Lynn,

Skip,

You asked:

"Is it possible to bail out of a Legacy (or 360) with a forward hinged=20
canopy?"

During flight the largest force keeping the canopy from being opened is th=
e
air pressure created by forward airspeed. What would happen to the air
pressure if the forward airspeed was reduced or actually zero?

In answer your original question, I suggest to you that is would be possib=
le
at very low or zero airspeed. Just pull up into a steep climb, reduce the
airspeed and just before the plane stops going up, push the canopy up and
step over the side.

Or, perhaps you might use negative "G" to help exit the aircraft.=20

But of course my Legacy has an aft mounted canopy so all I have to do is
unlock it and I will be able to exit.

Regards,

Lynn  =20
