NASA Study of An Automated Pilot Advisory System

A study of a Pilot Advisory System (PAS) concept for high density uncontrolled airports is described. The PAS concept will provide general aviation pilots with automatic audio voice airport and air traffic advisories in two-minute intervals and mid-air collision warnings as necessary. The system when installed will operate automatically without necessity for manual input. The PAS includes the options of fixed-base operator runway select, automatic restart and self-test, and remote inquiry of system status and messages.
