Given that this post, and a previous one concerning climb performance (particularly CLIMB derate policy), have recieved little comment, I would be grateful if people could indicate which of the following statements is true.
i) No-one has any opinion on this subject of climb performance and CLIMB derates - hard to believe in todays economic environment
ii) Every operator uses full MCL rating on every climb irrespective of aircraft type, weight, flight condition and local ATC restrictions
iii) No-one is interested in climb performance and CLIMB derate (a risky option to include as I'm sure it will be the subject of some very clever and cutting sarcasm)
I would be even more grateful for any information on the subject
