Merlin engine limits & failure behaviour

[Viper2000]

How impressively, deeply, illogical.

I never would have guessed. Thanks for the references.

However, this does raise some interesting questions about the lean cruise case, because obviously the interference between mixture and throttle control will limit the options.

I can see this making sense for infinitely variable mixture and fixed pitch prop (since you want a richer mixture at a lower rpm), but it raises interesting questions about the sanity of Camm et al in case of a 2 position auto mixture, not least because you could just use a toggle switch to set mixture if you wanted to take that path. Since Camm was a very clever man, I think that we need to dig deeper here.
