Jabbara…….you have 11 minutes fat before you are declaring a Mayday, being stood down, facing a safety investigation from your Airline, and most likely your Regulator as well. Just call ‘Minimum Fuel’ and carry on with your plan to safely get everyone on the ground. Nothing big will happen, nobody will get excited. The intent of the new calls ( better communication between aircraft and ATC) will have been met and then if ATC do have to give you more holding, or if you have a flap problem when configuring, or if the A380 that’s cleared to line up in front of you takes too long and you get sent around and you call Mayday, then you have met all of your obligations.
I agree that it’s all a bit wishy washy but it’s not a big deal when you are down to lower levels of fuel like that so just do it and the system will work.
