N787BA ACARS


Four ACARS messages on 10.081 MHz were intercepted in San Francisco today from N787BA on the Everett flightline:


1: Ground to Air, asking BOE787/N787BA to respond
2: Air to Ground, N787BA as BO0787 at 15:25:12
3: BOE787 giving a position report at KPAE
4: BOE787 giving another position report, confirming ICAO code AAAAA1
The BO0787 format uses Boeing's BO IATA code; the BOE787 uses their BOE ICAO code. ICAO 24-bit hex AAAAA1 translates to N787BA.
