OK, Mathy. Here is the next one (ish) without getting too deep.
Would you expect your ATC flightplan to list your endurance in fleet average fuel usage terms or your actual airframe? You'll gather that I've been out of a longhaul seat for some years.
Additional question. In your present company, would you be given performance-detriment specific ADDs before making a sector fuel uplift decision?
Last one for this time round: remembering forum etiquette
, what would your response be when, after having made fuel uplift decision, you
subsequently found out that on of your 892s was burning 1.5T per hour average more than the other....on a 5.5 hour sector?
