Robart incidence meter calibration

[John Ferrell]

Unless you are the kind of fellow that wears two watches, never use two Robart incidence indicators on the same airplane. Like the watches, they will never agree!

  Agree, 
  And would add, always set up the level with the same side forward.
  If I swap my robart meter 180 degrees, it's off a bit.

          I don't even try to use the bubble level. As long as you set the fuselage's datum line to what the meter itself says is zero, you can make all your other measurements relative to that reference. It then measures degrees + or - from zero, not from level. Seems to work out OK for me. I do the same for the GP laser incidence meter, which I find more accurate anyway.

          Has any tried to calibrate their Robart incidence meter, or sent it back to
          have it done? The bubble level appears accurate, but the meter is way off
          from where the bubble syas is level. I've checked it against two other
          levels, and the level bubble on the Robart meter is ok.

          Thanks.
