Hello Reno approach experimental glider Nxxxx I need to climb into class Bravo to avoid exceeding Vne. Experimental glider standby - American 1364 descend and maintain 14,000. American 1364 out of 210 for 14,000 Experimental glider Nxxxx this is Reno approach say position and altitude and say again request.

In this scenario the advice to declare an emergency on the appropriate frequency and state your intentions/present actions will at least keep you legal with regard to that portion of the flight.

You can't have your cake and eat it too, with regard to the regs and proper procedures, but the best course of action involves doing the right pilot-thing NOW, declaring an emergency as soon as possible, and filing an ASRS report promptly after the flight. I've filed lots of them. And, I've never waited for anything to come off the airplane prior to taking the action needed, and then announcing the situation to ATC when reasonable to do so. You are not asking for permission--you are telling them how it is where you are and what you are doing about it, in order to keep them in the loop. They will do what they can with other aircraft in the vicinity that don't happen to be falling out of the sky at that particular moment in order to minimize any conflicts. _File an ASRS promptly_ after any unusual incident. It helps the system, and it helps YOU. Jack |

It helps the system, and it helps YOU. Diverging a bit: I assume the OP is subject to regulatory action against any license he has (presumably glider at least). However, the glider he was flying is an ultralight and can be flown without a pilot's license and without the glider being certficated. Can he keep flying it (assuming it hasn't been given an N number of course)? Shawn |

That would have alerted them to check for any possible conflicts and clear the area around you of other traffic until you could get clear of Class A airspace. You were negligent - and in violation of FARs - by not doing this. Reno could have easily cleared you into Class A until you could take appropriate actions. We ARE allowed to violate FARs in an emergency, but this does not relieve you of your responsibility to minimize the violation to the extent possible. Fortunately, you were carrying a transponder... Doesn't this run contrary to the standard mantra of Aviate, Navigate, Communicate? When something bad happens, first thing you do is fly the plane. When you're exceeding your Vne by a large factor the first step should be to quickly reduce speed. Talking to the controlling authority of the airspace you're violating while doing so is a good idea but it should come dead last on the priority list. From the way the story was told, it sounded like by the time the pilot could catch his breath and stop worrying about his imminent demise long enough to devote some attention to the radio, he was already back below the class A. -- Michael Ash Rogue Amoeba Software The short answer is No. Here is what he said: "I gently pulled the stick back and translated speed into altitude going above 19k. At about 70 knots I pulled the spoilers and got myself down to below 18k." Sounds to me like he had plenty of time to do that communicate thing. Hell, I can thermal, check airspeed and watch out for other gliders in a gaggle while simultaneously talking on the radio. I once was dealing with a microburst in the mountains when the controller at Hailey wanted to know my situation (or something to that effect). I told him I was busy and would talk to him later, which I did. Tom |

Dave, You had another option open to you other than pulling up to slow down to extend brakes and therefore bumping higher into "no-no" airspace. You could have maintained your airspeed but turned left or right to get into weaker lift or light sink. Once you had lost enough altitude then eased back over into the stronger lift regions. Larry "01" USA Ventus 2bx " wrote in message : Hi Gang Last week Minden had some excellent wave soaring. Off tow at 7.7k msl and within minutes up to 18k. I decided to go up north skirting Reno Intl. I had the transponder on and was monitoring Reno Approach. My goal was to try and fly as fast as possible maintaining an altitude very close to 18k by speeding up in lift and slowing down in light lift or sink. This worked well for the first 35 miles where my IAS (indicated air speed) ranged between 50 knots and 110 knots flying never less than 17k. Then I got into some real lift and pointed the nose down and noticed my Becker transponder registering 18.2k which is, of course, a no no. I then glanced at the IAS. It read 138 knots which is 165 knots TAS. (Every 1000 feet of altitude above sea level results in an error of 1.5% in IAS.) So what to do? If I pulled the spoilers at that speed, the shock might destroy them or the glider. So I gently pulled the stick back and translated speed into altitude going above 19k. At about 70 knots I pulled the spoilers and got myself down to below 18k. I wonder if ATC caught that? Why was this so bad? Well the VNE at sea level for the SparrowHawk is 123 knots and it has been demonstrated that at 171 knots the wings come off. This really gave me cause for concern. How quickly one can get into trouble by not paying attention. In the future I will fly slower and use the spoilers to compensate for excessive lift so as to maintain altitude. This story raises some questions about VNE at various altitudes which should be of interest to all of us glider pilots. I Googled combinations of words such as "flutter altitude", "VNE altitude" and "aircraft breakup altitude" to try and come up with information on whether the flutter/breakup characteristics of an aircraft are less at altitude than sea level at the same TAS. Intuitively it would seem so but intuition may not work here. I found nothing useful. I know that the World's ultimate high altitude motor glider the U2, which was designed in the 50s, had much study done on it with regard to its operating speed window of about 20mph (stall to breakup)at 80k feet msl. There should now be declassified documents on those studies which might answer my questions. I would appreciate any pointers anyone. If I find anything useful I will summarize it on RAS. Flying is often unforgiving of errors and I will definitely be more vigilant after this wake up call. Dave If I recall from training days, you can lose altitude faster in a descending turn than you can in a straight line, even at the same speed. I don't think I can explain this late at night why I think this works, but it sort of makes sense. |

descending turn than you can in a straight line, even at the same speed. I don't think I can explain this late at night why I think this works, but it sort of makes sense.- Hide quoted text - It's due to the increased G's in a turn. Steeper turn, more G's, more drag due to lift required to offset the Gs. Same reason sink rate increases as you thermal steeper. A bunch of G also helps keep the speed down in a steep, descending turn (not a spiral, of course). Perhaps time to hit the books again? Kirk 66 |

I would add a few points to amplify this basically sound logic: 1) Fly the airplane 2) Fly the airplane 3) Fly the airplane If you need to go into controlled airspace without permission to prevent destruction of your airplane and yourself, do not hesitate. Do what you need to do to get back to a safe flying condition. If you get back down bellow 18k promptly it might make sense to call ATC, but I'm not sure what real purpose it serves other than meeting some FAR on reporting youself appropriately and that need might be better served through some other means than a radio call. Secondly, I'm not sure why you'd hang out above 18k long enough to make the call before decending via spoilers, but I guess it could happen. I think I'd be too busy flying the airplane. The airmanship point bears repeating in this case and in general. Whenever you are flying near a limit (controlled airspace, Vne, severe weather, terrain!) you need to exercise extra caution and presume that conditions outside your control (lift, sink, gusts) could conspire against you in the least favorable possible ways. I have seen many people fly under these circumstances assuming that those conditions will remain within (or close to) the ranges they have personally experienced - I think it is prudent to assume something much less favorable and keep margins appropriate to those assumptions. This applies as much to assumptions about expected sink on final glide and it does to assumptions about lift near 18,000'. One needs to be very cautious about watching climb rate when above 17,000', particularly if carrying any significant energy in the form of airspeed. 9B |

If you don't think you are willing or able to follow FARs you should STAY ON THE GROUND! Remember, this is a priviledge that can be revoked. Tom Seim |

Tom Seim- Hide quoted text - - Show quoted text - Oh Tom - you are such a grumpy fellow. I've got nothing against navigating and communicating - I do it all the time. I think most of the people on this thread feel the same way. I just think they are irrelevant if you don't fly the airplane first which it the number one risk factor in Dave's scenario. It's not like 18,000 is broken to overcast with aluminum even around Reno. Secondly, if you do the math, a pullup from Vne to spoiler speed and back down takes aboiut a minute, unless you fart around before you pop the boards. If I'm at Vne and rising at altitude with an uncertain flutter margin the last thing I want to do is get my chart out, find the ATC freq, call them up, go back and forth as they sort out who I am and, if I have a trasponder, give me and ident code so they can find me and give me traffic advisories. I'm in all likelihood back below 18,000' before they even can figure it all out and do anything to help me. Simple. Now, if you are already talking to them for some other reason or have a transponder, then they already know where you are and have already routed trafffic to avoid you. Believe it or not, the controllers don't make a sport out of seeing how close the can fly traffic together, so they'll give gliders a pretty good clearance form traffic.BUT, if you are already talking to them it makes sense to let them know if you are doing something unexpected. I'd just fly the airplane first because the risk of breaking the airplane in my judgement far exceeds the risk of a midair. I am prepared for your next personal attack. 9B |
