I believe the E11 and E33 error messages are normal when the unit is powered
up in flight. I have seen those myself and was similarly worried until I
looked them up in the manual.

Subject: [LML] Re: AOA issue

Flew down to Hyannis on Friday afternoon and I was a very unhappy AOA
camper. During the 20 min flight, the AOA Pro display became quite dim, and
I was seeing numbers on the bottom that were fluctuating between 150 and 200
in level flight. I pulled the breaker and reset and got
E11 and E33 for error messages. I never see these error messages on power
up. Later in the flight, the display appeared to be functioning normally
again. Back in the hangar, I checked the upper port drain valve and got about a
1/4tsp of water. The 1hr test flight this afternoon showed the AOA to be
functioning normally again. Hard to imagine that small amount of water could
be the culprit though. I'm thinking now that I should disconnect the
upper/lower pressure port lines and apply a bit of compressed air to be
certain they are free of any moisture.
