One question to those in the know, please.
From the previous posts, I gather that the procedure is as follows: for each individual flight, the Commander (or the company) decides on the MTOW du jour; the flight will then be loaded, fuelled and executed according to this number.
But what next? Will the company compile a list of each flight against the used MTOW and send it to the authority every so often so they can be properly billed? And to which authority will that be - seeing that Eurocontrol seems to have no knowledge on different possible MTOWs for one fleet, it seems that for FR, the Irish CAA or ATC provider is the recipient and then just hogged this information?
If so, the hot water FR seems to be in will likely be shared by this authority.
