Re: Ju 88 endurance

Fascinating. This is very much the characteristics I was familiar with from jet engined-aircraft, which is perhaps why I remember the contradiction so clearly. I presume that you can confirm that these numbers were obtained at the same conditions of weight and drag. The statement "extrapolated from the curves" has me a bit worried, as such extrapolations have been known to introduce considerable error. (From practical experience...)

Can you explain further the comment about 2000rpm being not ideal? It is certainly true that longer ranges (and endurances) can be obtained by different aircraft settings: low rpm and high boost being optimal. This is behind the tale of Lindberg's advice to P-38 pilots in the South Pacific, although the tale does make me wonder about the attention these pilots paid to ground lectures, or the quality of those lectures. Similarly the light lead-laden streaks behind the exhausts of, for example, RAAF Spitfires in the Pacific.

However, the comments in the PBY manual appear quite definitive.
