Again i'll agree with my fellow colleagues. I have never found the FD stressful. Sue there are times of high work load, challenging airspace and weather but stressful is not a word i would choose.
The stress comes from wondering whether you will wake up the next morning without a job. Or debating whether you should buy a house whilst wondering whether you won't have to move to a different base before your house price has managed to repay back all the fees that go along with. You stress about family, relationships and friends.
But the moment you step onto the flightdeck, you are so focused on the job in hand that it is the only place in the world (other than the toilet) where I feel stress free.
