably could have hit the jet

Is there any quote on the document saying that? To me it looks like it is equivalent airspeed.

This is 50%(half)refueling of fuel in internal tanks…

Velocity is indicated airspeed

Manual specifies in the introduction that velocity should be assumed to be indicated unless states otherwise as posted above, so it is IAS not TAS

This now makes sense and renders the comparation posted above as wrong

In-game at 30 minutes fuel it is already doing ~14.65 deg/s prior to the Oswald efficiency buff. Now that it has a cockpit WTRTI will track the data properly so when dev server opens next we can test again. What I saw was that its’ sustained turn rate was already for the most part correct (and superior to the F-15s).

The F-15 when testing had underperforming sustained turn rate below 0.4 mach airspeeds (by like 0.5-1G)… However, at speeds 0.4 mach + it was performing pretty much identical to the charts.

This whole discussion is based on a line from the Russian documentation claiming as much as 5 deg/s difference which is nothing short of absurd. I don’t see where / how this is the case.

this should be the initial trajectory of the missile, taking into account the position of the nose at the moment it fired

but in reality the missile goes in a totally different direction from where the nose of the plane is pointing


thats my point, the missile should not go down like that when you are pointing your nose almost direct at the other plane, like i said for @MiG_23M - it seems that the pitch up it’s so sudden that the game still thinks the plane is in the initial position before he pulled full AoA to lead the missile

i also pointed out another example here comparing to how it is in DCS

this is for the document of this graph right?

Spoiler

The graph is from the TsAGI report and is seems to be a clean Su27 with 18920kg gross weight (50% normal fuel load

Edit: Looks like not a clean configuration as the same 3000m curve is much lower than that in the 27SK manual.

Not in all documents…In this case, the instrument speed is indicated separately…It is also fully written-true/instrument speed…

13 min roughly equals to 50% normal fuel loading. I guess it’s used for testing by the devs.

if it is indicated, it is much closer.
Also 3000m is a bit lower than 10000 feet and 35000lb is around 60% internal fuel on F-15.

No!..see my post below and read carefully … in this book (this is not the RLE Su-27SK)-THE INSTRUMENT AND TRUE SPEED ARE DUPLICATED BY TEXT AND FORMULA…The charts show the true speed.I underlined the text and the number of the graph drawing…

In this table, it is incorrect for the Su-27…
