ICAO Flight Plan Update

It only takes a cursory look at an ICAO flight plan form to get cranial blood-vessel spasms and the resultant migraine. Who starts a form at item seven? Yes, you really have to look up aircraft type codes in ICAO DOC 8643. Can equipment codes really use the whole alphabet, indecipherable by humans? Do they really have only one remarks box that serves as an explanation for nearly every other box on the whole form?Despite the forms flaws and seemingly unfathomable complexities, the FAA is committed to drag U.S. pilots to the ICAO flight plan. Since the ICAO form is already required for flights utilizing performance based navigation (PBN), flying in RVSM airspace, utilizing ADS-B services, and flights outside the U.S., everybody else might as well share the pain.

Key Takeaways:

  • The ICAO flight plan is a complex and often confusing form, designed by international consensus to satisfy diverse operational requirements for 191 nations and primarily for commercial airlines rather than individual general aviation pilots.
  • Despite its complexities, the FAA is making its adoption mandatory for all U.S. pilots, requiring familiarity with its structure, specific coding for aircraft and equipment, and routing conventions.
  • To simplify the process and avoid complications, pilots are advised to keep entries as straightforward as possible, use only essential equipment codes, and specifically avoid filing the "R" code for performance-based navigation (PBN).
