How many hours of flight time does a modern day pilot require before he is considered highly trained? Same goes for carrier crew? I was watching the latest news about the first Chinese carrier was launched, but all experts say the carrier won't be combat ready until 2020. That is a very long time. Back in WWII, well entire WWII wasn't even that long. All the new carriers and air groups were put into battle. If they also required 8~10 years training, then there wouldn't be a WWII. How many hours of flight time does a WWII pilot require before he could be put into battle? How long did it go for the carrier crews? Why modern day training require so much longer time? Or was it because in peaceful period people are taking their time? Were the WWII training programs pushed to their fastest limit?
