Lesson 21 Flashcards
What are the five key rules for ATS personnel when it comes to equipment?
- Test All Equipment
- Do Not Tamper with Equipment
- Display Irregular Operating Status Information
- Report Malfunction
- Do Not Use Malfunctioning Equipment
Describe RADAR
Radar (RAdio Detection And Ranging) is a detection system that uses radio waves as an electronic form of echolocation to determine the position of objects.
Describe PSR
Primary surveillance radar (PSR) systems rely on reflected radio waves.
Describe SSR
secondary surveillance radar (SSR) systems use an interrogation-reply system.
The radar system broadcasts a request for information (interrogation) and a transponder on
board each individual aircraft replies with encoded data such as its identity and altitude.
Describe RSE
Radar site equipment (RSE) refers to the housing that contains radar and electronic equipment
necessary for detecting aircraft.
Describe Terminal Surveillance Radar
Located at major Canadian airports, terminal surveillance radar (TSR) consists of co-located PSR and SSR antennae
Independent Secondary Surveillance Radar
independent secondary surveillance radar
(ISSR) provides accurate range and azimuth positioning for aircraft equipped with transponders.
Describe Multilateration
Multilateration (MLAT) is a surveillance technology that uses the measured differences in the times of arrival (TOAs) of energy waves. (like a SSR)
Describe Surface Movement Guidance and Control System
At larger airports, Surface Movement Guidance and Control System (SMGCS) is used to
provide tower controllers with highly accurate position information on aircraft and vehicles
operating on the surface of the airport. It uses similar principles as PSR. Think of SMGCS as
primary radar located at the top of a control tower and pointed at the ground.
Describe ADS-B
Automatic dependent surveillance-broadcast (ADS-B) is a surveillance technology that allows
an appropriately equipped and certified aircraft to determine its position via satellite navigation
and periodically broadcast that information for surveillance purposes. ADS-B can be ground- or
space-based.
describe VSCS
Voice Switch Communications System (VSCS) is the primary communication technology used in ATS.
Describe ATIS
automatic terminal information service (ATIS)
It is used to notify arriving and departing aircraft of important data such as:
* Current surface weather
* Active runways
* Runway and taxiway conditions
* Communications frequencies
What is EXCDS?
Extended Computer Display System (EXCDS) is a flight plan manipulation and display system
What is NARDS?
NAV CANADA Auxiliary Radar Display System (NARDS) is used for displaying and
manipulating surveillance targets and flight plans.
Describe CVIDS
Computerized Video Information Display System (CVIDS) contains graphics files that show useful operational information, such as approach plates and local emergency procedures.
