To assess the punctuality performance of air navigation at airports, only arrivals are considered. The timely departure of an aircraft depends on many other factors – such as ground services (baggage, refueling etc.) – which do not depend on skeyes, but which are coordinated with skeyes based on the concept of the Airport CDM (Collaborative Decision Making) through an information exchange application – the AMS (Airport Movement System) – developed by skeyes. Reducing arrival delays at airports is an important performance indicator for airlines, the attractiveness of the airport and reducing the environmental impact. This performance has a positive impact on activity and employment while preserving the environment as much as possible. It is therefore an important lever for the sustainable development of aviation.
Brussels Airport: punctuality that attracts
Through its performance in terms of arrival punctuality at Brussels Airport, skeyes contributes directly to the attractiveness of the national airport, its development and that of the Belgian economy, as well as to reducing the impact on the environment, greenhouse gas emissions and pollutants.
