(1) ATM - PSR Identification Flashcards
What is Identification? (1)
The situation which exists when the position indication of a particular aircraft is seen on a situation display and is positively identified (ICAO)
What is a Radar Map? (1)
Information superimposed on a situation display to provide ready identification of selected features
What is video Mapping? (1)
The electronic superimposing of a map or plan on a situation display
what are the 3 types of PSR identification methods? (3)
- The Turn Method
- Departing Aircraft Method
- Position Report Method
What is the Turn method? (3)
- Ascertain the aircraft’s heading
- Observe the aircraft’s track for a period of time
- Correlate the observed movement of a particular Position Indication with an acknowledged execution of an instruction to alter heading by at least 30 degrees

What should an ATCO consider before instructing an aircraft to turn for ID purposes? (5)
- Terrain
- PSR coverage
- Other surveillance returns
- Rules of the Air
- Proximity of Controlled airspace boundary
Turn method Caution diagram
What is the Departing aircraft method? (2)
- Identification is achieved by observing and correlating the Position Indication of a departing aircraft to a known airborne time
- Identification is to be achieved within 1nm of the end of the runway used
What cautions should an ATCO consider with the departing aircraft method? (4)
- Aircraft overflying the airfield
- Aircraft making a Missed Approach
- Aircraft departing from an adjacent runway
- Aircraft holding overhead the airfield
What is the Position reporting method? (4)
- Correlate a particular radar position indication with an aircraft reporting its position over, or as bearing and distance
- Ascertaining that the track of the particular radar position is consistent with the aircraft path or reported heading
- Can be achieved by correlating a particular Position Indication with a report from the aircraft over one of two defined types of position or navigational fix
- Identification must follow a period of track observation in which the Position Indication correlates with the pilot’s reported route
What is meant by the term “a point”? (2)
- A geographical point suitable for the purposes of identification
- Normally defined by reference to a radio Nav aid or aids
What 2 types can be a point of reference for a position report? (2)
- Exact reporting point
- VRP or other geographical location
Position reporting method 1 - part 1 diagram
A position established by a navigational facility, which is:
- Overhead a VOR or NDB
- A notified fix defined by VOR radials or a VOR radial and a bearing from an NDB
- A position defined by a VOR radial and a range from a co-located DM
Position reporting method 1 - part 2 diagram
At a particular distance and on a particular radial from a co-located VOR/DME or TACAN
Position reporting method 2 diagram
- Over a notified visual reference point or prominent geographical feature, in either case approved for the purpose and displayed on the situation display
- ATS authority may prescribe additional conditions
What cautions should an ATCO consider with the position reporting method? (2)
- Use an alternative method if there is any doubt concerning the identification
- The appropriate ATS authority may prescribe conditions for the application of these methods
How can mis-identification happen? (4)
- Incorrect assumptions concerning identity
- Identification procedures not correctly applied
- Turn Method - two aircraft make co-incident turns
- Pilot makes inaccurate position report which coincides with position of another aircraft
How may an ATCO act upon mis-identification? (5)
- Instruct to resume own navigation
- Climb aircraft to safe level if necessary
- Provide vertical separation from other aircraft and pass essential traffic information
- Continue to search for aircraft (Use equipment aids)
- Cancel any descent clearance and advise pilot to climb back to original level
A pilot shall be advised whenever identification is lost. True or False?
True
