Stobart Air operate the aircraft to the same limits as everyone else ...
the majority of problems on the IOM are weather related and the fact that the ILS operates to increased CAT I minima due to their being no approach lights on runway 26. The runway was extended and the approach lighting gantry not replaced, so rather than the standard 550m RVR required on the IOM it is 1,000m
Given that the weather is frequently 500m or below, that causes the vast majority of problems (such as yesterday).
If the airport had a CATII ILS then everytime I have had a problem and had to divert, we would have got in.
It is not the aircraft, or the airline that is the problem!
