"Level Flight Attitude"

[Robert Andrews]

Hi,

The Weight and Balance section in the Elite manual says to put the aircraft
in a level flight attitude. Yet, no where does it say what that is - or at
least if its there, I haven't found it yet. For certified aircraft, the
TCDS defines how to get a given aircraft in the "level flight attitude"
(e.g., plumb from one point to another point). Since the bottom of the wing
is a few degrees up from the cabin floor, I would tend to think when the
cabin floor is level (for and aft), the aircraft is in the "level flight
attitude" w.r.t. pitch ... but would like to actually read that somewhere.
Asside from getting the W&B correct, this impacts calculating where the step
goes when rigging floats. Because the distance is a fair distance between
the bottom of the wing and the float step, A plumb line down from a given
%MAC (e.g. 45%) from a improperly rotated aircraft will result in the step
NOT being where you planned to put it. So, what defines the "level flight
attitude" for an Elite? ... and other Murphy derivitives?

Cheers, Bob 612e
