The ranges in the attached map look believable. As for the A&A rules – any version of them – I consider the travel ranges of all the units (planes and ships and ground units) to be abstractions more than anything else. There are a couple of reasons for this. In terms of space, the A&A maps are not only distorted (in both size and shape) relative to the geography of the real world, they’re unevenly distorted; in Global 1940, for example, China is highly compressed east-to-west compared to its north-to-south dimensions. In terms of time, a game turn doesn’t represent (as the attached map does) a single airplane sortie but rather a span of several months – and an imprecisely defined one, for that matter. In tactical-level wargames, which operate on a much smaller scale both in terms of time and geography, it’s possible to have meaningful range accuracy, but as far as A&A goes I think that the best that can be achieved is to give units a range that looks vaguely plausible on an impressionistic level.
