Question 4

Define Non-ATS Operating Irregularity

Answer 4

Terminav

NON-ATS OPERATING IRREGULARITY - A situation that occurs when ATS are being provided and when a preliminary investigation indicates that a hazardous situation or loss of separation may have occurred and that ATS have not contributed to the situation.

Question 5

Define Occurrence

Answer 5

MATS ACC > Glossary

OCCURRENCE - Any event that is irregular, unplanned, or non-routine in nature, including any accident, incident, or other occurrence that involves aircraft, NAV CANADA employees, or facilities or any ATS system deficiency

Question 7

Define TCAS

Answer 7

MATS ACC > Glossary

TRAFFIC ALERT AND COLLISION AVOIDANCE SYSTEM (TCAS) - 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.

Question 8

Define Safety Alert

Answer 8

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

Question 9

Define ACAS

Answer 9

MATS ACC > Glossary

AIRBORNE COLLISION AVOIDANCE SYSTEM (ACAS) – 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

Question 10

Define RA

Answer 10

MATS ACC > Glossary

RESOLUTION ADVISORY (RA) - 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.

Question 11

Define GPWS

Answer 11

MATS ACC > Glossary

GROUND PROXIMITY WARNING SYSTEM (GPWS) - 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.

Question 12

Define TAWS

Answer 12

MATS ACC > Glossary

TERRAIN AWARENESS AND WARNING SYSTEM (TAWS) - An aircraft system that is intended to provide a flight crew with both aural and visual alerts to aid in preventing controlled flight into terrain, obstacles, or water.

Question 13

Define PIREP

Answer 13

MATS ACC > Glossary

Question 14

Define Urgent PIREP

Answer 14

MATS ACC > Glossary

URGENT PIREP - A pilot report containing weather information significant to the safety of flight. An urgent PIREP includes information on any of the following:
* Volcanic ash
* Tornadoes, funnel clouds, waterspouts
* Severe turbulence
* Severe icing
* Hail
* Low-level wind shear
* Any other reported weather phenomena considered to be hazardous or potentially hazardous to flight operations

Question 15

Define AIRMET

Answer 15

MATS ACC > Glossary

AIRMET - Information message issued by a meteorological watch office (MWO) to advise pilots of the occurrence or expected occurrence of specified weather phenomena which may affect the safety of aircraft operations and were not already included in a Graphic Area Forecast (GFA), and the development of those phenomena in time and space.

Question 16

Define Chaff Burst

Answer 16

Terminav

CHAFF BURST - An expression used in radio communication to inform ATC of chaff drops at intervals short enough to appear on radar displays as an individual target.

Question 17

Define MEDEVAC

Answer 17

MATS ACC > Glossary

MEDEVAC - A term used to request Air Traffic Service priority handling for a medical evacuation flight, based on a medical emergency in the transport of patients, organ donors, organs, or other urgently needed life-saving medical material. The term is used on flight plans and in radiotelephony communications if a pilot determines that a priority is required.
