Flight locating requirements
Read the official ruleThis regulation requires Part 135 operators to have a system for tracking flights when the pilot doesn't file an FAA flight plan. The tracking procedures must collect at least the same information required for a VFR flight plan (aircraft ID, route, fuel on board, etc.) and ensure someone can notify search and rescue if the aircraft becomes overdue or missing.
If a flight will operate where radio communication isn't possible, the operator must know where the aircraft will be, when, and when communications are expected to resume. All flight locating information must be kept at the company's main office or another designated location until the flight is complete.
Operators must provide their assigned FAA inspector with a copy of these procedures unless they're already included in a required manual. This ensures someone always knows where company aircraft are operating, even on flights without official flight plans.
