1.4 Dispatch Release Elements, Signatures & Recordkeeping

Dispatch Release, Concurrence, and Flight Documents

A dispatch release is the domestic/flag flight authorization prepared through the carrier's approved dispatch system. It is one part of a flight's documentation, alongside the operational flight plan, ATC flight plan, load manifest, maintenance information, and weather package. A complete airline release packet can include considerably more information than the minimum list in § 121.687. Distinguishing legal minimums from additional carrier-required information prevents misleading quiz answers.

The statutory contents

Section 121.687(a) lists the following minimum information concerning each flight:

Paragraph (b) requires the release to contain or have attached the latest available weather reports, available forecasts, or a combination for the destination, intermediate stops, and alternates at the time the PIC and dispatcher sign. Additional weather considered necessary or desirable may be included. The rule does not itself enumerate every METAR, PIREP, or SIGMET as a separate mandatory release field for every flight.

MEL/CDL restrictions must be assessed and conveyed through the approved operation. They are not a seventh item in § 121.687(a). For example, an inoperative anti-ice component may require route changes, and a missing fairing may require a fuel correction. A release packet lacking those required operational corrections is deficient even though the missing restriction is not a named item in the statutory release-content list.

Signatures and safety concurrence

Section 121.663 requires the PIC and dispatcher to sign the release only if both believe the flight can be made safely. The dispatcher may delegate signing authority for a particular flight but may not delegate the authority to dispatch. An electronic method is subject to the carrier's authorized procedures and records controls. FAA AC 120-78B provides current guidance on electronic signatures, recordkeeping, and manuals; the previous A revision should not be presented as the current reference.

The release and ATC clearance have different functions. Dispatcher/PIC concurrence supplies company authorization; ATC authorizes the traffic movement and route under its clearance responsibilities. Neither document automatically substitutes for the other. A route change can require both company evaluation/amendment and an ATC clearance, while a gate hold may require updated fuel and weather evaluation without an immediate airborne ATC reroute.

Intermediate stops and changing conditions

The domestic intermediate-stop rule is § 121.593. When an airplane lands at an intermediate airport specified in the original release and remains there for not more than one hour, the exception to new specific dispatch authorization applies. Beyond that time, obtain the required dispatcher authorization. The flag rule in § 121.595(b) requires redispatch after more than six hours on the ground. Supplemental § 121.597(c) similarly requires a new flight release after more than six hours.

These provisions concern an intermediate airport, rather than creating a universal one-hour expiration for any departure-gate delay. Even within the time exception, current conditions can require further action. Recheck weather, runway status, fuel, aircraft defects, and crew qualifications. A dispatch release is not permission to continue an unsafe plan because a clock has not yet crossed a threshold.

Section 121.631 addresses amendments and redispatch. Before changing a destination or required alternate, verify the applicable weather, fuel, performance, and authorization requirements, then record the amendment. Routine ATC vectors do not automatically demand a new signed release for every turn; apply the approved procedures and assess whether the plan remains safe and compliant. If a materially different route consumes additional fuel, calculate the effect before accepting an assumption that the original reserve remains adequate.

Documentation workflow

A practical preflight review starts with a version-controlled packet:

1. Confirm aircraft identity and the applicable operation type.
2. Check route, departure/destination/alternate selection, and ETOPS diversion time where required.
3. Verify minimum takeoff fuel and taxi allowance against actual uplift and anticipated delays.
4. Validate performance and the load manifest against current aircraft status and runway conditions.
5. Review the weather package and available NOTAMs, including their issue and validity times.
6. Obtain the required safety concurrence and retain the approved record.

Suppose a domestic flight stops for 45 minutes at an intermediate station, but deicing extends the ground time to 65 minutes. Because the one-hour intermediate-stop exception no longer applies, the dispatcher provides renewed authorization using current information. If taxi fuel has increased by 600 pounds, the fuel decision must also be recalculated. A cosmetic timestamp change without reviewing the operational inputs would not resolve the underlying problem.

Domestic and flag retention

Under § 121.695(a), the PIC carries to the destination a copy of the dispatch release, flight plan, and completed load manifest or permitted information from it. The carrier keeps the required copies for at least three months under paragraph (b). The flight-deck requirement is in paragraph (a), not paragraph (b). An authorized electronic system must preserve accessible, accurate records under its approved procedures.

The load manifest contains data required by § 121.693, including weight and balance information. A dispatch release's minimum fuel entry does not prove that the airplane is within zero-fuel, takeoff, landing, and center-of-gravity limits. During the practical test, demonstrate those checks explicitly rather than treating document existence as evidence that someone else made a correct calculation.

Supplemental retention differs

Section 121.697 requires the original or a signed copy of the load manifest, flight release, airworthiness release, pilot route certification, and flight plan aboard to the destination. It also describes copies retained at the principal base and procedures for flights originating elsewhere, including limited temporary retention at the departure station. The principal-base minimum retention is three months. Do not reduce the supplemental list to the three domestic/flag documents or assume all dispositions are identical.

Amendments, arrival, and audit trail

Consider a flight released with Providence as its destination alternate. Updated forecasts show that alternate below its required planning minima. The dispatcher and PIC evaluate another airport, its fuel requirement, wind and runway suitability, then record the required alternate change under the approved amendment procedure. The new alternate must be operationally reachable, not merely have a favorable METAR.

At arrival, verify completion and retain the original packet with its amendments. Identify any irregularity report and separate FAA/NTSB notifications from normal document retention. A three-month retention rule does not postpone an immediate accident notification or extend the emergency-deviation reporting deadline. On a practical exercise, finish by explaining who receives the documents and how the final version can be distinguished from an obsolete release.
