Enables streamlined virtual flyability checks and satellite availability analysis

FPSAT (Flight Procedure Satellite Analysis Tool) is an AIM (aeronautical information management) software tool for performing virtual flight inspections in order to check the flyability of RNAV procedures, the coverage and accuracy provided by the navigational aids infrastructure along the whole of a procedure’s trajectory and to identify any factor that may affect navigational aid performance.

FPSAT is a pre/post processor that enables procedure specialists to:

FPSAT Flight Procedure Satellite Analysis Tool
  • Check how the Flight Management System (FMS) will fly the coded procedure by comparing the nominal trajectory and the simulated trajectory, taking into account ARINC path and termination (and related attributes), the type of aircraft as per EUROCONTROL BADA files, and kinematic and weather restraints
  • Verify GNSS (global navigation satellite system) signal in space performance (GPS, SBAS, GBAS) along a trajectory
  • Assess the signal continuity, coverage and couples’ availability of DME/DME navigation along a trajectory
  • Visualize Air Traffic Services (ATS) related geographic data, perform diagnostics and check the results for their functionality
  • Review procedures to optimize navigation performance, cost and environmental impact

ICAO Docs 8168, 8071 and 9906 describe the activities required for the ground validation of RNAV (area navigation) flight procedures. These include checking the coverage and accuracy provided by the navaid infrastructure along the whole of a procedure’s trajectory, and identifying any electromagnetic interference that may affect the performance of the navaid infrastructure.

A virtual flight inspection of an RNAV procedure may also be used to verify and optimize:

  • the obstacle environment where the procedure is located
  • the flyability of the procedure
  • The ARINC 424 coding of the procedure by fixing the geometry of the waypoint/nominal track
  • The effects of different weather (wind and temperature) conditions

FPSAT provides the means to perform these inspections and also covers the need to verify the availability and usability of navaids (satellite and ground based signals) along a flight path:

  • For a given realistic aircraft attitude
  • For a specific aircraft category
  • For different take-off loads and weather conditions
  • Considering the variability of the GPS constellation
  • For different types of GPS augmentation
  • Taking into account changes in the electromagnetic environment due to interaction with potential sources of interference

FPSAT - Main Benefits

User-friendly cost effective method for ground validation. Capacity to input procedures, supporting navaids, waypoints and obstacles

Improves safety through the early identification of potential problems in the design of a procedure

Reduce costs by minimizing the need to use flight validation to optimize procedure

Can be integrated into the flight procedure design process (AIXM 4.5/5.1 compliant) before a flight procedure is completed
