overload,
It doesn't get any easier as it approaches Heathrow. Knowing any significant delay will cause a diversion costing several thousands of pounds. The same potential problem in the event of a go around.
After over a year out of service, ATC is expected to provide the unique handling concorde requires with no practise, training or liason. Some people have become valid in the last year and never worked concorde.
Do you think someone is being over looked here ?
En-route charging is a function of weight and time spent in airspace, does that mean Nats earns less from concorde than a 747 ?
