When filing for a drop-in approach at an airport that has numbers as their ICAO, how is it entered on the ROUTE OF FLIGHT?

• A. Enter it as the airport identifier without changing it
• B. Change to the IATA code
• C. Spell out the city name
• D. Use the country code

Answer: (A)

The designator you file for an airport in the ROUTE OF FLIGHT is its ICAO airport identifier, and any numbers that appear in that code are part of the identifier you enter. This routing field is built around the exact, published ICAO code so ATC and the navigation databases can unambiguously identify the airport. Using the IATA code, spelling out the city, or the country code would not reliably point to the correct airport in the flight plan, and could cause confusion or misidentification, especially when multiple airports exist in close proximity. So you enter the airport exactly as its ICAO code shows, including any digits.
