ABSTRACT
Domestic flights are authorised by the government in question, and are subject to movement controls prescribed by government-empowered providers of en-route air navigation services, and by local traffic control services. In Australia, a government-owned corporation, Airservices Australia, has focussed on first introducing ADS-B communications linked to ground stations. With the required ADS-B equipment installed in about 1100 aircraft approved for operation in Australian airspace, the new system brought immediate and unequivocal operational benefit, when dealing with equipped aircraft. Standard runway charging methods, notably pricing according to aircraft weight, have no regard for those aircraft delays. A practicable rule for pricing of runway congestion needs some approximate, simplifying assumptions. During the peak period, the number of aircraft in the queues will vary. In order to implement the economic principle, the agency responsible for setting runway access charges needs to be able to estimate the additional delay costs imposed on all other aircraft movements.
