It probably BS, how can the Ps=0 curve stay outside the max lift curve

That looks like a 9g limiter line from the peak onwards not max lift. Similarly upto the peak could be an AOA limiter line.

Is the chart accurate - pass

I meant the line on the left hand side

The left hand line “up to the peak” could represent an AOA limiter line as it does on F-16 charts.

My bet is something out of a game instruction.

If that's indeed correct (not saying it is), you gotta pull the power back some amount from full AB to 'avoid' accelerating or climbing while on the AOA limiter until you get above 800' and/or below 6G. Big honkin' engines.

Also shows a level 60 degree bank turn at 500 feet and 80 knots if it wasn't for the damn limiter. Now that's a dogfighter. "Why yes, we occasionally come into the break at 140 knots for spacing."

Probably not too useful at 60,000', but should come in handy at the next airshow. What a machine (if it's real).

Over 1000 knots (calibrated or indicated) airspeed at or near sea level? No, that chart is not real. That’s something like Mach 1.75 (assuming kcas) and indicated wouldn’t be much different at very low altitude.

[outlaw162]

That 1000 knots is above 6000'. Hard to tell exactly where but looks to be 8-9000'. Not unreasonable.

And BTW I should have said both above 800' and/or ABOVE 6G earlier.

And also BTW at 9000', assuming were talking KTAS, that's a cal just over 890 and a 1.55 mach.

I believe the right side is turn radius in feet. Altitude says low level. Im off a bit looking at conversion chart now, it’s more like Mach 1.6.

Even with vague altitude as “low level” heating alone would make Mach 1.6 unrealistic except at higher altitude.

[outlaw162]

I'll buy that's turn radius.

Like I was sayin’ — probably part of the kit the comes with someone’s new game.

[outlaw162]

I think I'll just stick to mud-beating discussions. 40 second Boyd would have probably had me in 20 seconds.

The closest thing to a true F-22 EM diagram that I've seen so far, is in this pdf here I found some time ago:
https://www.researchgate.net/publicatio ... g_Aircraft

The guys that did/wrote this, compared their T-68 Saena trainer with the T-38 and the F-22 in a single EM diagram.

According to their diagram, at 15,000ft and at "combat weight", the Raptor has a max ITR of 29.6 deg/s and a max STR of 14 deg/s.
The diagram is in page 76, Figure 70.

The F-22 performance is an estimate obviously lol

With the help of [11] Appendices, we have been able to conservatively estimate F-22 capabilities, and it so appears that Saena could be able to perform the role of a pre-operational trainer at high subsonic, in addition to transonic and low supersonic speeds Figure 69 Note that F-22 has a relatively superior performance at supersonic speeds, a region it has been designed to be operated in.

Well the Iranians are known for their aerospace engineering prowess.
