Gary,
I have a fixed pitch prop on my 320. I think I do about 4-5 degree glide with
idle, full-flap, and 72 KIAS. The angle is an estimate, but it is well over 3
degrees. I use 72 instead of 70 to give a little more energy for the round
out. Works okay and I've done it at night (we have a couple of trees on the
approach end and I'd rather risk a bumpy landing than hit the trees).

One item to consider is the type of prop which may be on the plane. Since the plane is a 235 airframe, it is a great possibility that it may have a fixed pitch prop. If that is so, the pilot does not have the luxury of the benefits of a constant speed prop which helps slow the plane down on final and allows for a steeper rate of decent. That fixed pitch prop is always pulling the plane along on final, and throughout the roll out. I would suggest that a good percentage of fixed pitch prop Lancair pilots engage is slightly shallower approaches on final on a regular basis than Lancair pilots with controllable props.
