Lost communications create stress and confusion. In Safer Pilot Challenge Day 4, Jason Schappert explains how pilots manage radio failures calmly. Lost communications require logic, preparation, and discipline. Pilots must troubleshoot first, then follow procedures.
Troubleshooting Before Declaring Lost Communications
Many lost communications events start with simple errors. Incorrect audio panel settings cause confusion. Volume knobs and intercom selections often create silence. Pilots must verify frequencies and headset connections. Push-to-talk switches can fail. Stuck microphones block transmissions. Pilots should continue transmitting in case ATC hears them. Monitoring nearby weather frequencies confirms receiver function.
Lost Communications Under VFR
True lost communications require confirmed failure. Under VFR, pilots should continue visually and land as soon as practical. FAR 91.185 allows pilot judgment during these situations. Pilots should avoid complex airspace when possible. Uncontrolled airports simplify arrivals. Observing traffic patterns replaces radio coordination. All exterior lights should remain on for visibility. Pilots should squawk 7600 if electrical power remains. Complete electrical failure prevents transponder transmission.
Light Gun Signals and Alternate Communication
Towered airports use light gun signals during lost communications. FAR 91.125 outlines signal meanings. Pilots must know these signals before flight. Pilots can also use cell phones when available. Many chart supplements list tower phone numbers. Bluetooth headsets often work independently of panel power.
Lost Communication Under IFR
IFR lost communications follow a strict sequence. Pilots use the AVEF route hierarchy. Assigned routes take priority. Vectored routes follow next. Expected routes come next. Filed routes apply last. Altitude selection uses the highest option. Pilots compare assigned, expected, and minimum altitudes. This rule protects terrain and traffic separation. Approach timing depends on clearance limits. Pilots descend near the expected clearance time or estimated arrival. Filing to an approach fix simplifies execution.
Preparation Prevents Panic
Lost communications rarely surprise prepared pilots. Handheld radios provide redundancy. Headset adapters improve usability. Pilots should rehearse procedures regularly. Confidence replaces panic through preparation. Lost communications become manageable events, not emergencies.
