Static Information

ALDIS maintains data in ICAO, IATA, and UK CAA formats to facilitate accurate billing of aircraft. This information is stored in an underlying database that can be accessed by both AFIDS and ALDIS. The data includes information on airports, aircraft standards, names and addresses, operator aircraft, and operators, as well as operator-specific invoice periods.

Billing Engine

Flexibility and configurability are at the core of the ALDIS billing engine. This allows users to input and the software to calculate standard rates, flat rates, operator charges, and more. These calculations are based on information from the database and the airport's fees and charges.
ALDIS can calculate and credit a wide range of configurable charges, including landing and parking fees, fuel, passenger tax, services provided to an aircraft such as de-icing fluid, ground power usage, crew transport, and miscellaneous fees related to a movement.
