The Most Important Document You Never See
Before any Part 135 charter flight departs, a flight release must be issued. This is not a formality. Under 14 CFR 135.77, no certificate holder may operate a flight unless a person authorized by the operations specifications (OpSpecs) has issued a flight release for that specific flight. The release confirms that the aircraft, crew, weather, fuel, route, and operational conditions meet all regulatory requirements. If the release is not issued, the flight does not go. The FAA assesses civil penalties starting at $11,000 per violation for flights conducted without a valid release.
Charter clients never handle the flight release. It moves between the dispatcher (or operations control) and the pilot-in-command (PIC). But understanding what it contains explains why your operator sometimes delays a departure, changes an aircraft, or cancels a trip that looks flyable on your weather app. The release is where operational reality and regulatory compliance intersect.
What the Flight Release Contains
A compliant flight release under Part 135 includes the following elements. Some operators use paper forms; most use electronic dispatch systems that auto-populate data from flight planning software. Regardless of format, the release must contain:
- Company name and certificate number
- Aircraft tail number, type, and current airworthiness status
- Flight number or trip identifier
- Names of the PIC and SIC (if required)
- PIC currency: instrument proficiency, recency of experience, medical certificate status
- Departure airport, destination, and all planned alternates with ICAO identifiers
- Planned route of flight (airways, fixes, or direct routing)
- Minimum fuel required (including IFR reserves, alternate fuel, and contingency)
- Current and forecast weather at departure, en route, destination, and alternate airports
- MEL items: any deferred maintenance items and their operational impact
- NOTAM review for departure, arrival, en route, and alternate airports
- Weight and balance: passenger count, baggage, fuel load, CG position
- Name and signature of the person issuing the release
- Time and date of release issuance
The flight release is not a flight plan. The flight plan (filed with ATC) contains routing and altitude information. The flight release is an internal operational authorization that confirms the flight can be conducted safely and legally. An operator can file a flight plan without issuing a release. But the flight cannot depart without both.
Who Can Issue a Flight Release
Under 14 CFR 135.77, the flight release must be issued by a person specifically authorized in the certificate holder's operations specifications. In smaller Part 135 operations (10 or fewer aircraft), the Director of Operations (DO) or Chief Pilot often holds release authority. In larger operations, dedicated dispatchers or operations control specialists are authorized.
The release authority carries personal liability. If the releasing officer authorizes a flight that violates weather minimums, crew duty time limitations, or aircraft airworthiness requirements, that individual (not just the company) faces FAA enforcement action. This is why experienced dispatchers sometimes push back on flights that pilots want to accept. The dispatcher sees the regulatory picture; the pilot sees the immediate conditions.
The PIC's Override Authority
The PIC always retains final authority for the safe operation of the flight under 14 CFR 91.3. If the dispatcher issues a release but the PIC determines conditions are unsafe after arriving at the aircraft or during the flight, the PIC can cancel or divert without the dispatcher's concurrence. This authority flows one direction: the PIC can always say no. The PIC cannot, however, depart without a valid release. The system requires dual concurrence for departure but allows unilateral refusal.
