Fichas del conjunto (15)
- 1Surveillance. ConsistIt consists of determining the position (lateral and vertical) of any vehicle or object within a given airspace sector.
- 2Initial Surveillance Methods1) Observation: in the vicinity of aerdromes. Still done ATCO.
2) Noise detection: enemy incursions. Now, measure noise levels (environmental effect).
3) Radio report: pilot sends information to ATCO (Position, FL,time..). Named procedural Control. - 3Radar stands for...Radio Dectection and Ranging
- 4What does a radar consist of?High frequency radio transmitter broadcasting high energy short-length radio waves through a rotating antenna. A small proportion of the energy will be reflected by the surface of the aircraft travelling back to the radar receiver.
- 5PSR stands for...Primary Surveillance Radar
- 6Explain PSRsUsed to detect objects, sends radio signals for given azimuth angles and for all elevation
angles, being thus unable to detect the altitude of the targets - 7PSR drawbacks- Amount of energy that needs to be radiated. - Difficult correlation
- Unable to detect altitudes - Echo easily fading away - Limit coverage - They also receive information of stationay objects, filters are compulsory. - 8List the different types of radar used in aviation- PSR: Primary Surveillance Radar
- SSR Secondary Surveillance Radar
- WXR: Weather Radar
- RA: Radio altimeter - 9SSR stands forSecondary Surveillance Radar
- 10Which Surveillance Radar needs collaboration from the transponder otherwise it does not work?SSR
- 11SSR Transponder Modes- Alpha Mode: solves correlation
- Charlie Mode: also solves altitude.
- Sierra Mode: IAS, Magnetic Heading, Mach number, altitude - 12Alpha Mode. ExplainTransponder sends back a code of four number in octals {0,7} selected by the pilot in the cockpit. ATCO assign a single transponder code to each flight plan. Codes are displayed on the radar screen identifying the aircraft.
- 13Charlie Mode. ExplainThe transponder sends pressure values retrieved from static ports to the SSR antenna. Altitude information together with callsign is displayed on screen. They take into account local QNH and relative position of aircraft with respecto to TA and TL, not depending to the Kollsman window selection of the pilot
- 14SACTA stands for... Developed by..Sistema para la Automatización del Control de Tránsito Aéreo.
Developed by Indra - 15—
