Sounds sensible.
If we take the 'Gate Position' method of 1nm, 500ft as being a safe approach method, a basic weather minima of 2nm 700ft would seem appropriate. Any weather below 5km 1,200 ft requiring an ARA, and of course crews may elect to carry out an ARA approach no matter how good the weather.
This should ensure that crews have a visual 90 second 'level sector' at 500ft in order to obtain good visual references before reaching the 'gate'. After the gate you would still expect a further few seconds level flight before descending on the sight picture, rugby ball, CTB or whatever you want to call it.
We still have to overcome the fact (as perhaps in the Etap incident) where imminent local weather is not always visible to the crew until you fly into it. There is also the difficulty in flying and monitoring that last 20 seconds as you transition back to the hover and position over the deck. Not to mention the question ............. Do the oil companies really require these crew change flights at night or would it be considerably safer just to move them to the weekend where there is plenty of spare capacity.
