Amazing, you don't need to look away for too long before the likes of TC, Crab and Tourist drag this thread back into an RAF v RN v Civvy willy-waving contest and bitch-fest!
On the subject of procedural IRs; surely it's best to train hard and fight easy, if the cab has the required avionics then why not utilise them? Bearing in mind the next generation of SAR aircraft will have a decent icing clearance where would you rather be in foul weather, grovelling around the hard stuff and myriad of obstructions or chilling-out at a safe Flight Level? I've done both and I know what my preference would be, I'm sure plenty of old-school do it the hard way types will disagree though.
