Any Cause Info on Blue's Crash?

[splatt]

From the link regarding G-LOC posted above...

G-LOC as a causal factor in the loss of many high performance military aircraft.

Surveys show a proportion of G-LOC incidents, including some at Gz levels of 4G and below, have occurred in low performance training aircraft as well as high performance aircraft.

Centrifuge studies have supported the results of these surveys.

The US Naval Aerospace medical Research Laboratory suggested to the Bureau that in such aircraft, the greatest danger may occur in manoeuvres which subject a pilot to negative Gz just before exposure to a high rate of onset of positive Gz. Negative Gz sustained for more than a few seconds will initiate a slowing of the heart rate, and this will markedly reduce positive Gz tolerance if the positive Gz exposure immediately follows the negative Gz.​

BeeVee-

You said that you read that info in the safety report? The privileged one? Are you sure you want to publish any details that you got from that report on a public website?

Reconsider, my friend.

There are plenty of parts of the SIR that are not privileged and available for public consumption. In fact most of Part A is non-privileged.

Lighten up, my friend.

First, I'm not a Hornet pilot. Second, I have no Safety School credentials.
At that point in their profile, #6 is joining the delta with about 90 degrees of aspect and heading crossing angle, and doing about 420+. Squating the jet for that rejoin (sorry, "rendezvous") means about 7.5G's coming on quickly. Very quickly. And if he's upwards of around 480, my Hornet buds tell me the jet will go quickly to about 8.1Gs.

Hornet won't exceed 7.5 unless you over ride the G-limiter (or you yank, either way it's an over stress)... Hornet also bleeds like a stuck pig at 7.5 and can't sustain it very long unless in the vertical. Doesn't mean everything else you said isn't applicable though...

There is video of this crash? Can someone post a link?

 

[MJG]

The video only shows the aircraft joining back up with a hard turn and then disappearing behind the tree line, it's from a very far distance away so you really don't see much.

Search Youtube.

Thanks for the info; I didn't realize it was limited to 7.5.

I wish you success!

Here's the release. Like the word going around the squadron, controlled flight into terrain.

A quote from the Pensacola News Journal article stating the cause:


failure to perform a proper anti-G straining maneuver resulted in him suffering possible physiological effects that contributed to his loss of situational awareness of his rate of decent and ultimately a controlled flight into the terrain," the report states.


Davis didn't black out from excessive Gs, Hanzlik said.

"In this particular case, Davis still had input on the aircraft. The onboard flight data recorders showed that there was still pressure on the flight controls. If he had been blacked out, then he would have completely released the flight controls."

Guadagnini said Davis "was trying to fly all the way down."

"We have evidence that he attempted to recover from the impact and regain situational awareness," he said.
