TCAS (traffic alert and collision avoidance system)
A type of airborne collision avoidance system (ACAS) based on a family of airborne equipment that functions independently of the ground-based ATC
system to detect potential conflicting aircraft that are equipped with secondary surveillance radar (SSR) transponders.
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.
MATS ACC > Glossary
safety alert
Notification by an air traffic controller to an aircraft that it is at an altitude that, in the controller’s judgment, places it in unsafe proximity to terrain, obstructions, or other aircraft
MATS ACC > Glossary
ACAS (airborne collision avoidance system)
An aircraft system based on secondary surveillance radar (SSR) transponder signals which operates independently of ground-based equipment to provide
advice to the pilot on potential conflicting aircraft that are equipped with SSR transponders
MATS ACC > Glossary
RA (resolution advisory)
An indication given to the flight crew by the airborne collision avoidance system (ACAS) or the traffic alert and collision avoidance system (TCAS) recommending
a manoeuvre or a manoeuvre restriction to avoid collision.

GPWS (Ground Proximity Warning System)
An aircraft system that is intended to provide warnings to the flight crew when flying in abnormal or dangerous situations close to the ground. The system also calls out the altitude during a landing.
MATS ACC > Glossary
