Some years ago before retirement, my management 'encouraged' plog fuel. One day I got back after a flight to see the fleet manager filling in a report to explain why he had shut down with less than the required minimum fuel. In conversation he said to me;
'who would have thought I would have had to fly the hold for so long at this time of day on a Saturday?'
My reply was me. I expected to hold, and indeed had carried some extra fuel on that day to do just that. I said that I made decisions based on the experience of flying 4 or 5 times a week, as opposed to flying a desk and only arriving at an aeroplane in order to keep currency.
I may add that I was way up the seniority list with months to got to retirement!
