What This Type of Data Looks Like
Civil aviation airport ledger data is sourced from flight operation management systems, ground support systems, passenger service systems, and cargo warehousing systems. Data updates follow two cadences: Real-time data such as flight takeoffs and landings, and passenger throughput, is updated within 1 minute after the associated event completes. Non-real-time data such as maintenance equipment and consumable inventory is updated on a natural day basis.
Individual ledger documents are split by business module. They include fields including flight number, takeoff and landing time, aircraft model, passenger capacity, baggage throughput, equipment number, and consumable stock. Field units include person-times, tons, minutes, sets, and other standard units.
Constraints for Tool Calling and Plugin Workflows
The real-time update feature of civil aviation airport ledgers requires tool calling response delays to match business timeliness. Otherwise, latest flight or maintenance data cannot be synchronized. Multi-source heterogeneous data sources require plugin configuration to support cross-system data source association. This prevents a single call from only retrieving ledger information from one business module. The multi-field, multi-unit document structure requires clear field extraction rules during tool calling. This prevents returning unitless pure values that cause subsequent summary errors. The batch summary requirement for large ledgers requires plugins to support paginated calling and result concatenation. This prevents data overload from single requests.
Configuration Guidelines
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
toolChoice | Auto-select tool | Adapts to the need for multi-data-source calls for ledger summary, no manual tool specification required |
| Maximum response delay | 3–5 seconds | Matches the update timeliness requirements of real-time civil aviation airport ledgers |
| Data source association rules | Bind corresponding systems by business module | Matches the multi-source heterogeneous characteristics of ledger data, avoids cross-module data confusion |
| Field extraction rules | Retain original fields and units | Prevents unit inconsistency errors during ledger summary |
| Result concatenation threshold | 1000–1500 characters | Adapts to the average document length of a single civil aviation airport ledger, avoids truncating critical information |
| Workflow call configuration | Bind specified workflow ID and API key | Meets actual needs for calling specified workflows, simplifies cross-service forwarding configuration |
Three Common Misconfigurations
- Phenomenon: After calling a tool, the returned text stream is unformatted plain text. After front-end parsing, only the full paragraph is displayed, without splitting by ledger fields. Cause: Field extraction rules are not configured, or structured output format is not enabled.
- Phenomenon: After deploying FastGPT with Docker, the system plugin configuration directory cannot be found, and custom ledger summary tools cannot be registered. Cause: The plugin registration directory was not created in advance, or the corresponding directory was not mounted in the deployment command.
- Phenomenon: Calling a workflow after cross-service forwarding fails, returning a workflow not found or permission error. Cause: The workflow ID and API key were not correctly bound, or necessary call parameters were not passed through by the intermediate service.
How to Verify Successful Configuration
- Initiate a test call, check if the returned result includes the specified ledger fields and units, and verify consistency with the original data in the data source.
- Simulate a real-time ledger update scenario, verify that the tool call response delay meets the preset business timeliness requirements.
- Check that the plugin registration directory and configuration files exist, confirm that custom tools can be properly loaded and called in the system.
- Call the bound workflow, verify that the preset ledger summary process can be triggered correctly, with no path or permission errors.
