AI-Assisted Flight Planning: A Verification Workflow for GA Pilots

An automated summary can make a long briefing easier to scan. It cannot know that every source is current, every operational constraint is represented or every conclusion fits the pilot, aircraft and flight.

Under 14 CFR 91.103, the pilot in command must become familiar with all available information concerning the flight. The rule does not create a different responsibility when the interface is conversational, predictive or marketed as artificial intelligence.

The useful question is therefore not whether an AI output sounds convincing. It is whether the pilot can trace every decision-relevant statement back to current weather, aeronautical, aircraft or operational information.

Start with the FAA briefing structure

FAA Advisory Circular 91-92 provides a self-briefing roadmap covering planning, weather interpretation, risk identification and mitigation. The FAA's Aeronautical Information Publication also says pilots may use automated resources and flight-planning applications for self-briefing, while still gathering the information vital to the flight and assessing whether it can be conducted safely.

Use that structure as the control. An AI summary is one interface inside the workflow, not the workflow itself.

Step 1: Freeze the inputs

Before asking a tool for an assessment, record the inputs that determine the answer:

• proposed route, altitude and departure window;
• departure, destination and alternate airports;
• aircraft registration and performance basis;
• fuel assumptions and reserve policy;
• pilot qualifications, currency and personal minimums;
• runway, equipment and navigation requirements; and
• the briefing time and source-update times.

Without a frozen input set, two summaries can disagree simply because they evaluated different flights.

Step 2: Require source visibility

The output should identify the underlying products rather than hide them behind a conclusion. For a US flight, that may include current observations and forecasts, advisories, PIREPs, NOTAMs, TFRs, airport data and the applicable charts.

ForeFlight says its graphical briefing is derived from government sources and stores a timestamped briefing record. That is a vendor statement about its briefing product. It does not mean every separate conversational feature, third-party plug-in or copied summary carries the same source set or record.

Ask four questions of any automated summary:

1. What source produced this statement?
2. When was that source issued or updated?
3. What data was unavailable or omitted?
4. Can the original product be opened and checked?

If the answer is unclear, treat the statement as a prompt for investigation, not an operating fact.

Step 3: Verify the operationally important claims

Do not spend equal time on every sentence. Verify the items that can change the decision or margin:

• ceiling, visibility, wind and convective timing;
• icing, turbulence and terrain exposure;
• runway closures, lighting, navigation-aid and approach availability;
• temporary flight restrictions and route constraints;
• alternate requirements and fuel;
• aircraft performance and equipment status; and
• the time at which conditions could cross a personal or regulatory limit.

Open the source product and compare it with the summary. A fluent restatement of stale data is still stale.

Step 4: Separate description from recommendation

"The TAF forecasts a 1,000-foot ceiling" is a description of a source. "This flight is low risk" is a judgment built from assumptions about the pilot, aircraft, alternatives and tolerance for uncertainty.

Keep those layers separate. A useful briefing note can show:

Layer	Example
Source fact	Forecast, observation, NOTAM or charted limitation
Interpretation	What the source may mean for this route and time
Threshold	Regulatory, aircraft or personal limit
Decision	Delay, reroute, add fuel, change alternate or do not depart

The pilot owns the final layer.

Step 5: Look for disagreement and missing data

An automated tool is most useful when it helps find a conflict, not when it compresses uncertainty into one score.

Check for:

• observation versus forecast disagreement;
• model or forecast changes across issue times;
• a route hazard not represented at the departure or destination;
• a NOTAM that changes runway or approach availability;
• data older than the intended flight window; and
• an unsupported inference presented as a source fact.

When the picture is unclear, use Flight Service or another appropriate operational source in a consultative role. AC 91-92 explicitly preserves that option.

Step 6: Recheck before departure and in flight

A good briefing is time-bound. Weather, NOTAMs, TFRs, runway status and aircraft condition can change after the first review. Record the refresh point and the triggers for obtaining new information.

The practical standard is simple: automation may reduce the work required to locate and organize information, but it does not reduce the amount of responsibility carried by the pilot in command.
