I can't give exact figures off the top of my head but I know the fleet is growing and the number of engineers is falling due to retirement and young lads getting A+P's rather than JAR66 licence leaving for better jobs. My gripe however is when the aircraft lands it is towed off terminal to all points of the compass, only to be towed back again before you get a chance to work them. When parked on these remote stands where APU running is forbidden by the Brothers Against Aviation we wait for ages for ground power to be provided. Result - apparent surplus of staff - playing tiddlywinks - watching their laundry go round in our tumble dryer - because although the aircraft is on the ground for 6 or more hours you never get the aircraft powered up and stationary for more than 2 hours. I'll work out the staff to aircraft ratio and post again, but what do I use as available access time for aircraft on the ground?
