Yes, I am a long way from the UK market but it is a recent move so I still know what is going on there. My point about size was really more about equipment and complexity.
If you are Multi Engine, IFR, ATPL, with lots of experience, then you should command a higher salary than if you are a VFR 206 pilot doing charter work. The two markets are separate. The Multi Engine IFR pay rates will be dictated by the biggest users of those skills and requirements, ie the North Sea Operators. If the North Sea sheds pilots who have that ME experience and they become available on the market, then supply and demand will dictate that the pay rates will remain low.
As I said before, when pilots were leaving the North Sea to go fixed wing in 1987-88 in big numbers, salary scales went up by
15-20% and the whole industry, offshore and onshore, had to lift their game. The North Sea Operators, therefore, need to increase salaries before you can all earn an extra quid and that won't happen without a united approach.
