• Departing the IAF, stating the approach that is being  initiated.  • Procedure turn (or equivalent) inbound.  • FAF inbound, stating intended landing runway and  maneuvering direction if circling.  • Short final, giving traffic on the surface notification  of imminent landing.  • Initial call within 4-10 minutes of the aircraft’s arrival  at the IAF. This call should give the aircraft’s location  as well as the crew’s approach intentions.  4-16  Figure 4-8.  Chey enne Regional (KCYS), Cheyenne, Wyoming, ILS or LOC RWY 27.  When operating on an IFR flight plan at an airport without  a functioning control tower, pilots must initiate cancellation  of the IFR flight plan with ATC or an AFSS. Remote  communications outlets (RCOs) or ground communications  outlets (GCOs), if available, can be used to contact an ARTCC  or an AFSS after landing. If a frequency is not available on  Since separation cannot be provided by ATC between  IFR and VFR traffic when operating in areas where there  is no radar coverage, pilots are expected to make radio  announcements on the CTAF. These announcements  allow other aircraft operating in the vicinity to plan their  departures and arrivals with a minimum of conflicts.  In addition, it is very important for crews to maintain a  listening watch on the CTAF to increase their awareness  of the current traffic situation. Flights inbound on an  instrument approach to a field without a control tower  should make several self-announced radio calls during  the approach:  NOT FOR NAVIGATION NW-1, 18 NOV 2010 to 16 DEC 2010 NW-1, 18 NOV 2010 to 16 DEC 2010
