The PW-6 has very effective spoilers, and some other gliders have even more effective spoilers. Assuming C.G. is within limits and runway is level, is it possible to round out and flare with the spoilers fully open? Does one need extra airspeed? How much extra? (Yep. I know it is advisable to reduce spoilers before entering roundout.)

How do you teach steep descent to students? How steep? How fast?

I saw this question come up in a discussion of a fatal accident in a SZD 51-1 Junior. Student pilot opened 'full spoilers' and failed to flare.

Is a 'full spoiler flare' required to obtain glider certification in EASA?

And finally, does the PW-6 have spoilers or airbrakes?
