That blind arc is really not a significant problem. Just makes for a few more clearing turns running in to the target - need a decent Nav/Obs!
The mil (especially RN) probably overtrain on the IF side of life - no bad thing for handling but it's a legacy from bluewater ASW days when we spent long-tedious hours getting in/out of the dip. Things are changing here, and the directives will be become more relevant.
Agree that overtraining with no focus leads to complacency & boredom. Those hours don't always have to utilised though.
What %age of the MCA SAR crews (Captains especially) are pure-bred civvies, vs ex-mil? What is their background?
