You are going to claim you are correct despite the fact every other word in your argument is "temperature". Really?? 
It is retarded.
Again, call Lycoming.....
Their customer service will answer your questions and you can argue with them and the FAA. |
No one denies that engine power depends on density on the manifolds, however, the argument was if the FTH depends on the density altitude or the pressure altitude in the case of the Merlin. As pointed out earlier, the supercharger of the Merlin keeps constant pressure up to the FTH regardless the density of the air (indicated by temperature), so it's clear that the FTH depends on pressure altitude, just like in the case of the radial engines with similar superchargers in the USAF handbook.
I end this discussion here, you just keep flossing a dead horse...
