Field guide
Operational brief
A dispatch release is the beginning of the decision, not the end of it.
Turn a generated operational flight plan into a defensible route, weather, alternate, performance and fuel decision.
On completion
01 / Read the release
Interrogate the plan before accepting it.
Confirm the flight number, aircraft variant, registration profile, weights, route, cruise level and weather cycle. A polished SimBrief document can still be wrong if its aircraft profile or departure time is wrong.
Trace the route on a chart, identify constrained airspace and review departure, destination and suitable alternate weather. Open operationally important NOTAMs rather than counting them.
- Verify aircraft profile and units
- Compare routing with current charts and restrictions
- Understand why each alternate is usable
02 / Fuel structure
Every fuel line has a job.
Read the plan as separate protections: taxi, trip, contingency, alternate, final reserve and any discretionary extra fuel. Do not treat the block figure as one undifferentiated number.
Weather, runway choice, anti-ice use, expected holding, remote alternates and oceanic uncertainty can change the margin. Use the planning policy represented by your aircraft profile and avoid inventing airline quantities.
03 / Performance
The route works only if both runways do.
Calculate takeoff and landing performance using the correct weight, runway, intersection, wind, temperature, pressure, surface condition, anti-ice state and configuration.
Recalculate after a runway change or meaningful weather update. Check that the resulting thrust, speeds and flap setting agree across the performance tool, flight-management system and takeoff brief.
04 / In flight
A dispatch plan remains alive after takeoff.
At regular waypoints compare actual time and fuel with the operational flight plan. Investigate a trend rather than waiting for the destination prediction to become critical.
‘Minimum fuel’ advises ATC that further delay could erode the protected reserve; it is not itself an emergency. If the protected final reserve can no longer be maintained to a safe landing, use the applicable fuel-emergency declaration.
- Record actual fuel and time
- Update destination and alternate weather
- Make diversion decisions while useful options remain
Release to line
Five checks.
Then fly.
Aircraft profile, weights and units verified
Route and significant NOTAMs reviewed
Destination and alternate weather acceptable
Fuel components understood
Takeoff and landing performance cross-checked

Operational details change. Verify revision dates and use current charts, aircraft documentation and active ATC instructions for every flight.
