I am wondering at what Flight Level or Altitude TOGA Thrust will be in-efficient? Since I could not find the answer on FCOM
As EXP CLIMB it stated it's not recommended to use that mode after passing FL 180 (If I am not mistaken).
Thanks for your help guys.
What You are asking is not very clear, at least for me. Are You asking how much does thrust decrease with increasing altitude and its effects on rate of climb or something like that ?
