Abstract

Controller–pilot data link communications (CPDLC) is used for reducing the voice network congestion by providing a data link communication system to the pilots and air traffic controllers (ATC). The CPDLC system achieve its objective, but the system requires the Pilot/ATC to input using appropriate codes as approved/recommended by International Civil Aviation Organization (ICAO) having multiple process steps which entails significant time and effort. The entire process considerably increases the aircraft crew workload and heads down time, which adds to pilot fatigue and distraction while operating the aircraft. Proposed invention enables the system to reuse older messages made available as “canned message(s)” or a database of such “canned message(s)” to be made handy to the crew. The proposed invention will reduce the work load by eliminating the need for remembering/referring the previous downlink while composing a message to resend it. Proposed invention is equally applicable for controller and will improve their efficiency.

1.            Introduction

Controller–pilot data link communications (CPDLC), also referred to as controller pilot data link (CPDL), is a method by which ATC can communicate with pilots over a datalink system. The datalink system services provide for exchange of communication management and clearance/information/request messages in standard ATC message format over a network. The CPDLC message set is contained in ICAO Doc 4444: PANS-ATM, Annex 5. The ICAO provisions: Annex 10 Volume Part 1 Chapter 3 details the communication procedure. There is also a “free text” capability provided to exchange information not confirming to defined format to cover for non standard requests and commands.

The CPDLC is two-way communication between the ground controller and pilot with the messages to be acknowledged or accepted appropriately by each party. Since each message has to be entered appropriately using the standard message format at most of the instances, there is a lot of time and effort from Pilot and Ground Controller to communicate using CPDLC. This necessitates the CPDLC communication to be used only in non-time-critical situations. CPDLC reduces congestion on ATC voice link, allows for concise and accurate information exchange, and reduces in-flight communication errors. In current CPDLC systems, the method for communicating a data link message comprises transmitting a data link message from a sender to a receiver and storing the transmitted data link message. Pilots will have to navigate to specific pages and then key in various data to be able to send a downlink to the ground. If the pilots want to modify a rejected/expired/aborted message, they have to remember what the previous message stated, or have a print out copy of the previous message, and then manuall...
