“RDOF” blinks in the data block
Issue code ____ to VFR aircraft when:
1200
- IFR aircraft cancels IFR flight plan and does not request radar advisories
- Radar services are being terminated
The radar team shall continuously monitor __________________________ assigned for use by aircraft within your area of responsibility, including:
Mode 3/A radar beacon codes

- Code 1202 - Glider operations
- Code 1255 - Firefighting aircraft
- Code 1277 - Search and Rescue aircraft
- Code 4000 - Fast maneuvering military aircraft
When using only Mode 3/A radar beacon to identify a target, use one of the following methods:
- Request aircraft to ident and observe the display
- Request the pilot to change to a specific discrete or nondiscrete code, as appropriate, and then observe the target or code display change.
- Request the pilot to change their transponder/ ADS−B to “standby.” After you observe the target disappear for sufficient scans to assure that loss of target resulted from placing the transponder/ADS−B in “standby” position, request the pilot to return the transponder to normal operation and then observe the reappearance of the target.
Identify a primary target by one of the following methods:
- Observing a target whose position with respect to a fix or a visual representation corresponds with a direct position report from the aircraft
- Observing a target making an identifying turn of 30 degrees or more, provided that the aircraft is in your airspace and above the MIA in your area
Phraseology to inform an aircraft that it is radar contact
“RADAR CONTACT (position, if required).”
Inform an aircraft when radar service is terminated because:
- Identification is no longer necessary
- Aircraft proceeds into nonradar coverage area
Radar service is automatically terminated and the aircraft need not be advised of termination when:
- An aircraft cancels its IFR flight plan, except:
- Within Class B airspace
- Within Class C airspace
- Where basic radar service is provided
- An aircraft conducting an instrument, visual, or contact approach has either:
- Landed, or
- Been instructed to change to advisory frequency
An arriving aircraft shall be informed when radar service is terminated at tower-controlled airports where ____.

The three types of track are:
- Free Track
- Flight Plan Aided Tracking (FLAT) Track
- Coast Track
Free Track
- Position symbol - ∆
- Utilizes latest ground speed and heading information
- Displayed with data block on display
- Oriented relative to initial direction of track based on radar data
Flight Plan Aided Tracking (FLAT) Track
Flight Plan Aided Tracking (FLAT) Track
- Position symbol - ◊
- Utilizes Free Track process plus information from the flight plan
- Based on:
− Airway or route heading in the flight plan
− Speed
→ Filed True Airspeed (TAS) determines ground speed prediction
→ Forecast upper winds are taken into consideration
− Planned maneuvers
→ Prediction is based on planned route changes
A physical or automated action taken by a controller to transfer the radar identification of an aircraft to another controller if the aircraft will or may enter the airspace or protected airspace of another controller and radio communications will not be transferred.
