Question for Viking, whom I assume is a Hawk QFI:
In my time in the RAF as a QFI, albeit 40 years ago, before we entered the jet the first thing we did was check all seat and canopy pins in place.
Then we kneeled on the seat facing aft and did a thorough seat check, including such vitals as the top latch alignment, attachments of sear pins etc. and correct harness alignment.
It was done on each and every flight, just as we did an external check of the airframe.
Have things changed ?
