are in radar contact:  Subsequent to being advised that the controller has  established radar contact, this fact is not repeated to  the pilot when handed off to another controller. At  times, the aircraft identity is confirmed by the receiving  controller; however, this should not be construed to  mean that radar contact has been lost. The identity of  transponder equipped aircraft is confirmed by asking  the pilot to “ident,” “squawk standby,” or to change  codes. Aircraft without transponders are advised of  their position to confirm identity. In this case, the pilot  is expected to advise the controller if in disagreement  with the position given. Any pilot who cannot confirm  the accuracy of the position given because of not being  tuned to the NAVAID referenced by the controller  should ask for another radar position relative to the  tuned in NAVAID.  Position reports should include the following items: The following reports should be made at all times to  ATC or Flight Service facilities without a specific ATC  request:  When informed by ATC that their aircraft are in “Radar  Contact,” pilots should discontinue position reports over  designated reporting points. They should resume normal  position reporting when ATC advises “radar contact lost”  or “radar service terminated.” ATC informs pilots that they  In addition to acknowledging a handoff to another Center  en route controller, there are reports that should be made  without a specific request from ATC. Certain reports should  be made at all times regardless of whether a flight is in radar  contact with ATC, while others are necessary only if radar  contact has been lost or terminated. [Figure 2-68]  If radar contact has been lost or radar service terminated,  the CFRs require pilots to provide ATC with position reports  over designated VORs and intersections along their route  of flight. These compulsory reporting points are depicted  on IFR en route charts by solid triangles. Position reports  over fixes indicated by open triangles are noncompulsory  reporting points and are only necessary when requested by  ATC. If on a direct course that is not on an established airway,  report over the fixes used in the flight plan that define  the route, since they automatically become compulsory  reporting points. Compulsory reporting points also apply  when conducting an IFR flight in accordance with a VFR- on-top clearance.  Whether a route is on an airway or direct, position reports  are mandatory in a non-radar environment, and they  must include specific information. A typical position  report includes information pertaining to aircraft position,  expected route, and ETA. When a position report is to be  made passing a VOR radio facility, the time reported should  be the time at which the first complete reversal of the TO/  FROM indicator is accomplished. When a position report is  made passing a facility by means of an airborne ADF, the  time reported should be the time at which the indicator  makes a complete reversal. When an aural or a light panel  indication is used to determine the time passing a reporting  point, such as a fan marker, Z marker, cone of silence or  intersection of range courses, the time should be noted  when the signal is first received and again when it ceases.  The mean of these two times should then be taken as the  actual time over the fix. If a position is given with respect to  distance and direction from a reporting point, the distance  and direction should be computed as accurately as possible.  Except for terminal area transition purposes, position  reports or navigation with reference to aids not established  for use in the structure in which flight is being conducted  are not normally required by ATC.  2-46  Flights in a Radar Environment  Additional Reports  Position Report Items Non-Radar Position Reports  En Route Reporting Procedures  1.
