Alfred, I'm curious on the dive bomb training. Why is it set at 14,000ft? I've been training at 10,000 assuming that the recommended bombing altitude would be best.
I use 14k because it is within the dive bombing altitude envelope and helps to safeguard against forgetting to assign the dive bombing altitude if I place the dive bomber unit on active duty. Any altitude within that envelope would do. Essentially I treat it as an aide memoire.
I find I incur minimal operational losses irrespective of what altitude I train at. Even at 100% training for 6 months my operational losses remain minimal, so I am absolutely unconcerned as to the fatigue levels. I am most scupulous (a) to not have a unit training beyond its normal range, and (b) there is at least 1 aviation support for each plane (whether on training or on active duty) at the airbase. For example my Beaufighter Ic were set to train 100% at range 9 and did/still not/do incur any training losses, even after months of training.
If you want to be ultra conservative, the advice given by others to train at range 0 etc will maintain operational losses to acceptable levels.
Alfred
