DuPont

The aircraft is at 41,000 ft heading 54° toward KILG (Δhdg 14°, ALIGNED, 207 nm). KILG is the home base and a frequent destination for DuPont. Past predictions show a pattern of over-guessing non-home airports (e.g., KORD, KIAD) when the actual destination was KILG, so I bias toward home. KTTN (Δhdg 14°, 259 nm) is a recent alternate, and KIAD (Δhdg 31°, 123 nm) is a recurring destination slightly off-track but plausible.
