Current track 100.43° aligns perfectly (Δhdg 0°) with KTTN (Trenton) at 397 nm. The aircraft is returning east from recent Midwest activity (KGSP→KBEH), and KTTN was used on 2026-06-14 after a short hop from home base. Past predictions erroneously favored KIAD, but the actual destinations were often KTTN or KMMU; this self-correction biases toward the perfectly aligned, recently-visited KTTN. KMMU (home, 5° off) and KIAD (20° off) are strong alternates given they are also within the 25° alignment window and appear in the recurring or recent history.
