nowaday's there are very few 'resets' in the air ,or on the ground.They've hidden the CB panels..
At one time one couldn't reset the FCU C/B's in the air..One had to do it ,with the parking brake set for 7 minutes,now of courses thats been changed as well..we got quite 'used' to reset of the FMGC's(one at a time with the flight directors off)..But the reset lists have been around for years and are handy to have..
Cheers.
