Pilot/Controller Glossary Pilot/Controller Glossary  8/15/19 12/31/20  COMPULSORY REPORTING POINTS- Reporting  points which must be reported to ATC. They are  designated on aeronautical charts by solid triangles or  filed in a flight plan as fixes selected to define direct  routes. These points are geographical locations  which are defined by navigation aids/fixes. Pilots  should discontinue position reporting over compul- sory reporting points when informed by ATC that  their aircraft is in “radar contact.”  COMMON ROUTE- Typically the portion of a  RNAV STAR between the en route transition end  point and the runway transition start point; however,  the common route may only consist of a single point  that joins the en route and runway transitions.  COMMON TRAFFIC ADVISORY FREQUENCY  (CTAF)- A frequency designed for the purpose of  carrying out airport advisory practices while  operating to or from an airport without an operating  control tower. The CTAF may be a UNICOM,  Multicom, FSS, or tower frequency and is identified  in appropriate aeronautical publications.  COMPUTER NAVIGATION FIX (CNF)- A  Computer Navigation Fix is a point defined by a  latitude/longitude coordinate and is required to  support Performance-Based Navigation (PBN)  operations. A five-letter identifier denoting a CNF  can be found next to an “x" on en route charts and on  some approach charts. Eventually, all CNFs will be  labeled and begin with the letters “CF" followed by  three consonants (e.g., ‘CFWBG'). CNFs are not  recognized by ATC, are not contained in ATC fix or  automation databases, and are not used for ATC  purposes. Pilots should not use CNFs for point-to- point navigation (e.g., proceed direct), filing a flight  plan, or in aircraft/ATC communications. Use of  CNFs has not been adopted or recognized by the  International Civil Aviation Organization (ICAO).  I  (See DESIGNATED COMMON TRAFFIC  ADVISORY FREQUENCY (CTAF) AREA.)  (Refer to AC 90-66, Non-Towered Airport Flight  Operations.)  COMPASS LOCATOR- A low power, low or  medium frequency (L/MF) radio beacon installed at  the site of the outer or middle marker of an instrument  landing system (ILS). It can be used for navigation at  distances of approximately 15 miles or as authorized  in the approach procedure.  a.  Outer Compass Locator (LOM)- A compass  locator installed at the site of the outer marker of an  instrument landing system.  (See OUTER MARKER.)  b.  Middle Compass Locator (LMM)- A compass  locator installed at the site of the middle marker of an  instrument landing system.  (See MIDDLE MARKER.)  (See ICAO term LOCATOR.)  (REFER to AIM 1-1-17b5(i)(2), Global  Positioning System (GPS).  CONDITIONS NOT MONITORED- When an  airport operator cannot monitor the condition of the  movement area or airfield surface area, this  information is issued as a NOTAM. Usually  necessitated due to staffing, operating hours or other  mitigating factors associated with airport operations.  CONFIDENCE MANEUVER- A confidence man- euver consists of one or more turns, a climb or  descent, or other maneuver to determine if the pilot  in command (PIC) is able to receive and comply with  ATC instructions.  COMPASS ROSE- A circle, graduated in degrees,  printed on some charts or marked on the ground at an  airport. It is used as a reference to either true or  magnetic direction .  COMPLY WITH RESTRICTIONS - An ATC  instruction that requires an aircraft being vectored  back onto an arrival or departure procedure to comply  with all altitude and/or speed restrictions depicted on  the procedure. This term may be used in lieu of  repeating each remaining restriction that appears on  the procedure.  CONFLICT ALERT- A function of certain air traffic  control automated systems designed to alert radar  controllers to existing or pending situations between  tracked targets (known IFR or VFR aircraft) that  require his/her immediate attention/action.  (See MODE C INTRUDER ALERT.)  CONFLICT RESOLUTION- The resolution of  potential conflictions between aircraft that are radar  identified and in communication with ATC by  ensuring that radar targets do not touch. Pertinent  COMPOSITE FLIGHT PLAN- A flight plan which  specifies VFR operation for one portion of flight and  IFR for another portion. It is used primarily in  military operations.  (Refer to AIM.)
