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: 

• 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. 

• 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. 

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
