Nice, Cannes, everlasting problems since I'm flying into these places.
Nice and Cannes are fully coordinated airports. The particularities are very interesting to study.
Nice is coordinated due to lack of parking slots. Papa apron is used for quick turns and Kilo for overnights (Plan A), then as we all know, our passengers may decide to leave either earlier or later, whatever. This is the gridlock, even if we can request a slot for Nice a week ahead, it will not be granted more than 48 hours at best before, pending the fact that all participating aircrafts are leaving at their respective ETD, which of course seldom happen. And since everything starts from there... Bingo !! Kilo is a "green" sensitive area, and since it is politically easier to satisty 100 persons than to fight 500 employees in the administration, welcome to 'painting by numbers" world, where 20 meters is a matter of life and death for APU usage.
Fuel : only international airport where fuel is coming by trucks from 150 km away, and a limited supply. Fuel people ( very good at painting); have a statewide commitment to have enough supply for scheduled airline ( per law). In order to meet this deadline, they just delay Biz Aviation, this is their management. If you had that during holiday's week-ends fuel trucks canot drive on the motorways, you have the picture.
Cannes is facing the same fuel issue, but their coordination is made for ATC purposes.
what can we do ? Well since all companies are waking up in summer or BIG events, the association, or lobbying group that defend users of Nice and Cannes has very limited fundings and just try to put off the fire when it breaks out. Everyone is welcome to join in order to put pressure onto authorities. ( no it is not EBAA, the local rep has no clue).
If you wish to operate in a smoother way, you have to see it a an ex-ussr operation, arrive at your ETA depart at your ETD (that you gave 15 days before); refuel on arrival, etc...
Good luck to everyone !
