а данных по США - Японии нет, случаем?
США есть в табличке - AAF.
По японцам в начале войны:
Primary training was conducted by
11 Combined Air Flotilla and lasted six months. Pilots accumulated between
44 and 60 hours of flight time in the
K2Y biplane
trainer (later replaced with the
K9W "Cypress"), with officer candidates logging more flight hours than enlisted candidates. Primary training was followed by four to six months of intermediate training in the
K5Y "Willow". Here the students logged an additional
60 to 100 flight hours. Graduates were then assigned to an aircraft type for operational training with one of the training groups of
11 Combined Air Flotilla. Operational training lasted at least three months, and by the time it ended, officer candidates had logged about 400 hours of flight time and enlisted candidates at least
254 hours.
Т.е. в итоге набирается не менее
390 часов.
Japanese Army pilot training was somewhat less demanding than that of the Navy. The complete training course took two years and pilots graduated with
300 hours' flying time.
В конце:
By late 1944, a new Japanese Navy pilot graduated with just
40 hours flying time, while his American opponent had at least 525 hours flying time.
The Japanese Army was likewise forced to reduce pilot training to
60 or 70 hours' flight time by 1945.
Т.е. японцы в начале войны были самыми обученными в мире с большим отрывом а под конец самыми не обученными с большим отрывом.
