Re: Europa-List: Re: Cabin fresh air exhaust

I´m considering fitting a small air exit at the cockpit side where due the effect of wing´s top curvature there will be a negative pressure gradient. Also, I could be slightly turned down and after so to avoid water entering from rain.

Because you may find that the air pressure behind the D panel is higher than the cockpit and so you will simple see air coming from the rear to the cockpit unless you have some arrangement in the tail to lower the air pressure in that area.

In my aircraft that is what happens, Trigear XS.

Seems you'd just install an adjustable vent or two below the D panel and an exit one near the rudder. The air is going to get to that exit with or without the tubing.  Then test different adjustments in the vents until you get a setting that best matches your most used altitude. Wrong?
