In the UK, it never ceases to amaze me the lengths that aircrew go to to keep us safe on the wire. That goes for current contractors and previous military providers. The CAA and previously the MAA and predecessor military authorities have clearly been part of creating these working practices.
Fortunately, in Scotland, unlike Australia, we have the advantage that cold and wind come as standard.
Altitudes do not exceed 4500 feet.
It would be good if one of the guys would step in and give us some detail on the current working practices. (No going to hold my breath.)
