Managing delays
schlong hauler
Fair comment. It's some years since I worked in a major ATC unit so I'm out of touch with the current understanding of ATCs for assessing holding fuel. However, I recall that the problem you mentioned - the lack of understanding by ATCs about the SAM operations, has been around for many years and I suggest that the reason for this is because no one ever properly explained the company fuel policy to the ATCs. Some of us were aware of it but only because of discussions with Airline Company Ops and it became a local knowledge issue and not a national one. Additionally, at the time I understood that different operators had different requirements.
I would suggest that you pursue this one through formal channels with Airservices. They have a National Operations Centre which handles such matters.
Good luck
