Lesson 20 - Aircraft Characteristics

Appendices A through C of FAA JO 7110.65, Air Traffic Control, reflect ICAO-approved aircraft type information.

The 7110.65 para. 2-3-6 requires, in both automated and non-automated environments, the use of the approved aircraft type codes contained in Appendices A-C to indicate aircraft type.

The information in these appendices is to be used for flight planning in the NAS.

Below is a list of the most commonly misused aircraft type identifiers. The aircraft type identifier is used by EDST to correctly probe the aircraft's speed. When EDST does not recognize an aircraft type identifier it probes the route of flight using a speed based on the aircraft's assigned altitude. This may result in the probing speed being hundreds of knots slower than the actual aircraft speed, which will then provide incorrect alerts. Even worse, EDST would fail to provide some actual alerts.
