Apart from every other part of your long career you haven't done the test pilot endorsement. My god. Anyway as your an engineer as well as a decorated war hero as you have stated previously when was the last time you had your engine mangment (sic) instrument calibration carried out.
yr right,
You are letting your prejudices show again.
A test pilot approval is hardly needed to exercise native common sense ( admittedly not all that common on pprune) and intelligence.
I am looking forward to your explanation of how you calibrate pulse counter instruments, and the value of relative versus absolute indications.
Tootle pip!!
