Graeme,
I found the Naca vents did not flow enough air for me on hot summer days so w
ent down the standard aircraft practice used for Sailplanes and Motorgliders
( derived from a ww2 requirement of all aircraft supplied to military to hav
e a direct view panel in case of oil coverage or icing ).
I enjoy flying in the winter and during a dawn takeoff from Elverum in Norwa
y snow covered strip , the canopy totally iced over as we climbed out , we w
ere able to use open DV panel to circle the field as the rising sun melted t
he ice and restored full view..
Window needs to conform to shape of screen ,
Mould taken from exterior of screen before I laser cut the window aperture .
The location is high enough so the ram air vent clears the door handle.
And is as far forward as the slide rails will go against door frame .
