In this particular instance for example, the student might have reacted badly and so rapidly and forcefully the instructor could not override the student's stick forces in sufficient time. Or the instructor may not have been 'guarding the stick' as closely as the situation/student 'naturally warranted.' Or the PIC may have been flying 'by eye too much' (as distinct from also using the ASI and yaw string as cross checks to the sight picture). You get the idea...we can never know for sure. Are these training flights mendatory under FAA rules? I believe so, but have never pretended to memorize the FARs/CFRs. I expect others will correct me if I'm wrong, but in any case, I *expect* to cover this scenario in some form or other in any flight review, simply because it's an unavoidable - and none too unlikely - scenario when taking aerotows. My approach when taking (the still mandatory, but) what were originally called 'biennial flight reviews' has always been to discuss the premature release scenario prior to getting into the glider.

I don't think so, but s/he should definitely avoid any instructor who doesn't take them life-/glider-threateningly seriously, and who is not also willing beforehand to discuss them in detail, not only as a 'theoretical thing' but in the circumstances pertaining to the airfield in question. Many airfields in the western U.S. *will* result in broken sailplanes, if a premature release from aerotow occurs 'too low.' I remember once during BFR the instructor pulled the release on me in the Blanik at about 200 feet, I had to do 180 turn and land down wind from very low altitude. I think it was dangerous and unnecessary even for an experienced pilot as me. Andre And you were probably correct! Best Regards, Bob W. Condolences to everyone involved.

A few years back I was at a SSA CFIG re-validation seminar in Seattle and there was a discussion of rope break training prior to solo sign- offs. I was a solo student at the time, just there to learn. I mentioned that I had never done a rope break but had been signed off solo and was made to stand and repeat that while the SSA safety team (Carlson and Wander I think it was) listened with horror. The next weekend I went to the field and performed 4 down to 200' and still try to do 3 or 4 every year. Once you do a few and get it down it's a non- event and probably good to have as a skill. On the other hand during my check ride in a 2-22 the DE pulled the release at 200' into a strong headwind and it was pretty exciting getting that bird down when I had been doing them in a DG303 up to then. That same DE is in a local hospital today after crashing while performing a rope break in Montana last week, the other pilot was killed. Those are two very different data points to try and reconcile.

Bart This discussion reminds me of similar discussions surrounding spin training in the power world. So many students and instructors were killed during spin 'training' that the maneuver was eventually banished from the required training curriculum. We in the soaring community should be taking a very hard look at how many pilots are injured killed in actual PTT (Premature Termination of Tow) events vs how many are injured/killed in SRB (Simulated Rope Break) events. I would be willing to bet real money that the statistics do not support the continued use of SRBs in training and/or BFRs. We don't do base- to-final turn stall/spin recovery training for obvious reasons (so the saying goes, "You can only do a base-to-final-turn stall/spin demonstration ONCE"), and SRBs are just slightly less dangerous. BTW, at the risk of starting a religious war, rope breaks, spins, and other dangerous maneuvers can be simulated realistically, at any altitude and weather configuration in Condor. If we feel we must continue to do SRBs as part of a training/review curriculum, they should ONLY be done in Condor. The military, GA, and corporate/ airline communities figured this out a long time ago, and now that we have a realistic soaring simulator, we should be doing it too. If you haven't tried this in Condor, you should. TA |

Rope breaks are definitely exciting. I vividly remember my first one,
six years ago prior to solo. It had me so worked up I had trouble sleeping the night before, but the actual event was no where near as bad as I'd imagined. The worst one I've experienced was when the tow plane had "engine failure" and started slowing down after I was flying but before it left the ground. Realistic, but my heart still beats faster when I think of it. Another high stress situation, as pointed out above, is when you're just below pattern altitude about to turn downwind and you have lots of choices of what to do. But for all the drama, I believe rope break practice is very necessary - in my short soaring career I've seen 3 unintentional rope breaks. All turned out just fine, because the pilots knew what they had to do. -John |

Bullsh**. Andreas Have to agree - if you aren't there, you aren't there. HOWEVER, I do have some difficulty with trying to come up with a bunch of canned answers on how to handle each emergency. In fact, I would suggest that the cure is worse than the disease. Too many variations of problems. I have had personal involvement in, or first hand knowledge of, at least 6 events that could have been very serious. The solution to each emergency was "fly the airplane-save yourself". After that is established, say inside the first 2 seconds, the next common denominator is "get rid of the rope". To heck with signals. In many cases there is no way for the rope to back release. I have personally witnessed a case where this was the difference between life and death. Life won. I have personally been involved in a case where if the rope had not released we would have been in big, big trouble. Signals in NONE of these events would have had any effect on a safe outcome, in fact they would have likely been detrimental due to the short time limit involved. I might emphasize - the same "save yourself first" applies to BOTH ends of the rope. |

TA- Hide quoted text - - Show quoted text - I completely disagree. Condor can be useful for many things but I do not see how it will simulate the real world stress that occurs during an emergency situation. My experience is that most pilots will make at least one important mistake during their first PTTT. Some of these include. 1- Not having a plan in mind that is correct and ready to implement- the "what would I do?" scenario. 2- Many turn the "wrong " direction- most commonly to the right because "that's what we always do". 3- Failure to recognize the situation in the first place- "why are his wings rocking?" 4- Not establishing the correct attitude to maintain control with adequate margins. It's not just nose down. 5- Failure to clear for traffic on return. 6- Not establishing proper glide slope back to safe landing point. 7- Huge tunnel vision due to surprise and related stress. 8- Release when tug rudder is wagged to indicate "something is wrong with your glider". 9- Failure to recognize thr transition point from "I don't have enough energy margin to return to the field" to "Now I can return". Take off/ launch accidents are a significant portion of our losses. We must continue to train and retrain these skills. UH |

Take off/ launch accidents are a significant portion of our losses. We must continue to train and retrain these skills. UH Hank, Well, there is a huge body of evidence from GA, airline, corporate aviation, and military aviation that indicates that ground-based simulation is very a very effective training tool for emergency procedures, and is MUCH safer than airborne training. In a simulator, bad situations and/or bad decisions by the student can be allowed to play out to bad endings, something that can't be done safely in flight and is usually much more effective in getting the point across. You may make the point that since the student knows he can't die in a simulator, the real stresses can't be duplicated. However, I would argue that with airborne training most students think they can't die because there is an instructor right there to save them, so the same argument applies. A student can practice realistic rope breaks in Condor by having an assistant hit the release unexpectedly, just as in real life. The student must perform exactly the same functions (lower the nose, establish a bank in the proper direction, look for an appropriate landing area, etc) as in real life. I can pretty much guarantee you that the first few times the student does this, their reaction will be indistinguishable from their reaction in real life. Moreover, the situation in Condor can be easily configured so the student has no hope of returning to the field, and therefore must accomplish a safe off-airport landing - try that in real life! After 10 or 20 (or 100) SRBs in Condor, a student will be very well-drilled in rope-break procedures for a wide variety of situations, much more so than a corresponding real life only student who typically is exposed to only a few well-planned and very safe SRBs. For less than $300 (assuming you already have a decent PC) you can have a training tool that has been shown over and over again to be effective in saving lives. Need I say more? TA |
