I have just given an explenation to
where the published number 53,200 lbf comes from and how
it is meassured.
Having a standandard day is the only meaningful way
of comparing engine performance, thats why the FAA has these standards.
Not true. And it is, in any case, of no relevance here.
Like I said, the engine will offcourse hit 53,200 lbf (and higher!!) at other temp/alt/N1 scenarios, but that wasn't the point.
That is exactly the point. But one that seem unexplicably hard for you to understand.
You have no way of
knowing one single other datapoint in that diagram that gives
exactly 53,200 lbf unless you get your hands on some thrust/N1 diagrams.
Of course you do. That is the purpose of the chart.
I will agree with on one thing. Barit1 does give an excellent explanation. It's just a shame you don't seem to understand any of it.
