Hey Lynn;
Who makes those kits to change the canopy hinging.  After all of this 
discussion, we are considering it.  Also looking into Halon fire suppression 
system for firewall forward.

Skip,

You asked:

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

During flight the largest force keeping the canopy from being opened is the
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 possible
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.

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
