Max bomb loads to distances for BC 4 engine bombers

[Graham Boak]

Bristol-engined Halis, not P&W. I have some but it may take some digging out. Is your consumption figure at full load or empty? I have done this sort of thing professionally (although not on Halifaxes and Lancasters!) and simplified assumptions can lead to misleading results.

The back of the Air Britain Hampden and Stirling Files do give range with different payloads, in what looks like an official format. I'll try to check over the weekend if the equivalent data is in the Lanc and Hali Files.
