Agreed-I'd be looking for the improved single engine performance-I also remember there being something written on a previous type that you could safely take it above V2........but have'nt been able to find anything in my Boeing books.
Now that begs the next question-TO 1 take-off with an assumed temperature of say 45 degrees. Airborne and you press the TOGA buttons. Does it delete everything and you've got Max TO, or does it just delete the assumed reduction and leave you with TO 1?
