Many if not most Bonanzas don't use flaps even for short field and
this didn't look short.


The standard Bonanza takeoff is no flaps however using flaps does reduce
ground roll. For an F33 at 2800 pounds on a 32 degree day at 5000 feet
as an example using flaps shortens the takeoff roll. However the no
flap takeoff only needs an extra 70 feet to get off the ground. By
3400 horizontal feet the no flap takeoff has crossed the altitude of the
flap takeoff and is significantly outclimbing it. So the question you
ask yourself is are you trying to get over an obstacle close to the
takeoff point of farther away? If the obstacle is close use flaps, if
not then don't. For the takeoff in the video no flaps was correct.





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.


My S35 does call for flaps to clear an obstacle.




As to gas, the capacity varies over a wide range. With a newer plane
it varies from 75 to 100 or so depending on the tanks installed and
the size of the Aux tanks.. I can put 600# of fuel in mine and with
1000# useful load it's at best a 3 passenger plane if they are skinny
and no baggage. The F33s reached 1400# useful load so depending on
lots of variables It may or may not be a 4 passenger plane.

They reported it to be a 4 seat, but it sure looked like an A36. Try
as I might I could not come up with a valid N number to check. Nor
could I find anything listed for a Walter Norwood.



It's a mid 70's A36 which would have 80 gallons onboard assuming no tip
tanks.
