[NO BUG] Can't attain 9.0g at corner speed

The corner speed for the F-16 is in the range of 330 to 440 kts.

At sea level on a standard day, the F-16 should reach 9g at mach 0.67 (right about 440 kts).

In DCS, at M 0.67 the jet only pulls a maximum of ~8.7g with full joystick deflection.

The g buildup is also pretty slow, an initial pull only reaches 8.2-8.3g before the airpseed starts to be too low to allow pulling maximum g, for this reason (not necessarily a problem/bug), in order to reach 8.7g I have to start the pull above the 440kts, at which point the peak g is 8.7 down to 440kts, where it will start to decrease.

I have checked the EM charts available from various sources.

just made a test 60% fuel for a total of 24489 lbs, sea level

same result as you, max 8.7 g's

Just to confirm...CAT 1 right? and no TGP or other ordnance..

CAT1 of course, no external loads.

They did specify M0.67, and they're saying the g-onset is too slow to be able to reach 9g under those circumstances. This is 60kts less than you've done your test at (60kts/0.1M)

I suggest asking the SMEs about technique in this case, as a lot of misconceptions arise from lack of knowing technique.

Ie. is the g onset really slow enough to cause this - what airspeed do they prefer to pull from, where do they max out etc.

Ok here.

 

You're at M 0.76 and 462 Knots...

I'll provide a track but please pay attention to the details before labeling something as CANNOT REPRODUCE. Of course you can't if you follow the wrong parameters.

Thanks

Hi everyone,

 

For a sustained 9G pull the aircraft needs to be at least 450/460 kts. You should not be able tor sustain 9G below this. It would be a bug to sustain 9G at only 440 kts. At 440 kts, you should expect a sustained G of 8.8 to 8.9.

 

This is based on get getting off the phone with a 4k+ hour Viper pilot.

 

Thanks

That's great, thanks for the input.

Anyway I was not referring to the sustained turn, but instantaneous load (fully aware this is transient and can't be sustained at 440 kts).

However, I re-checked the mission file I used and the aircraft had more fuel than I had wanted to set-up (probably a slip of the mouse).

Tried again at 22000 lbs GW, and it seems more in line, reaching 8.9 at 440 kts :thumbup:

P.S. man, you started your post with "hi everyone" and now I can't get your voice out of my head :D

Wow - this is literally going the extra mile to satisfy a simmer's curiosity here - going right to the source; can't really top that. Thanks Wags! :thumbup:
