BOAC
Your quote” I once flew with a Captain who carried 1000kg on a Cavok day 'because it is nice to have a bit extra' and then carried 1000kg on a Cat 3 day - for the same reason. That, to me, is bordering on lunacy”
I thought I was the only one that had witnessed/experienced this lunacy and I’ve had F/O’s try to do the same thing. Monkey see, monkey do I guess.
On the other hand I’ve also experienced dispatchers trying to put on tankerage fuel when the weather conditions at the departure airport were less then desirable due to slippery runways etc. They didn’t seem to understand the concept of trying to stay on the runway surface in the event of a RTO. In marginal conditions having all that extra weight on T/O certainly wasn’t going to make my job of stopping or handling an engine out any easier.
Bottom line; use your common sense when requesting additional fuel, don't be a monkey...
