For those us who can't make it out there, are you planning
on making your slides or notes available?

thanks,

Some bizarre ideas on RAS about motor-gliders!
I did post this, if anyone is interested in,
ya know, facts and experience, as opposed to
Random Aviation Speculation...

Sane motor-glider pilots DO NOT try an air-start
until they have a pattern planned and are in
position for landing after a worst-case failure,
which takes more altitude than landing an
un-powered glider...

Enjoy,
Best Regards, Dave

It's a decent presentation, but I do think "plummet mode" grossly
exaggerates the situation: my ASH 26 E does not have a "plummet mode",
nor do similar gliders like the DG 800, Ventus self-launchers, etc.

My ASH 26 E thermals almost as well with the mast in the cooling
position as fully retracted, and landing with the mast extended only
means using a bit less spoiler than with it retracted. I'd reserve the
term "plummet mode" to sustainers that require diving to start the engine.

For a thorough discussion of self-launching sailplane operation, I
suggest you read my 60 page "Guide", available free from the ASA
(Auxiliary-powered Sailplane Association) website:
