The advent of GPS pretty much signed the death warrant for MLS, enicalyth, so I doubt that there's much of a market for it these days. If this place is 180-minutes ETOPS, that's a worry. Are there any adequate/suitable aerodromes nearby?
And, if the shorter runway is operationally necessary at the time, what happens if it's blocked by an aircraft involved in an incident or accident? The longer runway would be needed and, by the sound of it, the weather would need to be favourable. This is startng to look like a real nightmare.
Sounds like a 737 mightn't be able to carry enough fuel for the requirements of this place.
