Are you certain you are billing for all flights in your airspace? Are too many air operators rejecting your invoices because of inaccuracies caused by manual data gathering processes? And what if you could free yourself from the hassle of pursuing operators for payments? As a part of any air navigation service providers, airline operator or airport authority, kindly ask above question to your own. Here I know aeronautical or air navigation billing has various kind of charges. For e.g. Air navigation charges for landing and en-route flight movements, airport passenger service charges, passenger safety charges, cargo safety charges, safety scheme of charges and many more related to airport authorities. Majority of authorities process monthly invoice batch processing for above charges with even one month additional credit towards operators. Manual process of data capturing, calculating, invoicing for above charges need heavy main power and validation and verification process even become complex and time consuming which lead to inaccuracies in data and revenue.
