There was discussion some time ago about cockpit ventilation being impeded
by the lack of air outlets rather than air inputs. The problem was that
due to there being positive air pressure in through the flap rod apertures
any vents in the rear of the baggage compartment tended to force air in
rather than extract it.
It has occurred to me that if a small hole is drilled in the roof of the
fuselage at the rear of the baggage bay (after including the necessary
reinforcing) air will get extracted due to the negative pressure in this
area. The hole could be covered with a rearward facing close fitting
streamline cowl to prevent water ingress. Has any one done this or is there
any good reason why it is not a good idea?
