I've been wondering for a while now exactly how much of what is on the atpl course is actually used on a day to day basis as an airline pilot. I know that all the things taught are important for a pilot to know, but when you come into work in the morning and go through your day how much of what you learn for the atpls do you actually use? I know from listening to airline RT that much of the Comms exam seems to be forgotten(not that there was that much to learn), and the books themselves seem to suggest that you dont have to do mass and balance/performance calculations in a major airline!
I was told recently that Gen Nav is largely left in the exam hall or isolated in some dark recess of a pilot's mind only to be recalled during sleepless nights or cold sweats.
Having a knowledge of all the workings etc is good and can save one's ass I know...but still....I'd just like to know how it really is on average!
