Define Radar Contact
|
-Pilots automatically discontinue reporting over compulsory reporting points |
|
Application
|
Before you provide radar service, establish and maintain radar identification of the aircraft involved |
|
Departure method
|
-Observe a departing aircraft within 1 mile of the takeoff runway end at airport with an operating control tower -Verbal or nonverbal rolling/ boundary notification |
|
Position Correlation Method
|
-Fixed must be displayed on the video map, scribed on the map overlay, or displayed as a permanent echo -Visual reporting points whose range and azimuth from the radar antenna has been accurately determined and made available to the controller Exception- If a TACAN/ VORTAC is located within 6,000 feet o the radar antenna, the TACAN/ VORTAC may be used as a reference fir for radar identification without being displayed on the video map or map overlay |
|
Turn Method
|
Observing a target make an identifying turn or turns of 30 degrees or more provided the following conditions are met: -Except in the case of a lost aircraft, a pilot position report is received which assures you that the aircraft is within radar coverage and within the area being displayed -Only one aircraft is observed making these turns |
|
Ident method
|
Request the aircraft to activate the "IDENT" feature of the transponder and then observe the identification display |
|
Code Change Method
|
Request the aircraft to change to a specific discrete or non discrete code, as appropriate, and the observe the target or code display change |
|
Squawk Standby/Squawk Normal
|
-Request the aircraft to change transponder to "standby" -After you observe the target disappear for sufficient scans, request the aircraft to return the transponder to normal operation and then observe the reappearance of the target |
|
Questionable Identification
|
-If identification is questionable for any reason, take immediate action to re-identify the aircraft or terminate radar service |
|
Inform an A/C of radar contact when
|
-Subsequent to loss of radar contact or terminating radar service, radar ID is reestablished |
|
Position information
|
-Inform the A/C of its position whenever radar ID is established by means of ID turns or by any of the beacon ID methods -Positions information need not be given when ID is established by position correlation or when a departing A/C is identified within 1 mile of the takeoff runway end |
|
Confirm aircraft ID
|
-A primary target by advising the aircraft of its position on the radar indicator -A beacon target by observing a code change, or an ident -A "standby" squawk unless one of these was used during handoff |
|
When using appropriate equipment consider a discrete beacon targets ID to be confirmed when
|
-You observe the deletion of a discrete code that was displayed in the data block -You observe the numeric display of a discrete code that an aircraft has been instructed to squawk or report squawking |
|
Issue Altimeter Setting
|
-If a pilot requests the altimeter setting in millibars, ask the nearest weather reporting station for the equivalent millibars setting NOTE: USAF/USA use the term "Estimated Altimeter" for altimeter settings reported or received as estimated |
|
Ensure Mode C altitude readouts are valid after accepting an interfaculty handoff, initial track start, track start from coast/suspend tabular list, missing or unreasonable Mode C readouts
|
-If altitude on scope varies less than 300 feet from the pilot reported altitude -You receive a continuous readout from the aircraft on the airport and the readout varies by less than 300 feet from the field elevation -You have correlated the altitude information in our data block with the validated information in a data block generated by another facility When unable to validate the readout do not use mode C altitude information for separation |
|
When you observe an invalid Mode C readout below FL 180
|
(LOCATION) ALTIMETER (NUMBER), VERIFY ALTITUDE |
|
If altitude readout continues to be invalid
|
STOP ALTITUDE SQUAWK, ALTITUDE DIFFERS BY (NUMBER OF FEET) |
|
When you observe an invalid Mode C readout at or above FL 180
|
CONFIRM USING TWO NINER NINER TWO AS YOUR ALTIMETER SETTING, VERIFY FLIGHT LEVEL |
|
if altitude readout continues to be invalid
|
-Instruct the pilot to turn off the altitude reporting part of his/her transponder and include the reason -Notify the operational supervisor-in charge of the aircraft call sign. STOP ALTITUDE SQUAWK, ALTITUDE DIFFERS BY (NUMBER OF FEET) |
|
Transponder
|
The airborne radar beacon receiver/transmitter portion of the ATC Radar beacon System (ATCRBS) which automatically receives radio signals from interrogators on the ground, and selectively replies with a specific reply pulse or pulse group |
|
Inoperative/Malfunction Transponder
|
ACID your transponder appears inoperative/malfunctioning, reset, squawk (beacon code) -If the aircrafts transponder is inoperative ensure the next control position is notified prior to the aircraft entering their airspace |
|
Inoperative or Malfunctioning Interrogator
|
Inform aircraft concerned when the ground interrogator appears to be inoperative or malfunctioning (Facility Name) beacon interrogator inoperative/malfunctioning |
|
Mode
|
-Make radar beacon code assignments to only Mode 3/A transponder-equipped aircraft -Unless specified in LOPs make code assigned, for radar beacon code environment in which you are providing ATC service -Give first preference to the use of discrete beacon code |
|
Code subset
|
-codes ending in 00 are non discrete -codes ending in other than 00 are discrete |
|
Function code
|
exception 1277 for SAR, 1255 FireFighter Computer Assigned code: -A beacon code assigned to a specific flight plan as a result of a program function or controller message input Terminal code: -Codes reserved for terminal use |
|
Beacon code changes for military aircraft
|
-Mental distractions and the inadvertent movement of aircraft controls resulting from the pilots turning, reaching, or leaning to change frequencies can induce spatial disorientation (vertigo) |
|
Beacon code changes to military aircraft
|
-Avoid radio frequency and radar beacon changes to the maximum extent that communications capability and traffic will permit -Keep frequencies/radar beacon changes to a minimum below 2,500 feet above the surface -Give instructions early enough to allow the change before the aircraft reaches the approach fix or handoff point -Avoid changes while the aircraft is making a turn -Avoid making frequencies and radar beacon codes changes after an aircraft begins a high altitude approach |
|
Emergency code assignment
|
-After radio and radar contact have been established, you may request other than single piloted helicopters and single-piloted turbojet aircraft to change from code 7700 to another code -The code change, based on pilot concurrence, the nature of the emergency, and current flight conditions will signify to other radar facilities that the aircraft in distress is identified and under ATC |
|
Radio failure code
|
VFR code assignments -Assign an appropriate function code or computer assigned code for VFR aircraft receiving radar advisories -Instruct IFR aircraft which cancel an IFR flight plan and are not requesting radar advisory service and VFR aircraft for which radar advisory service is being terminated to squawk VFR |
|
Failure to display assigned code/inoperative transponder
|
-Inform an aircraft with an operative transponder that the assigned beacon code is not being displayed ADIC reset transponder, squawk code -Inform an aircraft when its transponder appears to be inoperative or malfunctioning ADIC your transponder appears inoperative, reset, squawk code -Ensure subsequent control positions are notified of an aircraft transponder malfunctions |
|
Control Radar Departures
|
-Avoid using the term takeoff except to actually clear an aircraft for takeoff or to cancel a takeoff clearance -Use such terms as depart, departure or fly in clearance when necessary -Do not release an aircraft if a ground stop, applicable to that aircraft is in effect, without the approval of the originator of the GS |
|
Radar departure procedures
|
-Do not assign these route solely to provide for possible radar or communication failure |
|
Control Radar departures
|
-The ring line will be used to obtain IFR releases. This function may be completed through the CI/CT line when those positions are manned. Releases are valid for 5 minutes after issue Rapcon Shall: -Advise tower of estimated delay when issuing aircraft hold for release -Have control of aircraft for early turns up to 90 degrees left or right of centerline prior to the aircraft reaching 2900 MSL before exiting class D airspace. An aircraft must cross departure end of the runway prior to initiating the turn. Tower may cancel early turn outs as needed -Assume control for turns greater than 90 degrees for aircraft leaving 2900 MSL assigned an altitude at or above 4000 MSL Tower Shall: -Request approval for IFR aircraft that request to depart VFR (VFR release of IFR aircraft) -Provide departure roll calls for IFR departures VIA the shout line -Issue heading/restrictions verbatim. |
|
VFR release of an IFR aircraft
|
-Inform the pilot of the proper frequency and where or when to contact the IFR facility -If the facility/sector responsible for issuing the clearance is unable to issue a clearance, inform the pilot, and suggest that the delay be taken on the ground -If the pilot insists upon taking off VFR and obtaining an IFR clearance in the air, inform the facility/sector holding the flight plan of the pilots intentions and, if possible, the VFR departure time. |
|
VFR departure phraseology
|
VFR DEPARTURE AUTHORIZED. CONTACT (facility) ON (frequency) AT (location or time if required) FOR CLEARANCE. |
|
Satellite airport departure phraseology
