When we were discussing the DG Mandl extractor air vent some time
ago I think I mentioned that the best location would be on top of
the fuselage in the low pressure area.
It seems either somebody saw that or had the same idea. Blending the
vent tangentially to the rear was always a good idea and is commonly
used in engine cooling. Nice touch to add the louvre. This looks far
better than the relatively crude DG vent. Might want to organise
something so rain doesn't get in though.

Furthermore:
Might be an idea to see how much suction this produces and the effect
on your flight recorder pressure altitude record.
