Bonanza crash caught on video

Many if not most Bonanzas don't use flaps even for short field and
this didn't look short. As some one from there mentioned it's 4000
feet at 1200 MSL. There is no take off maneuver even short field at
high altitude in mine that calls for any use of the flaps.

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?

I don't know about the Bo in particular, but on some airplanes the flaps
contribute more to drag than to lift. The 182 flaps generate tremendous
additional lift up to 20 degrees or so and then begin to add drag at a
high rate. The Arrow I last flew seemed to add little lift and some
drag once past 20 degrees, but added neither the lift nor the drag of
the much more effective Cessna flaps.

I've never flown a Bo so I don't know what is flaps characteristics are,
but if the flaps mainly add drag and don't lower the stall speed
appreciable, then using them for takeoff would make little sense. The
Arrow performed only marginally better when using flaps for takeoff.
The Skylane was a whole different airplane with flaps 20 on takeoff.
The deck angle was amazing and the climb speed substantially reduced.
