Plain English Meaning

These are the basic, single-line entries in the navigation database that describe one segment of a flight procedure. Each entry holds everything needed for that segment in one place, without needing extra lines to finish the description.

Full Definition

In the ARINC 424 navigation database specification, simple route records are records that define a procedure leg using only the standard route data fields, without requiring additional continuation records to describe the leg. They contain all the information needed to fly the leg — such as the path terminator, waypoint, altitude, and speed constraints — within a single record entry.
