O.S, thanks. I'm not a performance guru just a driver endeavoring to gain a bit deeper understanding of backgrounds. I just take it for granted with a healthy portion of skepticism, of course, what the performance layout says. All I can tell is that those EO procedures are designed for all the fleets from 320 till 346. for each and every RWY. So yeah, it's all about how serious the operator is about those things, I suppose.
