Earlier research has explored the potential of aircraft-based route conformance monitoring for airport navigation. In this research, the routeconformance monitoring function was hosted on an experimental Electronic Flight Bag (EFB) and evaluated in a simulated operation. A datalink was used to load the route from Air Traffic Control (ATC). The current research addresses the design, integration and evaluation of a manual input option and the comparison with a previously developed voice input option. Results suggest that with the manual input option it is possible to enter the route during its reception (i.e. instructions from ATC via R/T) and perform the readback based on the data presented on the EFB. This way, the integrity of the route used by the conformance-monitoring function is assessed by ATC.
4-Dimensional (4D) Trajectory-Based Operations (TBO) are viewed as a key enabler for future air operations by both SESAR 1 and NextGen 2 . The European Commission project NUP 2+ 3 has created a unique infrastructure that provides the networking of real-time 4D Trajectory (4DT
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
