When Will Gaijin Address The F-5A/C's Unrealistically Cold Engines? Video included

Oh really? I thought there was a few about the cold engines

I searched before making the thread

That’s my bad, but still, I doubt they will because F-5C is still selling pretty well

I’m sure it still would with non-broken engine temps

Might lose them a pound a year

Its the exact opposite issue to the Harriers.

Thrust = exhaust temp

Where the Harriers have a lot of thrust and therefore are hot. The F-5s appear to have very little thrust and so are cold.

F-5s are actually colder on AB than an F-117 btw:

So I wonder if the same potential solution could work for them. Use the F-117 code but instead of it being 0.5x multiplier, I wonder they could be given the reverse, such as a 1.5x Multiplier

Its discussed a lot, but I dont think there is a specific thread for just it.

It’s obvious when you play at this BR, or alternatively just watch the new video I attached to the OP just now

Yup, the amount of times that I’ve had an Aim-9L and been unable to get a front aspect lock is actually quite rediculous

Their code must be bigly messed up because frontal aspect shouldn’t even be linked to engine heat

Commenting in support before this gets locked randomly

the code used for F117 should be utilised to rework a lot of aircraft

such as?

The way I vaguely understand it, is that thrust = temp. Exhaust direction and temp is not modeled at all on fixed wing aircraft. So using the thrust output as the IR signature figure is actually quite a clever way to avoid having individually model IR signatures for every aircraft, because not only does this roughly approximate how things should be (more thrust should mean bigger engine and therefore more temp) but it also varies based upon engine output.

and in 99% of cases, I think its actually quite a clever shortcut which worked, for a time. I think its now showing its shortcomings, with both IR vs helis and edge cases like th Harrier and F-5.

Yep, could be a perfect short-term bodge for a lot of aircraft

Harrier which is too hot, F5 which is too cold. can use the radar stealth side to correct RCS on aircraft which are funky too

All Harriers are really hot (at 420kts, it takes 8+ flares to defeat a rear-aspect R-60M at 3km)
All F-5s (and I think the F-20) are really cold
F-14s I think are struggling a bit with being too hot.
Gripens and the BOL strength problems I think was exasperated by being a fairly cold airframe

What’s funny is that they don’t even produce that much thrust compared to other stuff they regularily meet. I’ve noticed that the Yak-38 has a really high heat sig too, so it might be something to do with VTOL aircraft in general.

Back to the F-5s, they show Gaijins issue with modelling thrust=heat signature very clearly. The only other planes that you see such low heat signatures with, are from AI planes.

There is definetly an “X” factor that also comes into this, but I have no idea what that is.

Would be really good to get a dev-blog on how IR signatures are modeled in game at some point.

F-5 also massively overperforms in STR as its wing efficiency is much too high.
