No candidate airport is within 25° of the current heading (246°, all Δhdg > 79°). Only KSTS has Δhdg 79°, which is less than 90°, so it escapes the 'behind' rejection. The aircraft appears to have recently departed the LA area (from K0L7 to KLAX on May 25) and is now at 9275 ft climbing west-southwest, likely on a departure procedure that will turn north toward Sonoma County, a recurring destination. Past mistakes for this person include missing KLAS when guessing KPBI, but KSTS is a frequent destination and the only plausible candidate from the table, so it is selected with modest confidence.
