SND and Geoffers - with you both 100% - train hard fight easy - ASE out ILS was part of a standard IRT on the Sea King - often not pretty but proved the basic skills worked.
Train hard and fight easy - so you ARE still in the mil after all!
Nothing wrong with proving basic skills work, but why not spend the time doing that AND doing it in a feasible scenario. So yes that probably was a feasible scenario in a 1960s era helicopter but it isn't in many 21st century helicopters.
Put it like this the next N Sea crash won't be a consequence of an inability to fly an ILS AP out. So why waste valuable training time on it with the consequence of limiting time on the scenarios that ARE going to be the cause of the next crash?
