<<codelist>> A code that defines a specific type of flight path and a specific type of termination of that flight path. Although we agree with the ARINC idea that procedures should be designed with the aim to permit FMS equipped aircraft to fly tracks instead of procedural headings, for the time being we must allow all representation of these procedures (especially reversal procedures) as they are published by the States. This is the explanation of the differences between the allowable values for attributes in this domain and the ARINC leg types.
