Rolfe:
Moved to England from North Carolina before last season. Three thoughts on my experience changing over from aerotow to winch. First, where I've flown (Long Mynd) the winch was only good for 1100 feet in a two-seater (ASK21) flown by a winch novice like me. The old hands didn't get more than a couple hundred feet above that. It was very hard climbing out with so little time/altitude. I was spoiled by 2,000 ft plus aerotows. It was discouraging. Second, I almost got myself into a real fix by not thinking of the airspace above and around the winch run as different from the airspace around and above an aerotow setup. Rules about the pattern--where and how it can be joined need to be developed and reinforced to reflect the difference of a cable sweeping through the airspace above the runway in a matter of seconds with little or no warning to those flying in the vicinity. Third, I used to see a wing drop every other day at the beginning of launches at aerotow operations with no ill effects. As I understand it, dropping a wing at the beginning of a winch launch can be very dangerous, so I was told to stay vigilant and keep a hand on the cable release should a wing drop. Kevin On 4 Jan, 23:42, Rolf wrote: Caesar Creek Soaring Club is investigating the possibility of winch launching on our field. As expected there are very polarized opinions on the merits, value, and safety of winch launching. I would appreciate any rational inputs on the merits of winching or reference data from other sites on training merits and safety. Actual experience data would also be appreciated. Thanks Rolf Hegele President, CCSC |

CCSC President Rolf Hegele is to be commended for soliciting info from
experts and users before bringing an additional winch for winch-to- pattern training and glider/winch currency to CCSC. Aerotows will remain the standard tow-to-thermal operation from this smaller airfield. I wish to thank many of you experts who have, in the past year, already responded with Andrew Dignan, the outgoing club President and current VP, and me. From FARs, FAA & SSA Texts, glider/ aircraft operating handbooks, some internet winch detective work, and your testimony, a small, dedicated group has 1. put together and tested a safe winch operation at two locations, 2. improved the reliability of an older single-drum Gehrlein winch, 3. created operations procedures and constraints, 4. implimented academics and a winch endorsement and currency training program/syllibus. In less than half a year of part-time weekday winching we've winched over 300 times and graduated a dozen'ish current/endorsed winch pilots. Two northern glider clubs are benefitting from a growing group of "switched-on", current and capable CFIGs and pilots. - Jim Goebel What follows is from the Dec 2008 CCSC Newsletter entitled "Winch Flights in Our 2-33’s" by Tom McDonald Our long planned CCSC winch demo was conducted successfully on Saturday, November 1. The group flew seven flights, of which I was personally flying or instructing on six. Tom Rudolf was signed off as a winch instructor during the demonstration period. The intent of the demo was to allow the CCSC and SSD boards to evaluate the program for use at CCSC, and most of the board saw at least some of the flights. Previously, the board approved the use of the club’s 2-33 aircraft in winch operations at Waynesville. We’ve got 28 flights so far in club equipment, including the 7 at the demo. You can watch some of our flights at www.youtube.com/tjm3. Or, just go to youtube and search “ccsc winch.” Winch stats Three hundred and four launches to date have used a little less than two cups of fuel per flight. By comparison, John Antrim’s recent fuel use study for the Pawnees estimated that a 1000 foot release uses about 1.3 gallons. The cost is $15 per flight in our ship, $27 in Stewarts. Even with the higher cost per flight, transportation between the two airports will still sometimes make renting Cubby’s 2-33 more practical than using our own. What you get A lot of fun A winch endorsement (or re-currency) in your logbook Rapid improvement in flying skills Potential significant cost savings Student and currency flying The price issue is important, but not the main thing. Consider value, or bang for the buck. Winch-to-pattern will never replace aerotow in our operation. But if you are a student, winch training is definitely for you. A lot of training flights are spent developing skills in the traffic pattern and landing. A winch operation using two gliders can launch eight to ten flights in an hour. You will get better at everything in a big hurry through repetition, and cut way down on those expensive aerotows. Currency flying uses much the same equation. One instructor told me that the winch operation is not cost-effective, because the short flights result in a very high cost per hour. I disagree. I get a lot out of these short flights, the point of which is precision. I don’t need to bounce along behind the Pawnee to do this. Also, I’ve had four winch-to-thermal flights so far, even with our fairly low release height. I can afford all the aerotows I need to stay current and enjoy myself, but then I’m already licensed. If I were learning, taking multiple flights learning to fly the pattern and land, the cost today could well be prohibitive. I doubt that I could have underwritten my son’s flight instruction a few years ago at current prices. Even if cost were no object, though, the equation of being a much better pilot at a much lower cost per flight is hard to beat. Safety issues Winch launches have potential for problems. I’m not claiming to be an expert – I’ve got my checkout, plus about 20 flights as an instructor. I can tell you with authority that you have to know what you are doing – as Jim puts it, be “switched on.” I don’t see the risk as unreasonable, especially when compared to the 200 foot aerotow rope breaks that we routinely do in training at CCSC. Jim and Gerry are running a very professional operation. I’ve reviewed the winch safety recommendations published in the SSA magazine a few months ago, and we are in compliance. The list of e- mail consultants to this operation now includes Frank Whitely, considered the U.S. winch authority, and the well known Derek Piggott. The engine has a lot of power, unlike some earlier winches. It uses a light rope with a weak link, not a steel cable. The nose-hooked 2-33 glider has benign stall characteristics – important for our short field operation. In fact, full aft stick on the winch will not result in a stall. Rope breaks are a possibility, but not unmanageable. I’ve had the worst case of max pitch, min altitude simulated winch engine failure as a surprise training event, and found it easy to cope. Getting started Jim Goebel and Gordon Penner developed a PowerPoint presentation covering the academics, now available online. Taking a demo flight first might make this ground program more meaningful, since you would have a better frame of reference. Jim Goebel has an e-mail list of interested pilots. He sends periodic notices of available dates, and the rest of us let him know if we can be there. Email Jim at or me at to get on the list. The future Unfortunately, the recent demo was contentious. Six of the board members approved the demo on the November 1 date via email, with another member stating only that he would not make the meeting. There was also approval in advance to set up and begin winch ops prior to having a quorum of the board present. On October 31, one member vigorously objected to conducting the operation without another board vote. Unfortunately, this resulted in our representatives on the board spending their meeting discussing the propriety of conducting this long-planned and pre-approved operation on that day, rather than considering the merits of the operation itself. Also, none of the board members not already involved with winching even came out to the flight line, much less took a demo flight. So, the demo may not have served its stated purpose. There are also issues with having what amounts to a commercial operation within the club that will have to be addressed for the long term. I am hopeful the incoming board will take a fresh look next year. |

There are also issues with having what amounts to a commercial operation within the club that will have to be addressed for the long term. I am hopeful the incoming board will take a fresh look next year. Authority, hardly. I do try to help and invite others to jump into the pool, many heads are better than one. Effective winching is teamwork and training. Communications is key to safety. CCSC already operates with a team concept. It would seem trivial to extend this to winching. What you don't want to do is have everyone learning to drive the winch, but develop a cadre of competent drivers for the winch and retrieve. We quibble quite a bit in the winch design yahoo group over details, yet it's a gas for gear heads and engineers alike. The process is simple, yet the concepts are complex when it comes to power, tension, materials, design, and coupling it all together. Dealing with nature's variables just takes time and experience. Wind, hill curl, shears, cross winds, convergence zones, thermals and sink are all transitory events that guarantee it will take any driver lots of launches to experience and understand what was different about that last launch. Sometimes you have to compare notes with the glider pilot to figure what happened. Top end winches will remove some of this. Boring? Only when the instructor and student are doing ground school at the launch point. Be ready when the rope arrives. It's no different than when the tow plane returns. At one UK club where I winched, if you were staged, you were ready to go when the ropes arrived. If you were still fiddling, you'd be pushed to the back of the launch queue. We typically got 1600-1800agl and I could count on one hand the number of re-lights I took each season (long wings help;^). At another club, we were very lucky to 1100agl on the winch. No tow plane option either. Still got long XC flights from those modest launches. But, I've also been known to jump out of the winch queue to snag a tow from a transiting tow hook;^). CCSC is rather short and I think they've defined their goals with a winch there. Red Stewart Airport is 1.5 miles away, but IIRC, there's too much weekend traffic to winch effectively, so they've done it weekdays only. It might be possible to park the winch 1000ft off the end there, but expansion of CCSC's gliderport would require property acquisition and a new road, both expensive and probably unlikely prospects. Thinking 'way outside the box' the largest privately owned airport in the US, Wilmington AirPark, is 16 miles away and owned by DHL with an uncertain future. Sure would be interesting if there was a place for soaring there, but that's pie in the sky, because the real estate developers are already circling to pick it apart. None ridge sites with short runs have passed along their winches to others in time. Establishing a new glider port with a winch may encounter less nimby problems than with a tow plane. I suspect some at CCSC will never accept winching for themselves. I hope they will accept it for others. Frank Whiteley |

A few of points:
1: The mixed traffic problem is an everyday occurrence at many sites here in Germany. This is a planning and education opportunity. See: http://www.fsv-karlsruhe.de/fsv/serv...menuSelect=270 for a site where simultaneous power and winch launch takes place. Look on the BGA site for more sites in English. 2: Cost? 15$ per launch is pretty high, but as this is a "commercial" winch operation that is probably unavoidable. At our club we have almost 15 years of cost information and our launches are 4€ (about 5-6$) and this includes long term capitalization for rebuilding the winch every 10 years (as we are about to do this winter). 3: I consistently get 1200-1500 feet from our 3200 foot field and looking at my logbook my average "escape" from pattern height is about 70% (stats from after I got my license). Our field is in an area with suppressed thermal activity and we have no consistent "house thermal", with a house thermal these rates would be better. And, I must confess, some of our better pilots have rates approaching 80-90%. 4: We offer ab initio students a deal of 300€ for flights and training to solo. Of course we have no cost for instructors as they are all volunteers. This is a revenue neutral proposal for the club for most students and even when it is not neutral it is still a good recruitment tool. I know that the costs would be higher in the States but this is to give some ideas on winch use. 5: Most students here in Germany learn to fly using a winch and go to areotow later in their flight training. Some clubs give the first few flights using areotow or a motor glider to speed up the learning and then go to a winch. We only have a winch but most of our students are ready for solo after a few months and certification after a season. Of course we lose many at this point because the German written test is very complex and we don't have the "weekend Ground School" programs that are available in the States. Also, I think (WAO) that users who learn from a winch feel much more comfortable and may be safer when flying low i.e. "scratching around low" as they spent their first 50 flights mostly below 1000 feet. And of course they must learn to thermal away from this height to be able to fly longer. You will always remember your first climb out in a thermal you accomplish, maybe better that your solo. I can certainly remember mine :`) Bob |

Bill
Unfortunately I can't. As my Deutsch skills only allow me to order a bier, find the restroom, and get authorization to transit airspace I have a hard time with researching the stats. I will ask and see if I can get them. Frank 2800 feet is still enough for a 1000 foot launch in a plane with a cCG hook. Good for pattern work and landing practice. And as landing practice is the most expensive cost of learning to soar {all those pesky areotows just to get lannding practice :´)} a winch launch is a good way to get landing practice. On a good day, i.e. no thermals...I could get 6-10 landings during my training at a cost of 35€ (before our clud had it's ab initio deal). And, let's face it, to be a safe soaring pilot landing skills are paramount! Surfer Don't know as I have never ridge soared off a winch launch but it would be great! I think that most pilots would be safer if they learned to fly at lower heights(AGL). If you learn to fly correctly at 1000-900-800-700 feet, the procedures for flying at these AGL heights should be the same as those for higher flights, the views are different. At some point early in your soaring career you will be at these heights, and of course you will be within reach of a landable field, so you may as well have a lot of practice. I certainly still have a habit of getting low once per long flight. Pick a field, circle in 0 lift, circle, circle, .5, circle... .8....1.0 and away I go after 30 minutes or so. These issues are CFIG issues. If your instructors were comfortable with winch launches then everyone would be comfortable. I don't know how you get a core of instructors winch "savvy" unless you all get together and send a bunch our way :-} Bob |

Email to: ramwater at uk2 dot net FWIW, I was lucky enough to learn auto-tows (not quite the same as winching) from John Campbell back in the mid 1980's. We rarely got above 700-800 feet AGL, but this was actually IDEAL training for students getting close to solo. It forces you to develop a very good "feel" for the pattern and requires a certain amount of flexibility when things don't go quite as planned. Plus, you can operate with only one rated pilot, eliminating the "no tow pilot today" problem which happens in many smaller clubs. If I were king, I would have an operation that used both winch and aero tow. The winch comes out first thing in the morning (no reason not to start at 7 a.m. on nice summer days), and your students who are ready for landing practice get 3 hours all to themselves while a) the neighbors get to sleep in and b) the students don't burn huge holes in their wallet. Round about 11 am the towplane fires up and hauls some early students who need airwork as well as the XC guys who just HAVE to get going now. Tow pilot takes his/her lunch break around 1 pm and the winch gets going again to work with more students as well as those cheapskates who just can't bring themselves to spend $50 on a 2,000 foot aero-tow while they can get a 1,200 foot winch launch for $18. Sorry Rolf - not really answering your question. I guess the only point is that it's not "either-or" and there are certainly many pilots (students or folks who need to just stay current) who would benefit from more landing practice. Erik Mann |

Bill Daniels- Hide quoted text - - Show quoted text - I tried to get these figures from the DAeC - no luck. However, I got the statistics on glider launches split into aero-tow and winch launches in the state of Northrhine-Westphalia (my old stomping grounds). This state is not the most active soaring area in Germany nor is it blessed with superb XC conditions many days of the year. The overall number of glider flights is slightly declining but the split between aero-tow and winch launches is slightly growing in favor of winching. There are many fields similar in size of CCSC in this area which winch exclusively due to housing developments growing ever closer to the field. Uli Neumann |
