Chris ;

I am interested too with the location of the Dynon AOA probe on a L320.
Let's all LML fellows to know the answer you'd get from Dynon or anyone else .

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...

 

I don't believe I'm the first to retrofit an AOA probe, so does anyone have views or experience on whether it would function well aerodynamically?

 

 

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!
