Recently, I had the 24 month transponder & pitot/static test performed. All went well with the transponder.
After tightening static fittings, the static test (set @ 29.92 inHg & +1000 AFE) ended with 35' loss (vs 100') and was within tolerance. But, repeatedly the pressure (in the pitot) would not hold (probe drain hole was covered).
Having reviewed VAF & other sites as well as contacting avionics shops, there is varying opinion on the pitot side of this test. One shop says for the IFR test, only the static is required by regulation. And, there appears to be some gray in the regs (which I've read several times!) .
While holding pressure on the pitot side (for 1 min) was the stated purpose, how does that relate to the static test?
The IFR test was run two years ago without issue. Nothing has changed with the pitot / static system over the past two years.
I'm looking for direction on the pitot side of this test. Is it required?
Enquiring minds want to know.
