Default All US Records are Now Motor Glider Records

I understand the difference in the mental game, and the additional pressure it places on you. It is one of the reasons that I bought this new toy. I have some records I would like to go for this year. To mount these attempt I would need to arrange for early morning launches, have a crew on standby, etc. All posable, not all that expencive, but asking a lot of other support people. With a motor glider, I can provide all of that myself. In that these will be wave flights, I may face the possibility of an airport landout, to warm the motor back up, but I will be able to self retreve. But assuming all goes well, I can do that without inconvenience to others.

So now we circle back to the advantage of "convenience". It does not seem appropriate to have diferent category based on convenience.

I could have all the piece of mind, and comfort if I had a ground crew following me on an attempt. And I might note for the price of a new motor glider that crew could be paid and bring the drinks and dancing girls in the back of the chase limo. We might look down on such a well funded record attempt but should it require a new category?

Doesn't an engine and the having the additional "arrow in your quiver" allow you a bit more ability to take risk?

No it does not. Without the engine, I would continue looking for thermals down to 1000 ft. (in the West, some in the East would say 200 ft). With the engine, 2000 ft. You need to get it out, go through the start up routine, warm it a little (on cold/high days), then when it DOESN'T start, put it away again and line up for your landing.

Yes there are people who don't do this - the NTSA accident database is rife with them. Statistics argue that the engine makes the glider more dangerous, not safer. But more convenient - when it starts - and the safety is subject to the full control of the operator by showing some restraint.

A second drawback so far unmentioned is the pilot workload that the engine contributes to, at a very inconvenient time (you are are low). Should I start the engine? What if it doesn't start? Will the 50% degradation in performance once the engine is out preclude the landing area I chose? Do I remember the exact sequence? Should I have started it 5 minutes ago? That extra bit of distraction, just when you are near overload, is a significant factor in the prudent decision to give up earlier.

The reason the mindset is different with an engine is that it is sunk cost, so in the middle of the day I will go further, knowing that 9 out of 10 times the engine will start if it is needed, and the inconvenient retrieve is reduced to 10% of the consideration it might have been. The money has already been spent, whether I use it or not. In my engineless glider, in the middle of the day, I am thinking, "do I really want another 50 miles if it is going to cost me $300?" and often the answer was no. I hadn't yet spent the money, and there was the opportunity to save it. This has nothing at all to do with performance. My suggestion to those without an engine, who want the extra 50 miles on a day with landout risk, is to hand $300 to your ground crew, Uber driver, or whoever before you take off. Now go fly. They will come get you if you land out. You don't get the money back in any case. Now you can have the same mindset, along with the satisfaction of knowing you can do that at least 10 times a year and still be paying less than the cost of an engine.


Back to records. The ability to be able to selectively end your soaring performance at will, in the air, is a significant benefit to the pilot. All this huffing and puffing about the prudent use of TODAY's technology is relevant to precisely nothing as far as the *rules* go. As the technology improves, I expect to see MG pilots do even dumber stuff, and mostly get away with it as they do now.

Now off to wax my xc skis.... (on ST Patty's day? argh).
