Communication Failure Recognize/Troubleshoot VFR/IFR Clearance Limit Continue to reestablish comm. Squawk 7600 Comm. Failure FAR 91.185 Route to Fly A Assigned (in last ATC clearance received) V Vectored (direct route from point of failure to fix, route or airway specified) E Expected (route ATC has advised to expect) F Filed (in absence of assigned, use filed) Comm. Failure FAR 91.185 (cont.) M Minimum IFR Altitude E Expected as advised by ATC A Assigned by ATC Altitude, highest of the Route segment being flown Comm. Failure FAR 91.185 (cont.) If failure occurs in VFR conditions, or if VFR is encountered after the failure, flight is continued VFR with a landing as soon as practicable. Comm. Failure FAR 91.185 (cont.) Leaving the Clearance Limit When Clearance Limit is a fix from which an approach begins, commence descent or descent and approach as close as possible to the EFC time if one has been received. If one has not been received, as close as possible to the ETA as calculated from the filed or amended (with ATC) ETE. Comm. Failure FAR 91.185 (cont.) Leaving the Clearance Limit (cont.) If the clearance limit is not a fix from which an approach begins, leave the clearance limit at the EFC time if one has been received, or if none has been received, upon arrival over the clearance limit, and proceed to a fix from which an approach begins and commence descent or descent and approach as close as possible to the ETA as calculated from the filed or amended (with ATC) ETE. Comm. Failure (cont.) Arriving at the holding fix/clearance limit When arriving early hold at IAF Hold as published on inbound course Hold on PT side at: assigned, MEA Consider: Q: What is the fix from which an approach begins? Q: How does a pilot determine where the fix for a particular approach is? Comm. Failure (cont.) Consider: (cont.) Q: What if the pilot never receives info on approach to be used? Q: How does a pilot determine which approach should be used? Q: What if the approach has
