I'd like to rescue MkVIII a little (he needs a hand lately - foot in mouth syndrome
) He deserves it.
Landing the DC-3. Assuming the pilot has correctly crossed the threshold at 50 ft, and correct approach speed and such, a wheeler landing WILL, as HSWL says, give a shorter landing DISTANCE. A 3 pointer will require more DISTANCE (float etc), but the ground roll will be SHORTER. So, it is 6 of one, and half a dozen of the other.
Now, if you flew the -3 at the arse end of the speed / drag curve, and 3 pointed it, you could make the girl land SHORT, and I mean SHORT! But, GREAT judgement, skill, and attention required!
TAA SOP was as mentioned 3 point everything, until one TAA PIC managed to do mischeif to a DC-3 at Forrest, WA. Then, TAA became the Wheeler Airline!
I do NOT recommend retracting flaps on landing to dump the lift and weight the wheels in a DC-3 - a certain pilot in PNG successfully raised the gear on landing instead of the flaps - the handles look almost IDENTICAL.... of course he was fired for it, and went to the opposition.
It is NOT a good thing in ANY aeroplane, even with 2 crew.
