Probably just the generic info released god knows how long ago.I'm trying to convey to you that this site is lyingNot sure what point you're trying to make. That sheet shows the F-22 having 20,167lbs (9148kg) internal fuel.

Whoops! Fixed in my post. Can we note that I hate the way the new editor handles editing nested comments.
Sounds similar to the loss of the B-2 in Guam, water/moisture in the air data port/probes. In the B-2, the pilot did not turn on the air data port heaters to evaporate the moisture. During flight test and even in the desert, air port heaters were always turned on as part of the preflight checklist.F-22 2020 crash probably caused by smart probe contamination during washing operations:

A $201M maintenance error: Air Force releases cause of F-22 crash at Eglin AFB in 2020
The U.S. Air Force has traced the cause of the 2020 crash of an F-22 Raptor fighter jet at Eglin Air Force Base to a maintenance error.www.nwfdailynews.com
Changing the propulsion system on a fielded aircraft is “extremely complex, and there’s a lot that goes with that,” White said. “So you have to think about what the return on investment might be, there.”
He called out the F-22 as one platform where the directorate is looking at its Pratt & Whitney F119 engines for improvements “and whether or not we’re getting the most out of that system and [whether] we can do more for it.”
“Everything’s on the table” to make improvements on engine performance, regarding “climate, to efficiency, to thrust,” he added, touting a close working relationship with Air Force Life Cycle Management Center’s propulsion directorate.
"It is challenging, even flying the Raptor, to have good [situational awareness] on where the F-35s are," he said.
...
The F-35s "have better detection capabilities kind of against everybody just because of their new radar and the avionics they have," he said. "It definitely adds a level of complexity."
...
"I've flown against red F-35s locally," Bowlds said, telling Insider that "it's always challenging." That challenge is amplified in a large exercise like Red Flag. "There's a lot of different things out there that want to hurt you, and that's where you can start to lose track of the stealth adversaries," he said.

Probably is bright. Like SPF 1000000 bright.One interesting take I saw from that document is that there is a classified store or weapon system available to the F-22. Wondering what it may be....

A very belated update on this; I believe I’ve found evidence that Martin Marietta was the original contractor of the AAR-56. An older article covering the F-22 mission systems stated that the MLD was from Lockheed Martin’s Missiles and Fire Control division in Orlando, FL, which corresponds with Martin Marietta’s Electronics & Missiles Group prior to the company’s merger with Lockheed in 1995.Who were the original developers of some of the key avionics?
APG-77 - Westinghouse/Texas Instruments
ALR-94 - Sanders/General Electric
CIP - Hughes
Who originally developed the AAR-56?
Its already overpowered. Its already the king Kong of air dominance. Money better spent on ngad or b21 or a new icbm or aim260.I am actually surprised at how the USAF never actually tried to upgrade the F-22 by installing some of the F-35 avionics that could help them save a lot of money in the process plus perhaps replacement more powerful engines as well.
Needing to bring back a plane the predates whole lotta love must be equally irritating.Sounds similar to the loss of the B-2 in Guam, water/moisture in the air data port/probes.

Oh gosh... reminds me of that airliner that crashed because some stupid bugs went into the pitot tubes - not properly sealed during a stay on the ground.
This very one...

Birgenair Flight 301 - Wikipedia
en.wikipedia.org
While nobody died in the B-2 and F-22 crashes, stealth aircraft (and particularly those two !) cost US taxpayers an arm, a leg, and a testicle back inthe 2000's .
Plus of course way too few airframes were built (187 and 21, ain't much).
Losing one such precious airframe to such silly mishap... really... must be pretty irritating.
I was going through some older discussions in this thread, and I can’t help but notice, is this Gentex representative Jim Sandberg, the YF-23 PAV-2 test pilot?
Colonel Sandberg flew A-4 Skyhawks in the early 1970s. Graduating from USAFTPS in 1977, he served as operational test pilot in VX-4, Point Mugu, California, flying the A-4, F-4, F-14, and new F-18. He was the 31st pilot to ever fly a Hornet. After leaving active duty in 1982, he worked for Northrop as an engineering test pilot and finally as Director of the F-35 Integrated Test Team at Pax River. A former president of the Society of Experimental Test Pilots, he now works as an independent consultant. One of his clients is GENTEX Corporation, an HMD developer.
Didnt the same thing happen to that B2 that crash?"“maintenance error made after the aircraft was washed” that “impacted control inputs transmitted to the aircraft.”"
Maybe water was where it shouldn't be and affected the air data system?

A confusing mission to inspect the crash site and find the pilot nearly resulted in another collision between an F-22 and an F-35 Lightning II.
@TomS : The pilot would have noted this. It is certainly something that should be part of her/his preflight check.
You'd think the flight control system could do a self-check.@TomS : The pilot would have noted this. It is certainly something that should be part of her/his preflight check.
I always thought what exists a protocol shutdown of the flight computer in case of suspicion critical failure of control systemThe aircraft in fact did give a flight control warning, but the pilot chose to proceed with the mission.
why, I mean Direct lawThe F-22 is a fly by wire airplane. You can't fly it without the computer.
Direct law
Direct law (DIR) introduces a direct stick-to-control surfaces relationship: control surface motion is directly related to the sidestick and rudder pedal motion. The trimmable horizontal stabilizer can only be controlled by the manual trim wheel. All protections are lost, and the maximum deflection of the elevators is limited for each configuration as a function of the current aircraft centre of gravity. This aims to create a compromise between adequate pitch control with a forward C.G. and not-too-sensitive control with an aft C.G.
DIR is entered if there is failure of three inertial reference units or the primary flight computers, faults in two elevators, or flame-out in two engines (on a two-engine aircraft) when the captain's primary flight computer is also inoperable
why, I mean Direct law
the problem was in the wrong sensor data, so turn off automatic response to this data and use control by hands
The B-2 crash was local operating knowledge that failed to get documented in the -1.Didnt the same thing happen to that B2 that crash?
Back to the F-22, it’s interesting that the stick sends a g command above 275 knots and pitch rate command below that airspeed. I recall a test pilot with callsign C-dip (don’t remember his name) who gave a presentation to us UCLA aerospace students at Edwards in 2016 said something similar. He also mentioned that the amount of g that flying the F-22 subjects the pilot to compared to other airplanes is not a pleasant experience.
