CM:
Q1 Who said I would take 150kg?
Q2 None, but I do not consider the number of engines relevant. Also this 'obsession' with 'hours' again - 5% is 5%
On nearly all my flights, including trans-Atalntic, I have RARELY used all my contingency. I have generally found that wrong winds/levels/routings etc all sort themselves out somewhere in the great 'averaging' scheme. A few have been 'nail-biters' as this one was.
Are you also saying that your '4 engine long-haul' regularly eats up all your contingency?
