Credit must be given to the UAE controllers, they do call us ASAP and let us know that a particular A/C needs to be dropped.
We then have (some) time to get the pilot to check with their ground ops/ handling agents and fire through another copy of their flight plan by fax, most times it actually works and they get to stay up.
Maybe the plan is there in the UAE but someone forgot the "W" in the equipment list when they filed it, again the controllers are screwed, the directive comes from above.
Can't explain this away if repetitive plans are filed, maybe they get lost internally at AUH centre?
