That's interesting -- I never realized that Bo pilots didn't need to
use flaps for departure.
I presume there is something about the wing that makes them
unnecessary?


Depends on the Bonanza - I found that flaps 10 on an S-35 model made a
worthwhile difference to a soft field takeoff (broke ground sooner).


Beech is somewhat deficient in the matter of soft field takeoffs and
flaps. They really don't help you in the manual. We had a fly in at a
friends house yesterday. 1200 foot grass runway. 95 degrees and about
5 knots of wind right down the runway. My owners manual says for a hard
surface runway at that temp and the weight I was at(2360 pounds, 940
under gross) with no flaps and no wind I would need 600 feet of runway.
Manual says nothing about what to add in for a non hard surface runway
or what to subtract for flaps. I know from other publications that
flaps will subtract 20% from the total. The runway surface is just a
WAG but I think the manual from my 182 said to add 8% for the runway.
So that's a net loss of needed runway and since even if I needed 600
feet that's still only half the runway.
Now if Jay would just get the video I sent him last night of the Cub
nosing over figured out you could see a really cool experimental Cub
with retractable leading edge slats.
