Kawa rough landing?
"The only solution is prevention..." this is the same philosophy the faa has used in eliminating spin demonstration from private licensing and imop has led to a marked degredation in pilot awareness and skill., The very fact that a pilot becomes disoriented in the early stages of a spin or becomes uncomfortable when pitched into a steep bank is the very reason one needs to experience it again and again at altitude. The very act of physically experiencing the sensations both real and percieved during spin approach and entry become THE essential tool in survival.
As for outlandings, multiple experiences create a memory resevoir of knowledge in making very fast decisions and corrections which turn what could be a glider damaging landing into one that just raised the pucker factor a little bit. Its the very fact that we rarely experience spin and rarely experience outlandings and can't handle them when they are thrust on us that is a large factor in the many fatal accidents we see today. |

Kawa rough landing?
As a corrolary to my post above let me toot my own horn and poss a few questions to you.
I have spun my ship more than 30 times, and probable done 1,000 incipent spin entries. I have practiced flying my bird on the very ragged edge of stall in every imaginable condition, weak weather, booming 10k gusty thermal condx, gusty wind condx etc. I have made a point to know every nuance of my bird so when thrust into an abnormal condition, my reactions can be automatic without needing the precious seconds to try and figure out what just happened. Can you say that about your bird? If so that great and that is what every xc glider guider needs to work toward. In off field landings I can come over a 50 ft obstacle and have her stopped within 300ft in no wind condx, much less with a head wind. I have landed in fields, parking lots and baseball diamonds and have'nt given those landing a second thought. They were no big deal due to having spent literally thiusands of dollars on pattern tows practicing every concievable approach I could dream up of encountering. When is the last time anyone on this group has paid for about 10 pattern tows and practiced the skills needed when the time arrives? I do that every spring just to get tuned up. I'm not talking about pretty box patterns and long smooth touchdowns, but I practice very steep full spoiler/full slip approaches with the very minimum of energy in order to get into a postage stamp. Can you? If so thats great, but I dare say very few on here come anywhere near to trully knowing their ships and what they are and are not capable of. |

Can you? If so thats great, but I dare say very few on here come anywhere near to truly knowing their ships and what they are and are not capable of. Any time someone lands their motor glider with engine extended has to ask questions about what happen. No one would ever deliberately choose to land with a extended engine and expect the best outcome. It is like flying with full spoilers with no ability to change things, you are in uncharted territory. The right thing would have been to start the relight at a higher altitude, then it it does not work, retract the engine and fly a more controllable aircraft into the best options available. The fact the engine was still out tells a story about pilot errors and understanding. BG |

If you push into an area with poor landing options you should not be surprised when things turn out badly. Tom Hmmm... I certainly have no quibble with your 2nd paragraph. But at the risk of descending toward tautology, careful reading of the clip I seconded doesn't suggest (to me, anyway) the poster was suggesting anyone practice spin entries/recovery from low altitude; I inferred the poster's intention was *full* spin practice occur at a safe altitude, so that Joe Glider Pilot's "mental reflexes" (and by implication, physical responses) move away from "Holy crap...!" and toward, "Just another 'typical' spin entry and normal rotation...and I can do what I know needs to be done whenever I darn well please, and, in a timely manner!" ('Typical' is in quotes because I'm of the opinion that spins are sufficiently complex aerodynamic phenomena that to complacently assume they will 'always be normal' is a level of complacency beyond me...and, I've practiced what I preach.) Practice - physical, where safely possible, and definitely mental (e.g. how best to handle safely touching down on an upsloping off-field landing) - is a good thing, IMO, for every practitioner of the soaring arts. As always, YMMV. Bob W. P.S. Just for the record, one of the things for which I consider practice entirely unhelpful and unnecessary is bleeding. Another is pattern-height departures. And below VMC engine-outs in a light twin taking off from a short field. Ideally, every pilot has such a list. :-) --- This email has been checked for viruses by AVG. https://www.avg.com |

For example, my ASH26E lands easily with the mast extended, and it's definitely NOT like flying with full spoilers. I've tried it a couple times, and it was such a non-event, I decided it was pointless to practice anymore. Generally, a pilot will land with the mast extended because it will not retract, or because he is too busy landing to retract it. Of course, it will not glide as far with the mast extended, so I don't begin a restart until I am within a mast-up gliding distance of a good landing place - just in case it doesn't retract after a failed start.

" Just to highlight the salient point Not really the point I tried to make, which is many motorgliders do not "plummet" or become less controllable because the mast is up, so you don't have to fear a landing in that configuration. If you are flying a normal pattern, you just use less spoiler, or turn base a bit earlier. The situation where the reduced mast-up glide distance is an issue is a high restart many miles from your chosen landing place. It's just one more factor in your arrival height calculation, along with wind, wing loading, and bugs. -- Eric Greenwell - Washington State, USA (change ".netto" to ".us" to email me) - "A Guide to Self-Launching Sailplane Operation" https://sites.google.com/site/motorg...ad-the-guide-1 - "Transponders in Sailplanes - Dec 2014a" also ADS-B, PCAS, Flarm http://soaringsafety.org/prevention/...anes-2014A.pdf |
