1.3 Retrieve and open crew briefing package Captain / First Officer Jeppesen FliteDeck Flight number, date, departure station Loaded briefing package: flight plan, weather, NOTAMs, ATIS Briefing package retrieval within 2 min of sign-in; package currency ≤60 min old at review N N
Phase 2
2.1
Review METAR, TAF, and SIGMET reports Captain / Dispatcher Honeywell GoDirect Current METAR, TAF for departure/en-route/destination, SIGMETs Crew weather assessment and ceiling/visibility minima check Weather briefing completed ≥20 min before STD; 100% SIGMET acknowledgement logged N N
2.2 Assess destination and alternate minima Captain Jeppesen FliteDeck Terminal aerodrome forecasts, instrument approach plate minima, airline OpSpecs Alternate airport selection and additional fuel requirement Correct alternate selected per ICAO Annex 2 / FAR 121.619; fuel-to-alternate margin ≥45 min N Y
2.3 Confirm weather acceptable for planned departure Captain / Dispatcher Honeywell GoDirect Weather assessment, crew minimums, operational limits Go / No-Go weather decision; delay or reroute request if no-go Weather-related departure decision communicated to OCC ≥15 min before STD Y Y
Phase 3
3.1
Review computerised flight plan and fuel load Captain / Dispatcher NAVBLUE Filed ATC flight plan, optimised route, fuel figures from Dispatch Reviewed flight plan with crew acknowledgement Flight plan review complete ≥15 min before STD; fuel uplift variance ≤2% vs planned N Y
3.2 Review dispatch release for regulatory compliance Captain NAVBLUE Dispatch release document, OpSpecs authorisations, fuel release Crew review annotation; list of queries for Dispatcher Dispatch release co-sign rate without amendment ≥92%; amendment resolution time ≤10 min Y Y
3.3 Co-sign dispatch release with Dispatcher Captain / Licensed Dispatcher NAVBLUE Reviewed and agreed dispatch release Dual-signed dispatch release (FAR 121.663 joint responsibility established) Dispatch release signed ≥10 min before STD; 100% digital co-signature audit trail N N
Phase 4
4.1
Review NOTAM package for departure and en-route Captain / First Officer Jeppesen FliteDeck NOTAM filter output for departure airport, en-route waypoints, destination Annotated NOTAM list; crew awareness of active restrictions NOTAM review complete prior to departure; safety-critical NOTAMs (runway closures, ILS unserviceable) flagged 100% N N
4.2 Review MEL and CDL deferred item list Captain Boeing Toolbox / CAMP Aircraft tail number, active MEL/CDL deferrals, maintenance logbook Crew acceptance or rejection of aircraft with deferred items MEL review completion rate 100% prior to boarding; deferral-related delays <0.5% of departures Y Y
4.3 Confirm airworthiness release from Maintenance Captain / Maintenance Control AMOS by Swiss AviationSoftware Signed aircraft logbook, maintenance release certificate Airworthiness confirmed; aircraft released for service Maintenance release issued ≥45 min before STD; 100% release traceability in AMOS N Y
Phase 5
5.1
Conduct pre-flight exterior walk-around First Officer / Captain Jeppesen FliteDeck Completed maintenance release, pre-flight checklist Completed exterior inspection record; any defects raised Walk-around completed ≥30 min before STD; defect-to-report time ≤5 min N Y
5.2 Confirm final weight & balance load sheet Captain / Load Control Amadeus Altéa PSS Final passenger count, cargo weights, fuel load, trim settings Signed load sheet; CG within envelope confirmed Load sheet issued ≤15 min before STD; CG deviation from plan <0.5% MAC N Y
5.3 Obtain ATC clearance and departure slot Captain / First Officer SITA ACARS Filed flight plan, ATIS, ATFM slot allocation ATC route clearance; CTOT confirmed or delay calculated Clearance received ≥5 min before pushback; ATFM slot adherence ≥94% Y Y

Airline-Specific Risks & Pain Points

FAR Part 117 / EASA FTL limits require real-time cumulative duty tracking across time zones — late roster updates in Jeppesen Crew Management can create compliance gaps at sign-in
Fatigue Risk Management System (FRMS) data is not always integrated with real-time crew tracking; manual overrides by Crew Scheduling introduce compliance risk during IROPS
EFB synchronisation delays on congested airport Wi-Fi (especially at hub gates) can result in crews accessing stale briefing data — no automatic staleness alert in FliteDeck
Rapidly evolving convective SIGMETs issued by NOAA Aviation Weather Center can be uploaded to GoDirect with 10–15 min latency — crew may depart with outdated convective picture
Low-visibility operations (Cat II/III) require special OpSpecs approval in FAA WebOPSS; not all airports in the network have current CAT II/III plates loaded in FliteDeck for all aircraft types
Dispatcher and Captain may reach independent weather conclusions using different data sources (GoDirect vs airline wx feed) with no reconciliation workflow — leads to coordination delays at the gate
