Radar Identification Flashcards
What must you do before you provide radar service?
Establish and maintain radar identification
What methods of radar identification do you use when using only Mode 3/A?
- Request aircraft to ident and observe the display
- Request aircraft to change to a computer assigned code and observe the display (assigned code should be in the limited data block)
- Observe automatic track acquisition of aircraft squawking a discrete computer assigned beacon code (full data block appears with associated target)
How do you identify a primary target?
- Observing a target whose position with respect to a fix or visual representation corresponds with a direct position report from the aircraft (fix must be displayed on the map overlay, the observed track is consistent with the reported heading for route of flight)
- Observing a target making an identifying turn of 30 degrees or more provided the aircraft is in your airspace and above the MIA in your airspace before issuing the heading
When do you inform an aircraft that it is in radar contact?
When initial radar identification in the ATC system is established and when radar contact is reestablished
When do you inform an aircraft that radar contact is lost?
When identification is still desired but lost due to some
uncontrollable situation like radar failure or no target return
What do you do if identification is questionable for any reason?
- Take immediate action to re identify the aircraft or terminate radar service
- Ensure all primary targets are displayed when radar identification is lost or questionable
When must you inform an aircraft of its position when radar identifying them?
Beacon methods or turns
When is position information not needed to be given when radar identifying an aircraft?
Position correlation
Inform an aircraft when radar service is terminated because of:
Identification is no longer necessary or aircraft proceeds into nonradar coverage area
When is radar service automatically terminated and the aircraft need not be advised?
• An aircraft cancels its IFR flight plan except in class B or C airspace and where basic radar service is provided • An aircraft conducting an instrument, visual, or contact approach has either landed or been instructed to chance to advisory frequency
When must and arriving aircraft be informed then radar service is terminated at tower-controlled airports?
Where radar coverage does not exist within ½ miles of the end of the runway
When will an aircraft discontinue and resume reporting over compulsory reporting points?
Discontinue when radar identified and resume when ATC
advises radar contact lost or radar service terminated
To provide continuous identity, use data blocks that are associated with the appropriate target symbol and retain the data block until….?
The aircraft has exited the sector or delegated airspace and all potential conflicts have bee resolved (this includes point out aircraft)
What items are required to be displayed in the full data block?
ACID, interim or assigned altitude or reported altitude
What must be displayed when you have responsibility for an aircraft and a paired track exists?
