Computer Input-Output Technologies that Link Pilots and Air
Traffic Controllers
Both the Federal Aviation Administration (FAA) and
Eurocontrol (Europe’s FAA) actively research, experiment with,
and deploy technologies in order to create a safer and more
efficient airspace system.
An example is Controller-Pilot Data Link Communications
(CPDLC), which in addition to the existing radio, creates a
second channel for communication between pilots and air traffic
controllers (ATC). Instead of keying the radio, ATC and pilots
type instructions and requests and send via text messaging. This
reduces ATC workload and frees up the radio channels for
important communications.

Case Study Questions:
What computer technologies do you recognize being used in the
videos? What benefits are derived from the application of
computer technology to controller – pilot communications?
What are the challenges or risks of using CPDLC?
Your case study outline draft is due before the end of this
module. Your instructor will review your work and provide
feedback.
