JJ,
The finish cylinder has its place in competition. But not to the exclusion of the finish line. Many of us still contend that it is better to race to a visible marker rather than to a virtual point in space requiring refernce to instruments. Heads up rather than heads down. As for the FARs, aircraft regularly take off and land withn 500 feet of people, structures, and other aircraft at commercial airports. This is by necessity. An airport manager must balance proactive safety initiatives with perceived risk versus safety history. And finally, trailers and tie downs are mobile. Are we there to race or to recreate? If the latter, call it a camp and dispense with the racing altogether. Camps are fun too, but let's not confuse them with contests. OC |

Our barn has that gray grungy look that old wood gets, so I have been
power-washing it in preparation for a coat of clear Urethane. Now power washing is a monotonous task, so I started thinking about Finish Line Accidents. Surely we must have had some, then, way up at the top of my 20 foot ladder, I remembered ONE. Uvalde, August, 1986. It was the first Nationals at Uvalde, 15 meter I think Anyway, this ASW-20 driver hit the Finish Line, low and fast (in those days, 5 feet was OK) He then pulled up and proceeded off the airport to the North and crashed in a housing area. KS remembers, we helped remove the wreckage from this guys pick-up truck and front yard. Pilot was severely injured, but recovered satisfactorily. It was widely suspected that the pilot was suffering from dehydration. So, not a Finish Line Accident, just a medical condition, Right? Dr. Cannon has lectured frequently about dehydration in contests, he says a dehydrated pilot can be functioning OK, even though he is becoming seriously dehydrated. He can find Uvalde (this was before GPS) He can perform his high speed, low altitude pass through the Finish Line, But when he pulls some G's in his pull-up, the G's can be more than his severely dehydrated mind can handle and .............................................CRUNC H, he crashes in a housing area. I finished up the back of the barn and was washing the South side (much easier, don't need the ladder) and I remembered ANOTHER Finish Line Accident. Cal City, Nimbus 2, (Cindy can give dates & details) This Nimbus 2 driver comes in low, but not very fast, flew through the Finish Line and pulled up very steeply, stalled and was killed, right in front of the Finish Line. It was widely believed that the pilot was dehydrated, was able to find Cal City, performed his low pass through the Finish Line and ................................................

Hey JJ - What about high-speed passes in motor-gliders ?
See ya, Dave "JJ Sinclair" wrote in message ... Isn't there an FAR that says aviators will not fly below 500 feet, if over people, places or things, unless they are in the act of landing? This question was asked by a pilots wife/crew at a nationals. Her motorhome was located on a permanently closed runway about 500 feet from the active runway. The finish line was over the closed runway. I didn't have an answer for her, do you? JJ Sinclair |

Drink your water and don't pull G's 'till you pass
out. That power washer will keep you hydrated! You know I can't resist telling you how unsafe it is to stand on top of that 20' step ladder you mentioned. I think it's even more dangerous than contest finishes. Here are some facts from a Ladder Safety website: 'Every day, one person dies as the result of a ladder fall. Each year, 65,000 people sustain injuries severe enough to require treatment in hospital emergency rooms.' Might have to ban you from power washing your barn - for your own safety, of course. ;-) The defense rests (with a chuckle). 9B At 20:48 04 October 2003, Jj Sinclair wrote: Our barn has that gray grungy look that old wood gets, so I have been power-washing it in preparation for a coat of clear Urethane.

I meant not "necessary for takeoff or landing". The things I mentioned are not necessary for landing. Lots of people do them as a normal part of their landing, but they could land at the far corner of the airport (or off-field) to better follow the FAR's, if JJ's legal opinions were correct, not ridiculous. Lots of other people make low passes as a normal part of their landings, right under the noses of FAA officials, the ones who get a weekday off with pay visiting glider contests. I guess JJ is right that low passes are illegal! The seventh level of hell: eternity with JJ, John Cochrane, and the guy who determined that rigging a glider required a logbook entry as preventative maintenance, until the FAR wording was changed.

One time I fould myself too low to make the A/P. The best landing option was at the local high school on a vacant play field. Had to make final over a soccer field (occupied). An irate parent complained to the FAA. I talked to an investigator & explained the circumstances. Her only comment was "After flying over so much farm land why did you have to land close to people?". I went thru why gliding is different from operating power A/C (more uncertainties, etc.) and that was the end of that. Nobody was hurt and nothing got damaged. Translation: no enforcement action. What if there were a few kids on all the available fields, and you had no other landing options? Would you have made a low pass to clear the field? What if you had never done one before because you viewed low passes as irresponsible? |

Flying head down is never necessary. The center of the finish cylinder is
almost always close to some visible marker on the airport. If it isn't, I ask the CD to move it so it is. My software beeps when I cross the boundary of the cylinder, does yours? Finally, I only glance at the computer once in a while to see if I'm falling below glide slope, which I'd also be doing with a 50 foot gate. But then again, I'm not anal about finishing at precisely 500 feet... I don't agree. When you approach a cylinder, you are aiming at its center. I haven't seen a computer program that optimizes the point on the cycliner you should be aiming at given current position and altitude and interpolates your desired finish height to that point. Instead you are looking down as the distance clicks off, and checking your altitude to make sure that you don't fall slightly short. As noted in earlier threads this means more heads down and more variations in traffic height and speed, all converging on a much smaller area (the optimum point on the cylinder). Finish lines are almost completely heads up. If you can't judge 50 feet looking out the window, you have problems... certainly becuase your altimeter is showing a variation of 50 feet or more since you set it at takeoff. Additionally, traffic speed is much closer to uniform. Low, slow gliders land straight ahead rather than obstructing the finish line. And I've yet to encounter a glider at my height circling 1 mile from a finish line. 91.119 Except when necessary for takeoff or landing, no person may operate an aircraft below the following altitudes... My high speed finish is typically the crosswind or downwind leg of my pattern. I have, on several occasions, thermalled away from a high speed pass (never at a contest). There you have an argument. Otherwise I'm excercising my options as a pilot to conform to a standard pattern... one established by contestants prior to the contest. I am therefore within the requirements of 91.119. Be careful when citing book and passage from the FARs. I know for a fact that you don't follow some rules (none of us do) as scrupulously as you are applying them in this case. I can find some gray in 91.119. You'll be hard pressed to find any in 91.155. Virtue: the behavior we demand of others, but excuse the lack of in ourselves. |
