Project brief

This comprehensive Flight Management System was designed for a 19-seat regional turboprop aircraft. The system performs real-time 4D trajectory planning using GPS/INS sensor fusion, manages fuel prediction, optimizes routing via waypoint databases, and communicates over ARINC 429 dual-channel data bus to cockpit displays and navigation receivers. The FMS interfaces with VOR/DME/ILS radio navigation aids and a Class 2 FMS RNAV computer.

The case study connects navigation estimation, performance prediction, and avionics integration. The explanatory view illustrates the functions named in the project record.

The engineering challenge

Coordinate navigation, route intent, and aircraft performance within one flight management architecture.

Engineering approach

  1. Fuse the stated navigation sources into a consistent aircraft state.
  2. Organize waypoint, fuel, and trajectory functions around the active flight plan.
  3. Exchange guidance and display data through the ARINC interfaces.
