Video?? There's video and I missed it??? Drat! Anybody have a link to it?
Please? ) Steve R. "Mike Marron" wrote in message ... If you look at the cockpit video it's obvious that his head is tilted way back watching the horizon while he was inverted prior to initating the Split-S. My primary question is why he didn't abort the Split-S and simply continue the roll at the top of the maneuver and perform an Immelmann instead of pressing on with the Split-S? |

"Nick Coleman" wrote in message ... Without pre-judging this pilot, what happens to a pilot who makes a mistake and totals the aircraft? Out of the team? or out of the AF completely? Nick Last word I have is that he's been transferred down to DC at the Pentagon. It's a desk job for sure if you survive this kind of mistake. But make no mistake yourself in judging Chris Striklin. He's a good pilot. He never would have gotten a slot on the team if he wasn't. He just got caught up in an error. He made a mistake. He was lucky. He's still a good pilot and a fine officer. It's just that you can't make this kind of mistake and remain a Thunderbird. It's impossible. The team has learned something and will move on retaining that knowledge....hopefully using it to good advantage in the future. It's a done deal.

Ummm.... nevermind. I saw the link later while i was reading a different
thread. Thanks though! ) Steve R. "Mike Marron" wrote in message ... "Dudley Henriques" wrote: [snipped for brevity] There's something about this report some of us don't quite get, and it concerns the zero set on the altimeters. The TB fly a zero set altimeter for a show. It's not only basic for low altitude acro work, but it's specified in the regulations for the Thunderbird mission and procedures What puzzles me isn't whether or not he zeroed the altimeter prior to launch or was attempting to convert AGL elevations to MSL altitudes, but rather why he failed to recognize via outside visual cues that he was simply too low to the ground to even THINK about initiating a Split-S maneuver. Clearly, he knew that something was wrong early on since he reportedly exerted "maximum back stick pressure and rolled slightly left to ensure the aircraft would impact away from the crowd should he have to eject." Despite his exceedingly close proximity to the ground the fact that he managed to eject successfully is another indication that he realized quite early on that he done screwed up!

The primary instrument scan is on an ADI which has all the essential flight data for BI. But the altimeter and airspeed are presented as digital information with a "wiper blade" for movement (roughly 2 knot and 20 foot increments ... one sweep = 100 knots or 1000 feet). Not intuitive for the pilot trained to standard instrumentation. We do not have BI-1 check rides. There are backup steam guages ... 2 inch airspeed and altimeter ... that are well out of scan. A partial panel scan is tough. Of course I can dump the system and leave them with a wet compass, a peanut gyro, a clock and the standby pitot statics. Fun to fly a TACAN approach using the alphanumeric bearing to station and DME. Kind of a graduation character building exercise, the Kobiyashi Maru scenario.

Mike Marron wrote in message . ..
Well then, there ya' go!! Here in Florida it's flatter than Sabrina the Teenage Witch but if I flew in mountainous terrain like you I'd roll in the field elevation prior to launch myself. Roger that, I've spent some time running up and down Florida in both F-4s and bugsmashers; not a lot of terrain to hide behind! If I remember right, the highest spot is near Crestview, about 243ft above sea level. Most places you are within the tolerance of the altimeter! (75ft) Anyone who needs two altimeters to shoot an instrument approach has no business flying in the soup in the first place. Airport elevations are clearly depicted on the approach plates and if one is unable to compute his height above the ground after quickly glancing at his altimeter with the correct altimeter setting can expect to auger in exactly like poor ol' Cap'n Stricklin did. Apparently it's a big thing "over there", maybe they were too cheap to buy a radar altimeter? But hey if it works, so be it. Anyone else have experience shooting approaches with QFE set on an altimeter? Furthur, we don't generally (that word again! use cryptic "QFE" or "QNH" catch phrases in the U.S. Instead, simply say "AGL" or "MSL" and you'll less likely be misunderstood since said terminology is the accepted practice here in the U.S. not to mention much more intuitive than those steenkin' European Q-codes are. Standard ICAO terminology (just like these stupid Class B airspaces - I want my TCA's back!). And there is a difference: QFE means setting your altimeter to the kollsman setting that will result in a 0 ft reading at touchdown - NOT "AGL". It's only AGL at touchdown (unless you are flying over a really big pool table...or Florida). QNH is the same as our local altimeter setting, gives pressure altitude, which is approximately MSL altitude until above the transition level, then its only a reference pressure altitude. But you already knew all that, of course. Evidently you still don't understand the problem. The statement above was referring to Stricklin's stunning lapse of judgment that resulted in him attempting to perform a Split-S maneuver despite the fact he was way too low. Oh believe me, I know exactly what the problem is. Doing pops on the bombing range required the exact same figuring of the pull-down and apex altitude, and if you miscalculated or rolled and pulled too low or too tight you would at best drop a lousy bomb and lose some quarters; if you really pooched it you could easily end up dead. Lost some good friends that way. And you absolutely could not depend on visual cues - especially if it was a first look target, and the approach terrain wasn't at the same elevation as the target, etc. You plan the flight, and fly the plan, and if it doesn't look right you abort. Stricklin didn't fly the plan (for whatever reason), then waited a bit too long to abort, that's all. Damn glad he got out! Best of luck there (flying gliders, it'll be a loooong recovery!) No recovery needed or planned, thank you - Racing glass is the only way to fly! Happy aviating, Kirk |

The problem is that the pilots can brief for the right target and then miss it if the concentration is broken. In this incident, the visuals were missed as well. It was a multiple error. It involves broken concentration, and this is the main issue in these accidents. Everyone involved in low altitude work knows that there are multiple cues and what they are. I saw an interesting program on Discovery, or maybe The Learning Channel, a few days ago. It dealt with visual perception. One experiment/example they used was showing a group of people (about 15 or 20) a film of people practicing basketball. The group was told to try to count the number of balls in use. At the end the group was asked if they had seen anything unusual in the film. About 1/4 to 1/3 of the group raised their hands. When they played back the film again it turned out the big majority had just plain not seen a guy in a gorilla suit walk right through the scene. Visual perception depends a lot on what we expect to see, so it is easy to believe that a person could miss the visual cues until it was too late if he was not expecting a problem.
