Last months clinic began a detailed look at the reports we are required to give ATC or FSS during an IFR flight. Specifically, we began looking at the reports other than the position reports required by 14 CFR 91.183(a), which well cover separately. The remaining reports come from three sources: 14 CFR 91.183 (paragraphs b and c), 14 CFR 91.187, and AIM 5-3-3.
IFR flights require pilots to make mandatory reports to ATC or FSS, categorized by regulations and the AIM, and commonly remembered through the "MARVELOUS VFR 500" mnemonic.
These reports include crucial operational changes such as missed approaches, vacating assigned altitudes, reaching or leaving holding fixes, and significant changes in true airspeed or estimated time of arrival.
Pilots must also report equipment malfunctions (radio, navigation), unforecast or hazardous weather conditions, inability to maintain a 500 feet per minute climb/descent rate, and any other information relating to the safety of flight.
While most reports are required at all times, specific ones like ETA corrections and reports for the final approach fix or outer marker are only mandatory when not in radar contact.
