  Marv,
  
  Here are replies to your questions:
  
  1.  All-Red chevrons only, and nothing changed the indicator - including
  very high AOA and very low AOA maneuvers.
  
  2.  Yes, we physically verified all the hookups, and all appeared fine (I
  did the blowing, Bill did the verifying).
  
  3.  We did the hangar calibration inside Bill's hangar.
  
  Only item of significance that I could note was that one of the tubes was
  relatively harder to blow into (maybe the one that indicated on the
  altimeter?).
  
  Thanks, and I'll be calling Rob this morning.
  
  Matt

  [Hi Matt... I'm assuming that the display was showing red chevrons while
  Barking Betty was yelling at you.  We there any attitude that caused the
  display to show changes in the AOA, or was it locked in a high-AOA or
  stalled
  position (ie, entire display lit up)?   Did you physically verify the
  integrity of all the tubing hookups to the AOA computer?  As we discussed
  back
  when you first posted your request, most of the problems Jim and I
  encountered
  in trying to get to the bottom of calibration difficulties related to leaks
  or
  improper connections between the ports and the computer.
