MATS ACC > Appendix Professional Standards > Functional Goal #1
In the provision of air traffic control and flight information service, all Air Traffic Services units must provide:
- Uniform application of approved standards and procedures
- Professional communications
- Full–time attentive flight monitoring and flight information services
MATS ACC > Appendix: Communication > Communication Fundamentals
Restrict communications to air traffic services messages. In all radio, interphone, SATVOICE, and telephone communications, use:
- Proper phraseology
- Phonetic alphabet and numbers, as necessary
- Correct procedures for transmitting numbers.
Most losses of separation occur when:
- pilots do not comply with clearances or instructions;
- controllers issue clearances that place aircraft into conflict;
- controllers do not act to eliminate a conflict.
MATS ACC > Glossary
TCAS (traffic alert and collision avoidance system)
There are three different versions:
- TCAS I provides traffic advisories.
- TCAS II provides traffic advisories and vertical resolution advisories (RA)
- TCAS IV, when developed, will provide traffic advisories and vertical and horizontal RAs.
ACC > Emergencies and Urgent Operations > Traffic, Low Altitude, and Airspace Alerts > Traffic
If an aircraft is in unsafe proximity to another aircraft…
… issue a traffic alert.
CC > Emergencies and Urgent Operations > Traffic, Low Altitude, and Airspace Alerts > Traffic
Upon display of a valid conflict alert advisory or in response to a loss or imminent loss of separation between identified aircraft in controlled airspace…
issue a traffic alert and avoidance instructions including the word IMMEDIATELY

Altitude where conflict avoidance software has been implemented?
14 000 and above
_______________ _____________required to determine what constitutes an imminent loss of separation below 14000 feet, where conflict alert software has not been implemented.
Controller judgment

If an aircraft is at an altitude that is in unsafe proximity to terrain or an obstruction, …
issue a low altitude alert
MATS ACC > Emergencies and Urgent Operations > Traffic, LowAltitude, and Airspace Alerts > ACAS/TCAS and GPWS/TAWS
If you become aware that an aircraft has deviated from an ATC clearance or instruction as a result of an ACAS/TCAS RA or GPWS/TAWS warning manoeuvre…
… inform your supervisor
MATS ACC > Emergencies and Urgent Operations > Traffic, Low Altitude, and Airspace Alerts > ACAS/TCAS and GPWS/TAWS
If a pilot advises that they are responding to an ACAS/TCAS RA or GPWS/TAWS warning:
- Do not attempt to modify the aircraft flight path until the pilot reports returning to the terms of the current ATC clearance or instruction.
- Provide relevant traffic and collision avoidance information, as appropriate.
MATS ACC > Emergencies and Urgent Operations > Traffic, Low Altitude, and Airspace Alerts > ACAS/TCAS and GPWS/TAWS
Resume responsibility for separation after an aircraft has responded to an ACAS/TCAS RA or GPWS/TAWS warning when both of the following have occurred:
- The pilot informs you of any of the following:
◦ The manoeuvre is complete.
◦ The aircraft has returned to its assigned altitude.
◦ The aircraft is following an alternate clearance. - You have verified that separation exists.
