In my club 100 hrs total time and a completed 300 km task were the requirement to fly the ASW-20L. Perfectly adequate. People were flying Astir, ASW-15 and DG-300 before the ASW-20. Andreas |

After a 300 km task (the gliders were mostly pegases for that) you could take an LS3 or similar flapped gliders, or a janus. -- Michel TALON |

Agreed. The 20s POH says that the first recovery action is to push the flap fully negative and that the glider will often auto-recover with no further action by the pilot. Height loss and speed gain are impressive: I entered an incipient spin at 45 kts, stopped rotation in a 1/4 turn and then pulled out, returning to level flight 300 ft lower and with 80 kts on the clock. You're quite busy on take-off too: the POH says to start the run with one notch of negative flap for better aileron control. The ailerons start to bite about 30 kts and you need to move to neutral flap at that point because it won't lift off in negative flap, but you NEED to be in neutral before you hit 40 or it will pop up when you move the flap lever. If you miss neutral and hit thermal the first few launches, leave it there or you'll likely to find yourself way below the tow plane. The other thing that nobody has mentioned yet applies to both gliders. Learning to fly a flapped glider is similar to learning to drive in an automatic car and then transitioning to a manual shift. By that I mean that operating the flaps is easy, but being in the right flap setting at all times and getting it engrained that the flap lever is your primary speed control takes time: it took me 30-35 hours to get to the point where flap use became something I didn't need to think about before doing it. I had nearly 300 hours by the time I flew a '20, with at least half of than on the club's Pegase and Discus. -- martin@ | Martin Gregorie gregorie. | Essex, UK org | |

It took considerably longer to lift off than usual, and was *weird* on tow until I finally pulled my head out and realized I was in the wrong flap setting, but it does work. -- Mike Ash Radio Free Earth Broadcasting from our climate-controlled studios deep inside the Moon |

How one mentally approaches flaps and their use (or, non-use, as the transitioning-case may be) is, I believe, vastly more important than seeking comfort in hard-n-fast 'stick-time rules.' For example, if the flaps are camber-changing-only (e.g. LS-6), you can simply set/leave them at zero until such time as you feel comfortable experimenting with them. Both ships permit use of spoilers to assist initial aileron response if aero-towing (just as a transitionee might already be doing in unflapped glass). Further, Schleicher's '20 (and Rolladen-Schneider's LS-6) allow (insist-on) the use of spoilers as the primary glideslope control device. (Kinda-sorta related, just because the ship being transitioning to has retractable gear is no reason to believe one *must* retract or cycle the gear on early flights.) No harm in using the KISS philosophy of transitioning... If you die on your first flight in such a ship using such a technique, perhaps small comfort can be (briefly) obtained from the knowledge flap (mis-)use wasn't the proximate cause of death. :-) I have flown neither,but I think if you spin either your first action is to select negative flap. Again, this advice may be OK (as far as it goes), perhaps even in the Pilot's Operating Handbook (I don't know)...but not without some caveats. The devil - as always - is in the details... The first *2* flapped ships I transitioned to *had* no negative flaps (or, any spoilers, either). And while in neither one did I ever experience an inadvertent 'departure from controlled flight', in both the best (IMHO) potential-overspeed-avoidance device in their bag of tricks had such a thing happened and startled/scared me into not 'simply'/immediately reducing the AoA (which worked every time I used it) would have been to *'2nd-immediately'* roll/pump on ALL the flaps. Sure this would have had the short-term effect of increasing the wing's effective AoA..but so what, as neither ship could 'reasonably' be induced to exceed max-flap/maneuvering speeds with 'em full down. It would've bought time to sort things out without eating vast vertical gobs of airspace or zooming above maneuvering speed. So - is it preferable to 'inadvertently spin down through a thermal gaggle' in an AS-W 20 and recover at high-ish speeds with negative flap, or, to spiral down 'perhaps somewhat stalled' but vertically somewhat slower with full flaps? (This is not a trick question.) My vote is to avoid the situation in the first place. This'll work in the LS-6, too. :-) Regards, Bob W. P.S. Apologies for treading so far out onto this particular discussional ice, but I must've 'felt a need'...! |

Apologies for treading so far out onto this particular discussional ice, but I must've 'felt a need'...! Well said it is always best to avoid the situation in the first place, but there is also no substitute for knowing proper recovery technique when it does happen. To answer Johns question about my experience, let me first say that I have just under 100 hours in the 2-33. That being said I have no intention to go out ,buy a high performance glass ship, and go soaring with the thought that I will just get the hang of it in a few hours of flight. My intentions are to purchase the glider now during the winter months to "hopefully" fly after at least 6 more months of active gliding starting in the spring. I was planning to get a few more hours in the 2-33 first, especially after 6 months of no flying(it snows up here in northern Indiana),I would want to be refreshed in the trainer .. After that I plan to transition to the Clubs 1-36 glider for a while and then get some additional hours in a 2 place glass ship. Not sure when I will actually be ,ready to fly the new one, I don't know how I could put a minimum hours requirement on it. I was leaving it up to my confidence level and abilities to determine when the time would be right. We have some excellent instructors at our glider port who will always keep a watchful eye out. I am very competitive and welcome the increased complexity and challenge of a flapped ship. I am looking forward to cross county flights and eventually competition. Am I sound in my thinking, or am I out in left field? |

Modern glass ships aren't "hard" to fly, but they presume a sharp pilot with some finesse that generally isn't learned in a barge like a 2-33. You don't need answers on r.a.s. (witness willing advice from people who HAVEN'T FLOWN THESE SHIPS (that's a pet peeve)), you need a coach. The ideal coach is a CFIG who can fly with you and has experience in the general direction you are headed (XC, glass, competition, record setting, whatever). There's been some good advice given in this thread, also some complete crap. I remember well being in your shoes and have nothing but encouragement to offer. Good luck! -Evan Ludeman / T8 (ASW-20B) |

Am I sound in my thinking, or am I out in left field? I agree with Evan, but would also add that you should get some time in a two seat glass ship before tackling a glass single seater. You'll learn a lot about speed control from flying any of them. Good speed control is a necessity because a flapped glider is much more slippery than you'll be expecting. The ASK-21 is a pussycat and very well behaved. Time in one would be good preparation for the likes of baby Grobs, Juniors and Libelles. Before tackling anything more slippery (Pegase, Discus, LS-6 or ASW-20), a bit of time in a Grob G.103 would be useful. The G.103, unlike the ASK-21, has a tendency to drop its nose and accelerate in turns. BTW, I've flown all the types I've mentioned here and also have one flight in a 2-33, so have some idea of how it handles and its dragginess. -- martin@ | Martin Gregorie gregorie. | Essex, UK org | |

Am I sound in my thinking, or am I out in left field?- Hide quoted text - - Show quoted text - - In my opinion, you should first do the fiberglass transition before you even look at a fiberglass single seater... Then, go rent a fiberglass singleseater and fly some more. Take a week (or more) of vacations and travel to Arizona, California or Nevada (predicatable good weather). Then look at flaps. Spitzers were good army training gliders 50+ years ago and overwhelming majority of civilized world since then successfully transitioned to sailplanes. My guess is that you weren’t drawn to the sport because of ancient Greece. There are numerous FBOs clubs offering fibrerglass training/transition. Just because you might survive first couple of hours flying a fiberglass, flapped sailplane doesn’t mean you wont have gaps in your training. Try avoiding situations where you were wishing to be on the ground when flying a sailplane... This should be fun, there is no reason to expose yourself to unnecessary and easily avoidable risk. |

I watched a friend pull the wings off a 301 Libelle when the airspeed got away from her shortly after putting it in negative flap on her first flight. My first flight in a flapped ship was three years later in an LS-3. I was 18 and had 79 total hours. It was a dream to fly with no bad habits. Four years after that I got into a Ventus A with a grand total of 155 hours under my belt. It was much more of a handful, especially with the 16.6 meter tips. I suppose it's mostly about knowing when you're ready and taking proper care - regardless of what you hear on r.a.s. If you're not sure, get some dual time with an instructor who has high performance glass experience. 9B |
