Operational Flight Plan Monitoring: Keeping the Plan Visible as Conditions Change

Every flight begins with an Operational Flight Plan (OFP). It is prepared before departure, checked by qualified people and released under approved procedures, and it carries the structured expectation for the flight ahead.

The plan sets out flight identity, route and waypoints, the fuel ledger from taxi and trip fuel through contingency, alternate and final reserve, the planned weights, the alternates, the cruise and step-climb profile, the performance assumptions, the planned timing and the winds and temperatures used in planning.

Once the aircraft moves, operating conditions begin to differ from planning assumptions. Taxi and runway flow, weather, winds, route changes, air traffic control instructions, holding, airport constraints, flight-level availability and arrival sequencing all shape the flight that is actually flown.

The opportunity is not to replace the Operational Flight Plan. It is to keep the plan visible as operating conditions change, and to close every flight against the same baseline so airline teams can see what is recurring.

Challenge: A Structured Plan in a Continuously Changing Operation

“Airlines already have trusted flight-planning and dispatch systems. The opportunity is to keep the Operational Flight Plan visible as conditions change, reconcile each completed flight against the same baseline, and help teams learn from recurring operational patterns without replacing airline control.”
— Samar Khan & Tony Mamakos, TripAI

The OFP is a trusted preflight baseline, and it is not weakened by the fact that conditions move. Weather, flow and sequencing are normal operations, so a difference from plan is neither automatically avoidable nor evidence of weak planning.

Route, fuel, time, reserves and profile are related, but their signals often live in separate systems. A number above or below plan does not explain its own cause, and one flight may reflect a single event rather than a pattern.

Post-flight review becomes more useful when every flight is closed using consistent definitions and clear source lineage, and teams need that reconciliation without any weakening of dispatch authority.

The challenge is not producing another flight plan. It is preserving one trusted baseline, showing where operational reality is moving away from it, and creating a consistent record that airline teams can review after the flight.

Solution: A Read-Only Monitoring Layer Built Around the Airline's OFP

TripAI reads the airline-controlled OFP as the baseline, normalises it into traceable fields, connects available movement and operational context, compares planned with observed progress and reports material differences in plain operational language, then preserves each completed flight as one plan-versus-observed record. The approach combines operational analytics, source-aware data integration and AI-assisted explanation.

Live Monitor: What Is Changing Now

The monitor compares the OFP baseline with available operational information and reports fuel-plan drift, estimated arrival-time drift, route drift, reserve position, alternate viability, profile conformance, weather context and airport and runway context.

Each source is held to its real role. Fuel values need an approved OFP baseline, and aircraft-reported fuel comes from airline systems or the Aircraft Communications Addressing and Reporting System (ACARS) where connected. Automatic Dependent Surveillance-Broadcast (ADS-B) supports movement, altitude, speed and phase awareness, never fuel truth. Planned cruise is stated in Flight Levels (FL) and observed altitude in feet. The monitor explains what is changing. It does not issue a dispatch release.

Flight Closeout: What Happened Against Plan

After arrival the flight is reconciled against the same baseline: planned and observed block, taxi-out, airborne and taxi-in time, planned and sampled route distance, planned and reported or modelled fuel boundaries, reserve protection, profile progression and data quality.

The record keeps its layers separate: plan, observed movement, aircraft-reported data, modelled values and scenario attribution. Landing fuel and on-block fuel mark different operational boundaries and are not mixed, and a burn below plan is reported as plan variance, never as a saving.

Comparable-Flight Review: One Event or a Repeated Pattern

One flight rarely settles a question. Completed records can be compared by route, airport pair, aircraft family, fleet, weather regime, departure bank, hub or mission profile, over a period the airline selects rather than a fixed window.

That shows whether a result is a one-off disruption, a recurring route residual, a weather or airport-flow effect, a profile pattern, a repeated planning bias or a data-quality issue. Comparison depends on validated airline OFPs, and a schedule delay does not by itself indicate fuel inefficiency.

Where the Information Comes From

Each source has a defined role, and the interface shows which are actually connected.

• Operational Flight Plan or dispatch data: route, fuel plan, weights, alternates, reserves, profile, waypoints, planned timing, and cost-index or performance assumptions where available
• ADS-B: independent movement signal for position, altitude, ground speed, track and phase
• Weather: winds, temperatures, turbulence, convection, icing and en-route context
• Airport state and Notice to Air Missions (NOTAM): runway state, restrictions, closures and flow
• ACARS: official gate-out, takeoff, landing and gate-in (OOOI) events and aircraft-reported fuel
• Load control and Weight and Balance (W&B): actual weights, load distribution and approved limits
• Quick Access Recorder (QAR) or Flight Data Monitoring (FDM): post-flight validation and calibration, not required for live monitoring

What the Airline Receives

• Live visibility of how the operation is tracking against the released plan
• One traceable planned-versus-observed record for every completed flight
• Fuel, time, route, reserve and profile differences explained in plain language
• Route, airport, weather, profile and fleet patterns a single flight cannot show
• Evidence for planning review, with attribution that improves as airline data is validated

The result is a continuous record connecting the released plan with what the operation actually did, without adding another plan for airline teams to reconcile.

TripAI monitors, compares and explains. The airline's Operational Flight Plan, dispatch systems, authorised personnel and standard operating procedures remain controlling.

• Airline-controlled OFP baseline
• Read-only monitoring
• Source-specific confidence
• Configurable operational thresholds
• Full audit trail
• No autonomous replanning, re-dispatch or override

Dispatch, the Operations Control Centre (OCC) and the flight crew keep their existing authority, and no causal claim is made when source data is incomplete.
