COM 4.6 DIRECT CONTROLLER – PILOT COMMUNICATIONS

As data link becomes an important means of delivering ATS, there are crucial questions that shall be answered before this technology is used for safety-critical communications. This need is especially true where a data link communications system is the primary, or even integral, element in allowing the reduction of separation minima.


IFATCA Policy is:

In any ATS system where data link is considered safety-critical, data link shall be accompanied by direct two-way controller-pilot voice communications. This direct voice functionality shall be rapid, continuous, and static free.

Direct voice communications requires that no third human party is involved in the set-up and / or delivery of these communications. Any set-up procedures by either pilot or controller shall be minimal and nearly instantaneous.

For datalink communications to be considered direct controller-pilot communications, they shall support communications equivalent to the VHF in terms of transaction times and HMI.
