openfdm is a production-ready Python package for running a Flight Data Monitoring (FDM)/Flight Operations Quality Assurance (FOQA) program, including the identification of safety events.
It provides:
- An implementation of a FDM pipeline for batch processing of safety events across multiple flights;
- A rule engine with base events and an extensible software architecture;
- A standardized flight dataframe and parameters model;
- Extensible connectors for loading flights and saving outputs of business rules.
The easiest way to install openfdm is using pip from your virtual environment.
Directly from GitHub:
pip install git+https://github.com/coelhosilva/openfdm.git
This is a sample usage of the package for constructing a FDM pipeline. It loads two sample flights from disk and calculate the outputs of the following safety events: hard landing, bounced landing, and landing in a crab.
from openfdm.rule_engine.safety import (
HardLandingEvent,
BouncedLandingEvent,
LandingInACrabEvent,
)
from openfdm.processor.pipeline import FlightDataMonitoringPipeline
from openfdm.processor.connectors.flight_loader import SampleFlightLoader
from openfdm.processor.connectors.output_connector import ConsoleOutputConnector
fdm_pipeline = FlightDataMonitoringPipeline(
flight_loader=SampleFlightLoader(),
fdm_events=[
HardLandingEvent(),
BouncedLandingEvent(),
LandingInACrabEvent(),
],
output_connector=ConsoleOutputConnector(),
)
fdm_pipeline.run()We welcome and encourage new contributors to help test openfdm and add new functionality. Any input, feedback,
bug report or contribution is welcome.
