Hi! Ferg.
IMHO it doesn't need to exit the fuselage bottom at all if situated
alongside the flap actuating hinge slots. Also in that position the
operation of the flaps will ensure that no "crud" is preventing the
venting working. To have the vent into the air stream pointing forward
will pressurise the system and pointing rearwards could promote fuel to
be sucked out and a siphon starting.

Cheers,
Clear as my mind can be (at times) it has recently rebelled over
a
simple paradox involving vents. I plan a bellyside outlet for the
suction-block bottle in the fuel vent department.
I note also the remarks of several regarding mud and crud along
the
belly due to various manoeuvres, planned and otherwise, during landing
and
takeoff. As a monowheel manipulator, I cannot get the shape of the (say)
1/4inch [6mm] diameter vent sitting out in the slipstream whether the
tip
should be hacked off at 90deg (hipress?), or scarfed at 45deg (top or
botm?)
or tapered horizontally or whatever.
Having had trouble explaining oak leaves and mud on the bottom
of
several Harvards in earlier days, I can't seem to correlate the vision
with
a mudfree vent for my Europa. Your considered opinions, severally and
separately, would hopefully disarm this quandary. Secondarily of course
it
may prompt a vicious and viral debate which could destroy the site for
weeks.
Shamelessly,
Ferg
