Can someone tell me why the air coming in the standard cabin vents is hotter than ambient?
Before you speculate....take a temperature probe with you and stick it in the vent while flying and compare it against a known outside air temperature.
Is it heat of compression alone? boundary layer ingested air from the cowling? heat leaking from around the cowling hinge (mine is fairly tight but i guess it could still leak some)?
