How to get FLEX and TOGA Thrust to work.
Posted: 12 Nov 2020, 02:25
When I try using FLEX thrust, the engines always spool upto 97% N1 approx. regardless of what value is set in FD-FMC takeoff page. Furthermore, once I reach FLEX detent, I can still increase/decrease thrust without changing the detent to TOGA or CLB (albeit only by a little)?? It is my assumption that the thrust must be fixed? Can someone please explain how the ATHR logic works for the PA A320 on takeoff?
