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).

Bill,

 

Good information Bill.  Thanks.  

 

You are flying a 320 airframe?  If so, full flaps on your airframe are (30 - 40 degrees?) significantly more than on a 235 airframe.  As I have mentioned several times on the LML top hinged (standard construction) full flaps on the 235 are about 23 degrees static and about 19 degrees in flight from neutral.  I consider the difference noteworthy in pattern flight.  I wouldn't recommend 70-72 KIAS round out speed at 19 degrees flaps. 

 

Your info doesn't indicate whether you are solo or with passenger.  In my 235/320 (I never pull the throttle back to idle on final until on the runway), with a passenger, I cross the fence at about 90 MPH (78 KIAS) and round out in ground effect at 85 MPH (74 KIAS).  70-72 KIAS (81-83 MPH) is the minimum I would ever use in the round out.  That and anything less and I risk dragging the rudder from the increased angle of attack (ventral fin and shorter 235 gear legs).
