Motivation for improvement
Aviation Authorities (ICAO, FAA, Eurocontrol, National Aviation Authorities)
are adopting new ATM concepts:
and tools, for example:
Over 95% of the total
Route charges revenues
Forecasted no. of IFR flights in CFMU area
Airports (number of take-off/landings)
Sectors (no. of flights entering the sector or no. of flights in the sector)
N.B.: Flight shift in time
N.B.: flight shift in space
Ground Holding Problem
MIN Total Cost of (ground + airborne delays)
A rerouting is sometimes imposed by CFMU.
Rerouting implies different route charges!
€ € €
where for each State i the charge is given by:
Distance traveled in State i
Unit rate in State i
Should better reflect actual ATC costs:
Innovative Route Charging Schemes

the final purpose of the Innovative Route Charging Schemes project is:

A congestion fee on a user is optimal when it is equal to the external costs that the user imposes on the other users.
For a M/G/1 queue:
Marginal Internal External
cost cost cost
Why not consider different categories and compute the “external” cost imposed within each category?

Deregulation and Liberalization drive a higher competition
Need to reduce costs
Need to enhance revenues
