BA handles all flying time as fully counting towards mandatory limits- I believe this is official CAA policy (and quite correct). Without getting into a row about whether this is the correct policy, I would like to say there are reasons why this is important:
1- Such flying hour limits can set limits to exposure to high altitude radiation.
2- The 'off duty' time whilst being relieved are hardly relaxing and peaceful- indeed they are often sleepless, so increasing mandatory limits like this is extremely fatiguing.
3- It is sharp practice to increase annual flying hour limits like this. Why were they imposed in the first place?
Pengitai, I would like to add- you have posted this query in the wrong place- it's 'Rumours & News' right? Read the website holders request. Also, if you are going to pose fairly technical queries like this, it helps if you state in your profile your level or qualification in the industry- it helps with framing an answer.
