I recently flew between active ATC regions: Around the world from Casablanca > Melboune > Seattle.
I noticed a recurring theme at these very busy airfields. Many users were declaring “emergency fuel,” with some repeating multiple times. All of these flights were jets which originated less than two hours from the destination airfield (e.g. Sydney to Melbourne). In my view, this is an abuse of the emergency declaration feature. Advanced users should know that fuel planning is part of flight planning.
I had been in an approach hold for 20+ minutes, so I was pleased to see that ATC controllers did not allow the offending aircraft to cut in line. In an ideal world (again, my view), ATC would command the aircraft to divert to a nearby, less congested airfield.
Let me be clear, I have used the fuel emergency declaration in the past on extremely long haul flights (e.g. Brisbane to Mexico City), so I recognize its value. I just sympathize for the controllers who have to deal with incessant emergency fuel requests when they have 40+ other aircraft patiently waiting for their slot to land.
