Abstract
A verification gauge of this disclosure provides fit-to-pass inspection and visual gauge inspection that may be performed in the field to verify whether an s-type pitot tube falls within predetermined tolerances prior to its use. Verification only requires the gauge. No bench-type vise to hold the tube, no known flat plane (beyond any provided by the block), no protractor, and no accompanying spreadsheet calculations are required. In some embodiments, the verification gauge includes a square or rectangular block that includes four measurement stations or positions that correspond, respectively, to four different tolerances, two relating to face-plane openings and two relating to leg alignments. By positioning the tube within a station, fit-to-pass or visual gage inspection of face-plane openings and leg alignments may be performed.
