YF-22 Skids For A Mile Due To Software Error



In 1981, the United States Air Force pitched a need for an Advanced Tactical Fighter in order to replace the F-15s and F-16s and establish a new air superiority fighter. Six years later, the YF-22 was up in the skies showing what it could do.

As of this writing, there were 195 Raptors produced including the testing prototypes.
well, only 187 aircraft are available in terms of F-22s.

But what people seem to be missing is that he US already has 162 operational F-35 5th generation stealth aircraft flying right now...and the USAF (with 100) and the USMC (with 42) are already at IOC!

By the end of the year, there will be more F-35 operational 5th gen aircraft in the US inventory that F-22s.

...and the beat goes on!

F-22 Raptor Provides Refuge for Honey Bees
192nd Fighter Wing Aircraft Maintainers were bemused when they found a swarm of honey bees hanging from the exhaust nozzle of an F-22 Raptor engine following flight operations at Joint Base Langley-Eustis, Virginia on June 11, 2016.

Initially, everyone's reaction was to run and find someone who could "get rid" of the bees, but Tech. Sgt. Jeffrey Baskin, 192nd Maintenance Squadron crew chief, knew that these honey bees were too important to exterminate.

"I was shocked like everyone else because it looked like a cloud of thousands of bees, but I knew they wouldn't sting anyone and were just looking for a new place to live," said Baskin. "My neighbor maintains two colonies of honey bees and I knew they were at risk for extinction, I figured we might want to get a honey bee expert out to collect them."

Maintainers notified Capt. Katie Chiarantona, 192nd Aircraft Maintenance Officer about the honey bee swarm. Since this had never happened on the flight line before, Chiarantona initially called the on-base entomologist to assess the situation. The entomologist immediately knew that he did not have the means to relocate the bees, so he referred Chiarantona to a local honey bee keeper in Hampton, Virginia.

Andy Westrich, U.S. Navy retired and local bee keeper, arrived on base with the needed materials and supplies. According to Chiarantona, Westrich said the swarm was one of the largest he had ever seen. He was escorted to the aircraft and used vacuum hoses to safely corral the honey bees off of the aircraft into large buckets. He then took the bee's home and found that, as a hive, they weighed eight pounds which calculates to almost 20,000 bees!

"The honey bees most likely came from a much larger bee hive somewhere else on base," said Chief Master Sergeant Gregg Allen, 192nd Maintenance Group Quality Assurance chief, who also happens to be a bee keeper. "Bee hives are constantly growing and they eventually become overcrowded. Around springtime, the bees will make a new queen, scout for a new location and take half of the hive with them to that location."

Westrich suspected that the swarm of bees were on their way to a new location to build a hive for their queen. Queen bees typically fly with eggs to lay at the new hive and do not eat for up to 10 days before leaving to start a new colony. As a result, the queen is often malnourished for the journey. Westrich believes she landed on the F-22 to rest. Honey bees do not leave the queen, so they swarmed around the F-22 and eventually landed there.

According to Chiarantona "[Westrich] said that one out of two things could have happened, the queen would have rested and gained energy and the swarm would've left in the morning, or they would have decided that the jet engine would be a great place to build a hive."

Westrich was able to safely relocate the colony to a local beer producer where they will maintain the honey bee colony and use the honey for their production facility.

"Every bee is important to our food source; lots of things would die without bees," said Baskin. "Most of our crops depend on bees, and our bees need to pollinate. This is why I knew we needed to save them instead of [exterminate] them."

Test Pilots Are The Bravest Out There!

In 1981, the United States Air Force pitched a need for an Advanced Tactical Fighter in order to replace the F-15s and F-16s and establish a new air superiority fighter. Six years later, the YF-22 was up in the skies showing what it could do.

As of this writing, there were 195 Raptors produced including the testing prototypes.

The YF-22 was the prototype that Lockheed came up with. Full of stealth technology and high-tech features, this great looking plane was a thing of the future. It was also extremely dependent on software which ran the whole system as you can imagine, which is what went wrong during the test you’re about to see.

While testing the second prototype in April of 1992, the plane completely took over and the test pilot could do nothing. While approaching the ground, Tom Morgenfeld felt like the plane was dipping so he compensated for it. The computer then took over and you’ll see how that went in the video. That shot from the back was pretty great, as it showed exactly how out of control the elevators were.


Tom definitely saved the day with that FCS induced pitch oscillation, which is why I continually remind people of the difficulty of fully integrating FCS, particularly on the J-20 where the canard is a primary pitch control, in addition to the flapperons. Of course since 1992 we have made some tremendous strides in FCS software/hardware, but it is still highly complex as many control functions are airspeed/attitude/configuration dependant.

The computer does a very fine job of flying the airplane, and the F-22 is a very easy airplane to fly as is the F-35, significantly reducing pilot workload, as in the F-35B.

I would add that we lost an F-22 early on, that had an unscheduled shut down, and was simply restarted without "rebooting" the FCS, I believe that was at Edwards AFB, and the pilot safely ejected, I'll try to research that and refresh my memory.

Those are "position" lights that help you maintain formation in the dark, helps you to maintain a proper sight picture on the orientation of the other aircraft, also for collision avoidance. The F-18 has some very nice "bars" which are displayed and help even more, but on the F-22, everything has been "optimized" for stealth.
 
Yep, its time we sent out a clear message to the bad guys, doesn't matter who they are, let em walk home, or swim. The F-22 has some non-lethal means of waking people up, time we started using them.
do you think Raptors were chosen on purpose, or it just happened to be their watch? (it was bombers they were sent against, some sources say two Su-24s, some other two Su-22s)

The F-22 is always the right bird for this kind of work, those Iranian F-4s had NO CLUE they were in the "Bulls-Eye", until the Raptor jockey gave them a wake up call!

Yes, there is a definite reason the F-22 is doing frequent rotations to Europe, not that anything else in our inventory would be any less effective on the terminal performance end. The F-22 can do all the fun stuff, with relative impugnity, you can't shoot what you can't "paint".
