Time-Based Operations


All market research and development within digital Air Traffic Management points to that accurate information of atmospheric conditions is imperative for Time-based Operations (TBO). TBO is the first step of the major European SESAR project as well as the US NextGen initiative, aimed at modernizing the European and US air transport systems to gain a much needed increase in airspace and airport capacity, as well as, amongst others, increased safety. TBO involves the ability to, at all times, be able to accurately predict where an aircraft will be positioned during a flight, and within seconds when it is to land. To achieve those objectives one need to consider actual individual aircraft performance as well as the current meteorological conditions flown. That information furthermore needs to be integrated in the control systems of airports and air navigation service providers in order for the air transport system as a whole to be optimized.

Differently put TBO increases the capacity and efficiency of the air transport system by significantly reducing variation and waste. Variation and waste are both results of lack of specific data for automation and human operators and AVTECH has the capability to reduce variation and waste through innovative use of data (meteorological, FMS, ADS-B, etc.) in modular systems utilizing an airborne perspective.

AVTECH has over a number of years, as one of only a few companies in the world, developed a number of solutions who fit within the general framework of Time-based Operations and who utilize the existing technologies within aviation to guarantee successful near-term implementation. The Aventus NowCast solution is the company’s first commercial service within Time-based Operations and AVTECH is currently undertaking continued developments and investment activities to futureproof and expand the company’s range of technical capabilities within TBO. The modular structure of AVTECH’s technical core makes it relatively easy to combine and integrate different capabilities to achieve the required output, whether it relates to Aventus NowCast, to solutions oriented towards time-based flow management, or towards solutions aimed at addressing Wake Vortex issues at congested airports.
