Major snip...
..."Will pilots of ALL skill levels and currency be best served by a simple or complicated procedure?" "Is creating a mindset that turning down adopted offer the best chance of survival of the pilot, even at the expense of glider damage?" I could be wrong, but sometimes I sense a tendency to "reductio ad absurdum" on the part of some folks - to convince others of their point of view? I dunno...but as a non-instructor, glider-only pilot, I managed to mostly-weekend-acquire ~2600 hours without ever contacting the ground "out of control," to also safely and sans alarums demonstrate the proper response(s) to simulated low-altitude, departure-end rope breaks, and I WAS surprised when my ab-initio instructor (initially, verbally) introduced the concept of a not-that-flight-pre-announced low-altitude rope break as a possibility for my imminent future...and then who "immediately asked all the expected 'silly questions'" of my instructor. That noted, nowhere along the line did I ever get it into my head things like: 200' agl is an absolute go/no-go turnaround altitude; or a downwind landing on the departure runway is ALWAYS to be preferred; or that no judgment was required to safely and effectively respond to a low-altitude rope break; or that it was "simple" (or, "complicated" for that matter) to pilot my way through the post PTT attempt. What I DID get into my head - and I can't remember if I did this entirely on my own (out of fearful respect for the fragility of my "somewhat resilient pink body") or through some combination of instruction, reading, cogitation, etc. - was that it mattered VERY MUCH that I do certain things as PIC "correctly" - for under certain (thin margin) circumstances I would not get a second chance. As many of my math instructors loved to say, It was "immediately obvious to the most casual observer" that a low-altitude rope break was a thin margin event, and it was up to me to "handle it right" - or else my frail pink bod would be at higher risk than it needed to be. IMHO, anyone who gets caught up in defending a stance I'd characterize as "do it this way or you're wrong," when "this way" is procedurally based to the discussional exclusion of maintaining solid flight control is missing the point to a certain extent, and - yes - I understand the nature of instruction and the need to instruct using "building blocks of knowledge"...which is the way I've "forever" thought of "the magic 200 feet" concept. It's a great place to start. It isn't fundamentally dangerous (from a control of the glider perspective). It's not fundamentally difficult to pilot as Joe PIC. It's not appropriate under all circumstances...while (in my view) "hitting the ground under control" IS appropriate under all circumstances. The question then becomes, "What ground?" That's where more judgement enters the picture. As others have noted, it's not at all uncommon in the intermountain western U.S. to aerotow launch from fields where accepting something other than a downwind landing on the departure runway from 200' agl in the event of a low-altitude rope break is (obviously, unarguably, inevitably, etc...) "the best/safest thing to do." Being 100% first-person-ignorant of the circumstances surrounding the tragic crash sparking this (contains much food for thought) thread, several of my operating conclusions a 1) we can never know for sure what was in the deceased pilot's mind; 2) he likely hit the ground "in a non-flying condition"; 3) 2) is further evidence for me to "not do that." Tying the preceding into "the magic 200' agl PTT altitude" is easy enough for me in that if "in my judgment" I think 200' IS sufficient under the circumstances to attempt a turn-around, then I'll do it; if not, then I'll do something different...but whatever I do I'll work darned hard to ensure I maintain control all the way to the ground. Duh??? Respectfully, Bob W. |

Duh??? Respectfully, Bob W. I cannot argue against the above. From what I have read in this thread I have gained the impression that in the event of a launch failure at 200 ft or above the recommended procedure is to turn back to the runway. This is completely different from what I have taught for 45 years. In the event of any launch failure the question that should be asked is "Can I land ahead" If the answer is "yes" then land ahead, height does not come into it at all. If, and only if the answer is "No" or "Not sure" should another action be considered and executed. In any event I would never simulate a launch failure at 200 ft if there was not room to land ahead. I would and do simulate launch failures at 300ft and above if there is no room to land ahead and allow students to practice this, turning back as necessary. The reason is simple, while a pilot may be faced with having to turn back at 200 ft the risks in doing so are not justified in training, in the same way that we do not practice very low winch launch failures, just after liftoff, or practice groundloops to avoid obstacles both of which are covered by briefings. We do set up the ultra low level launch failure situation from a normal approach but we never simulate it off the launch because of the dangers involved. There will always be circumstances where the "normal" procedure is not possible but we do stress that the important part of the outcome is that the pilot has the best chance of survival, an undamged glider is not a priority in these circumstances. |

If, and only if the answer is "No" or "Not sure" should another action be considered and executed. From my U.S.-centric, non-instructing perspective, perhaps this is one of those nuanced differences between FAA-driven-instruction and BGA-driven instruction? What I think I remember of my instruction - and what I think I've seen ever since then from observing others' instruction - was that "considering all alternatives" before executing a reversing turn from nominally 200' agl in a glider "is no big deal" and ought to be in the glider pilot's bag of tricks. I've never thought the conceptual approach in any way fundamentally marginal in a life-threatening (mine!) sense. That's not to say the sensibility of the BGA approach wasn't - hadn't already - been hammered home...as in I'd already internalized that Joe Glider-pilot's Rule Number One is to never be beyond safe gliding distance to a safe landing field. In my experience, the ONLY exception to Rule No. 1 has been those (mostly western U.S.) fields where there may be a short time window when the "reach a safe field" option simply doesn't exist for whatever reason(s). That's when "fly the plane into/through the arrival" becomes more than a mental concept. In any event I would never simulate a launch failure at 200 ft if there was not room to land ahead. This certainly has been my training/recurrency experience(s)..."merely goes-without-saying common-sense" IMO. I might be wrong in this surmise - chime in instructors - but I doubt even our FAA has felt it necessary to provide instructional guidelines "to this degree of obviousness." I would and do simulate launch failures at 300ft and above if there is no room to land ahead and allow students to practice this, turning back as necessary. The reason is simple, while a pilot may be faced with having to turn back at 200 ft the risks in doing so are not justified in training, in the same way that we do not practice very low winch launch failures, just after liftoff, or practice groundloops to avoid obstacles both of which are covered by briefings. We do set up the ultra low level launch failure situation from a normal approach but we never simulate it off the launch because of the dangers involved. FWIW, my takeaway from decades of avid personal interest and absorbing every flight crunch writeup available to me, is that the risk in these sorts of situations is essentially U.S.-invisible when considering training incidents/accidents. The crunches sticking in my mind have been those involving single-pilots for the most part. I suppose an argument can be made about the longer-term efficacy and mental retention of training, if my memories are valid, but not so much from a training perspective. In any event, I don't think MY personal risk was increased from this aspect of my training. There will always be circumstances where the "normal" procedure is not possible but we do stress that the important part of the outcome is that the pilot has the best chance of survival, an undamaged glider is not a priority in these circumstances. I 100% agree!!! Respectfully, Bob W. |

What you were taught relates to winch launch only. Different rules apply to aero tow. With aero tow at 200' AGL on departure it is almost never possible to land ahead on the runway. Either turn or land in whatever terrain is available off the end of the runway. In many aero tow only airfields, that terrain is not suitable for a safe landing. |

Then ask the question, "Can I land ahead" If and ONLY if the answer is NO or NOT SURE should any other action be considered. |

While I agree that landing straight ahead is best if there is room, your
sequence of events is wrong. On an aerotow the question whether to land ahead or turn should be made on every launch! "Then ask the question" will lead to overload and grief! On tow, once you have decided you cannot land ahead then it may be a turn to an off-field landing if possible, followed by a 180 turn back to runway when safe. (That will invariably be at least 200') I repeat: after a failure is not the time to be thinking about where to go! Tom No, what I was taught and what I teach applies to ALL launch failures, winch, auto tow, and aerotow as detailed above.

May I offer a practical tip? Talk to yourself all the way up the launch to
a safe height (perhaps 500ft), deciding where you will go at every moment should the rope / tug break. Should it then happen you already have the decision made and only have to execute it well. If you, or your trainee, start to do this every launch you will be amazed at what poor decisions you would make to begin with. These get better with the doing of it.

Since it was about a hundred posts ago I offered the same concept, may I say, "Thank you." I am heartened to know that there are others out there who prefer to be prepared and updating their situational awareness during launch, rather than becoming off-launch and then begin 'assessing' the choices. If the assessment is ongoing, the execution of the 'best choice' becomes pretty relaxed. And if we fly to the landing, it is so much more likely to be survivable than falling to an impact. Thanks, Jim. Cindy B |

Then ask the question, "Can I land ahead" If and ONLY if the answer is NO or NOT SURE should any other action be considered. That's how I was taught - first immediate action - fly the glider. Then assess. I was sent solo in a T21 at Portmoak, flying off winch from the SW end, accompanied by a sandbag in the RH seat. Two 360 degree turns and a good landing. Woohoo. Ok - now for the second solo flight - cable break at 300 feet. All I remember of my thought processes at the time was to get the nose down out of full climb immediately before speed bled off, get rid of cable and then assess - unsure about straight ahead (20/20 hindsight - full spoiler and land would have worked), too low for short circuit (maybe), so I made a 90 degree left turn to get some room, turned back to right and landed across the main onto the alternative area across from the hangars, passing in front of the winch. I explained my thought process to the instructor and we reviewed what I had done - got a slow nod and a well done lad. Good enough for me and a credit to my instructors. Was sent back up once we had towed the T21 back to the launch point. |
