Data in this repository includes:

• Aircraft data: Collected from open literature.
• Engines data: Primarily from the ICAO emission data-bank, including fuel flow and emissions.
• Drag polar model data: Exclusively derived from open data (reference).
• Fuel mode data: Polynomial models derived from the acropole model by @JarryGabriel.
• Kinematic data: The kinematic model describes speed, altitude, and vertical rate (reference).
• Navigation data: Airport and waypoints obtained from X-Plane.

The OpenAP Python library includes the following packages:

• prop: module for accessing aircraft and engine properties
• thrust: module for computing aircraft thrust
• drag: module for computing aircraft drag
• fuel: module for computing fuel consumption
• emission: module for computing aircraft emissions
• kinematic: module for accessing WRAP data
• aero: module for common aeronautical conversions
• nav: module for accessing navigation information
• segment: module for determining climb, cruise, descent, level flight
• phase: module providing identification of all flight phases
• traj: module contains a set of tools for trajectory generation
