Whether the tests are 2 minutes, 10 minutes, before first sector, before last sector, short haul, long haul, daily, random or whatever. I think it would be a significant improvement to current procedures.
Imagegear...How would you reconcile the above with the rosters/sectors most of us work these days?
Stick any such test on the start of a flying duty period and it becomes part of that duty period, and could make many ultra long haul sectors or a short haul multi sector days unworkable. By way of an illustration in BA’s case there’s no spare room in the BA T5 area...so if your idea was adopted a pilot would probably have to report to the Hatton Cross training complex (at which point the law demands the duty clock starts running) , do the 2 min/10 min test or whatever it is you are suggesting, then get in his or her car, drive to the crew car park (or take a bus) and head for crew report at T5, possibly via the crew car park ....you’d be adding an hour at the very least onto the front end of duty days and rendering many short haul days rosters and Long Haul sectors unworkable.......it is simply not going to happen.
