If Helinuts reference to the delay at Luton is the flight I beleive it is this suddenly becomes much more fun.
The Operator had been contracted to pick up 2 pax at Luto, 2 Pax Battersea Heliport and then take them to view a "facility" at Heathrow.
For both the Airports the Operator is required to "book in" with a Handling Agent. The Handling agent then deals with all the logistics and communications to arrange the landing, the Operator is effectively out of the loop. The Handling agent chosen on this occasion was also the owner / Operator at Battersea and the owner of the facility at the GA terminal at Heathrow. One agent - All nice and tidy you'd like to think.
However, at no time were the Helo Operator advised that they were subject to a "Slot" time, and even though both the pilot and his Ops team (phone and fax) advised the Handling Agent at Heathrow that the flight would be delayed leaving Luton, (note that they have to contact the Handling Agent as they are the only point of contact!), they were never advised of a change to the landing "slot" time or of any potential violation.
They continued the flight as per their plan, albeit some 15 minutes late, and were at no time advised by ATC or any other means that they had missed their "slot".
It was not until some 3 months later that a letter arrived from BAA advising them that all their operations into London Heathrow were banned for the next 30 day's. This was the first notification - no warning, no discussion.
Living under the Flightpath of Heathrow, and knowing several controllers personally, I appreciate how busy ATC are, and am not pointing the finger at them.
My question is quite simple - why was there no communication from the Handling agent ref. the need for a slot time, the potential violation, and finally the actual violation? Also were the Handling Agent penalised in any way for failure to pass on the information?
