He is right. I forgot that most 320/360 builders have not finished the boot/leg area as I have and many cowlings drop down further (bottom or rear mounted throttle bodies) than mine - thus their leg door is hidden inside the cowling. All I need is a 2-3 square inch door only on the fwd side of the leg (bottom when the gear is retracted) to seal the gap betwixt the glass gear door and the leg and it is exposed below the cowling when the gear is down. I suspect that I have some leakage of cooling air into the wheel well, even though the door is mounted, and that such heated air exits via the trailing edge of the nose gear door. Because my door was recently rebuilt with stiffer carbon fiber, this may no longer occur. I will use a temperature probe to report on the temperature in my nose wheel well during flight. It is important to keep the leg hole small so that during your flaming descent to landing with the gear down, only a little bit of the fire is trying to burn thru the wheel well.
