Antigua,
I actually work with the Director concerned, and there are some things that you have incorrectly assumed.
The MOR was submitted not because he had his nose put out of joint but for exactly the reasons stated by other ATCO's.....that your aircraft was in a position where you had declared how low on fuel you were.........your action of informing him was appreciated and he was grateful for you doing so. He was in no way annoyed or upset by your information. However he was absolutely correct to enquire as to what would happen if you did have to go around...........what if the previous lander, burst a tyre or had some kind of landing accident?
Reasonable question surely?
Your email however has been doing the rounds at work, and I can assure you that your comments regarding the LL Directors lack of suitable final approach spacing have not gone down very well, and neither did the tone of the end of that mail. Contrary to your belief most go-arounds at Heathrow are not caused by inadequate final approach spacing..........which is FYI done superbly by very skilled people in a very intense situation.......I would challenge you to do an hour of LL FIN. The majority of goarounds are caused by late runway vacations.
As has already been stated on here, operating as a regular into Heathrow, I think it is misguided to put oneself in a position where one does not have enough fuel to make at least one go-around without getting into a drastic mayday situation.
Some of your assumptions and comments about my collegue have not been appreciated, and have been read and noted by the controller concerned.
