I
was persuaded by the arguments cited on the List in favor of an AOA
indicator
and just received a Dynon AOA Pitot tube to replace the
standard AN5812.
It's 2 1/4 inches longer than the AN5812, and so sticks out a couple of
inches
in front of the leading edge. In the installation instructions Dynon
recommend
that the tip should be between 2 and 12 inches aft of the
leading edge, which would mean I need to move the mount aft to outboard
of the
gear doors. This would be a pain, and would also result in a longer and
circuitous route for the pitot and AOA plumbing, as would mounting it
at the
wingtip, etc...
Chris,
I have this system installed in my Lancair IV-P, and have
been very pleased with its performance—except for a computer
failure—which
Advanced Flight Systems replaced under warranty. I believe having the
pitot
tube extend forward of the wing leading edge will not affect its
performance,
and may, in fact, improve it. Not being an authority on such, however,
I’d
suggest that you call Rob Hickman at Advanced, (503) 263-0037, or email
info@advanced-flight-systems.com
about this. I’ve found them to be most helpful and am sure they’d
be willing to discuss.
Good Luck; your decision to use an AOA is a good one!
Bob
