Flights with a specific character (hereafter 'special flights') require additional co-ordination between the applicant and the air traffic service concerned (also see AIP Netherlands ENR 1-2, paragraaf 3.2.5) in order to prevent any unclarities during the flight. To ensure as little RTF as possible on an active frequency, intentions are considered and agreements are made before the flight has started.
The Operational Help Desk functions as point of contact for the pilot, co-ordinates the special flight with the air traffic service concerned, and reports any additional requirements to the applicant.
