>not all planes that fly need to have flight plans and transponders Technically true but since 2020 almost all aircraft are required to have transponders to fly in controlled airspace. You could have a small GA aircraft without a transponder and only fly in and out of small uncontrolled air strips, but in practice most aircraft are going to have ADS-B out now. https://www.faa.gov/air_traffic/technology/equipadsb/researc... |
