D-TAXI service for Controller-Pilot Data-Link Communications (CPDLC) application

Release: 2015

Reference: -

Location: Madrid

Description

This solution allows the use of data link communications between the tower controllers and the flight crew during surface movement, based on the D-TAXI service from the Controller-Pilot Data-Link Communications (CPDLC) application, already standardised by RTCA and EUROCAE. The service is accessed by end users, through the controller working positions and through the aircraft’s Datalink Control & Display Unit (DCDU)

Description of the exercises

A combination of live trials and simulations will validate both solutions (S22, S23). Real-time simulations in Paris will validate the relevance of alerts to tower controllers in case of conflicting ATC clearances, while a set of exercises in Madrid and Langen will assess the feasibility and benefits in terms of safety and performance of these solutions. A series of exercises at Riga International Airport will also assess the level of maturity for the integration of solutions addressing Airport Safety Nets and Integrated Surface Management.

Expected benefits

  • Increased efficiency
  • Improved predictability
  • Enhanced safety
