![]() "Wayne Paul" wrote in message ... If my memory serves me correctly, the above requirement of wingspan ^2 divided by gross wt not to exceed 0.62 lbs is stated in the "Certification" limitations. It has been argued that this requirement doesn't apply to experimental air craft. If it did, "Space Ship One" would not be registered with the FAA as a glider. On the other side of the coin, the Windrose meets the requirement; however, you find cases where it has been registered as an "airplane". Communications with the owners revealed that this was done to avoid having to spend the time and money to get a glider rating.

One tiny correction to Wayne's writeup: Dick Schreder's amphibious
motorglider was to be the HP-22, not the HP-21. Here are scans of the original spec sheets for this aircraft: http://www.hpaircraft.com/info/hp-22/hp-22_1.jpg http://www.hpaircraft.com/info/hp-22/hp-22_2.jpg http://www.hpaircraft.com/info/hp-22/hp-22_3.jpg Thanks, and best regards to all Bob K. http://www.hpaircraft.com/hp-24 |

OK, here's a question. Does a seaplane motoglider exist? I'm reasonably familiar with motorgliders, and I' don't know of any. There were some seaplane pure gliders, and I recall at least one plan to build one, but don't know what ever happened. After more than an hour of searching, I found the motor glider specs he http://www.sonex-ltd.com/motorglider_definition.html 1. What are the restrictions on a motorglider vs. LSA? 2. What are the advantages of motorgliders vs. LSP? ...555#'s more MTOW is one. Found this interesting. (Maybe it's out of date already - 2000) http://www.ultraflight.com/difference.htm I'm going to Google rec.aviation.soaring for motorglider info: http://makeashorterlink.com/?M3C732ACB Well, this was sure an interesting discussion over in RA(S)oaring ;;;Can a glider rated pilot fly a non-"self launched" 152/172/Warrior according to the FAR's? Plow through all 36 posts. - interesting. Montblack |

![]() "Montblack" wrote 1. What are the restrictions on a motorglider vs. LSA? None, that I am aware of. 2. What are the advantages of motorgliders vs. LSP? ...555#'s more MTOW is one. Night flight seems to be allowed, and also, no limit on maximum speeds, or minimum speeds. Repositionable props would also be allowed, I believe. If the asinine LSA rule does not get straightened out to allow for repositioning gear in flight, (for amphibians) it would be a way around that. As a possible LS pilot, I have no problem with all of the restrictions of weight and speed, but I'm not certain I can live with no night flight. If they will let you sign off for complex airspace, why not also for night flight? -- Jim in NC |

Please remember that by FAA definition, a glider is a heavier-than-air aircraft supported in flight by the dynamic reaction of the air against its' lifting surfaces and whose free flight does not depend principally on an engine. Meet this definition and you can call the thing you built a glider. Gliders are launched in one of three methods; aero-tow, ground launch (behind an car/truck, or using a winch) and self-launch. A pilot's log book will contain endorsements of each type of launch that the pilot is qualified to perform. What is commonly called a "motor-glider" in reality is a self-launched glider. Gliders with engines come in two types. One has an engine powerful enough to launch the glider. The other has a small engine that will only sustain flight. The latter type are usually found on gliders with a large wing span (20+ meters) that could easily be damage in an off-field landing. If you fly over half the time with your engine on, it would be hard to argue that you are meeting the FAA's basic definition of a glider. Be careful if you are think of calling something a glider simply to avoid the FAA Physical requirements. Respectfully, Wayne P.S. Last post on this subject. |

![]() "Wayne Paul" wrote There are many single engine experimental airplanes that don't meet certification requirements that are flown by licensed pilots. Agreed. But how about a glider rated pilot flying something that is an experimental, that is supposed to be capable of being a glider? I would think that as a glider only pilot, what I fly, better be a glider. Please remember that by FAA definition, a glider is a heavier-than-air aircraft supported in flight by the dynamic reaction of the air against its' lifting surfaces and whose free flight does not depend principally on an engine. Meet this definition and you can call the thing you built a glider. You would have a lot better chance of calling it a glider, if it met the certified definition of a glider, no? Gliders are launched in one of three methods; snip following Yes, I am aware of the methods. If you fly over half the time with your engine on, it would be hard to argue that you are meeting the FAA's basic definition of a glider. Be careful if you are think of calling something a glider simply to avoid the FAA Physical requirements. If I go this route, have no doubt that I will not be *just* calling it a glider, but it will meet every definition of a glider, and might even act like one, too. That is why the interest in the definition of a certified glider. I also would like to be able to operate from a boat ramp, or lake, since I really like the water, and my folks live at a lake. The FAA isn't up there with me, is it? g Besides, I might just be really crappy at finding lift, right? g Really, I have not done any soaring, but it sounds fun to me. I love sailing, and it seems the two would be have many familiarities, I would think. I would like to punch holes in the sky, sometimes, and go places, sometimes. There are people out there everywhere, picking carefully at the FAA regs, finding what they want to find in them, and avoiding what they want. Respectfully, Wayne P.S. Last post on this subject. Thanks for your insights on the subject, and from you posts, I see you do a bit of soaring, also? I think the only real answer I will get, will be the "opinion" I get from the local FSDO. After all, if it is an experimental, they will be the final word of record. -- Jim in NC |

Meet this definition and you can call the thing you built a glider. Hmm...... By that definition, (or close) I think a Taylorcraft BC-12D is very close. I have several logged flights, in a Taylorcraft, of 4 hours or more where the engine only ran for a half-hour or so. We would take off from Pearson Airpark near Vancouver, Wa and head for Mt. Hood. As soon as we would hit the wave, we'd shut the Cont. 65 down and pull up into a stall to stop the prop. Then we'd soar as high as 12,000' IIRC, enjoying the view and the fun of using a peanut butter jar as a biffy. When we'd get tired enough, it was an easy glide back to the airport. We'd coast off the runway where one of us would get out and prop the engine to taxi back. Oh! wait a minute, I forgot. Disregard all the previous polemic. Both Cliff and I only had student tickets, so we couldn't have flown with each other. Heh, heh. ![]() Rich "I know nothing!" S. |
