RCO and DRCO (TP 2228E-19)

Safety Promotion & Education

RCO

Remote communications outlets (RCO) are remote radio transmitters/receivers established as an extended communications capability. They are used to

  • receive position reports;

  • retransmit ATC clearances; and

  • provide remote aerodrome advisory services (RAAS) or flight information services en route (FISE).

It should be noted that flight service stations (FSS) offering these services are not located on-site. RCO frequencies are used like any other frequency.

DRCO

A dial-up remote communications outlet (DRCO) is an RCO that is equipped with a commercial telephone line. The line is only "opened" once the pilot or flight service specialist has made a call, and only the flight service specialist can disconnect the line. DRCOs are used to provide FISE.

Activating the DRCO

  • Select the published RCO frequency;

  • Push the microphone button four times in no more than four seconds;

  • A dial tone will be heard;

  • The message "lien établi/link established" indicates that communication has been established;

  • Initiate the radio communication as usual.

Difficulties?

  • A "call terminated" message indicates that the telephone line has been inadvertently disconnected.

  • If the line is not available, a "try again" message will be broadcast.
