Advisory only — evaluates visibility ≥ 3 SM and vertical cloud clearance (500 ft below clouds) against a 400 ft AGL ceiling (§107.51). Horizontal cloud clearance (2,000 ft) is not checked — verify that separately. The TFR check is a state-level match, not a precise boundary check, and airport contact links point to third-party lookups, not verified phone numbers. Always confirm TFRs, waivers, and ATC contact independently before flight.
