Duh! However, I think your implied point is that if a pilot tries a turn, the aircraft will be out of control. Obviously, I disagree. If a pilot can't retain control while making a simple 180 degree turn, the situation was dire long before the emergency arose. Now, lets define the "ground" you're going to crash into. Lets say there's a rock quarry off the departure end. Solid surfaces are vertical and all horizontal surfaces are water with no climb out options. The occupants will die in the crash or drown a few minutes later whether the aircraft crashed under control or not. My point is there are situations where no "straight ahead" option is available. My situation isn't quite that bad - it's only water filled gravel pits. The only field proven landable is VERY small and requires a 90 degree turn at treetop level around a large tree. Turning back, when possible, is always the best option. It pays to be good at it. The good news is gliders can turn back with generous safety margins. The wild card is the pilot. |

The good news is gliders can turn back with generous safety margins. The wild card is the pilot. Let's just emphasise this again. If the rope breaks at normal aerotow speed, you should be able to complete a 180º turn and be at normal safe final approach speed with as much or more height as the moment the rope broke. The glider can. Easily. |

Ignore the KISS mantra at your peril. |

Bill, just answer the 3 questions honestly: "Will pilots of ALL skill levels and currency be best served by a simple or complicated procedure?" All skill levels? Pilots either meet the minimum skill level or they don't - and the minimum requires them to be able to return to the runway. If they can't demonstrate that level of skill, they don't fly. In many, if not most cases, a return to the departure runway is the simplest solution. An off field landing dealing with trees, fences and unimproved ground is more often the complicated - and less safe - solution. "Is creating a mindset that turning downwind is the best option suitable for all conditions?" No one suggests creating a "mindset" except to use good judgement in selecting the best option. No one is saying turn "downwind" - they are saying turn back for a downwind landing which is a different thing. No one in this absurd thread said "all conditions". "Does the procedure adopted offer the best chance of survival of the pilot, even at the expense of glider damage?" Yes, in many if not most situations, landing on the departure runway does offer the best chance of survival. |

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. |

I agree with Bill. If you are scared witless by an instructor pulling the release at 200ft you have no business flying a sailplane solo.
