FMS Navigation Database

Universal Avionics receives FMS navigation data from multiple data suppliers: specifically, Jeppesen Sanderson, Inc. (Jeppesen) and NAVBLUE Limited (NAVBLUE).

Jeppesen holds a Type 1 LOA from both the FAA and the European Aviation Safety Agency (EASA).

NAVBLUE holds a Type 1 LOA from EASA.

  FMS Navigation Database Type 2 LOA

The navigation databases may contain customer tailored data not originating from a State authority, such as private airports and runways or private arrival or departure procedures. The end user has the responsibility to verify the suitability of this data for the intended operation.


InSight Terrain Database

The InSight Terrain database is comprised of three sub-databases: Terrain Elevation; Terrain Coverage; and Terrain Cultural Chart Features. InSight Terrain Elevation is produced by Universal Avionics from multiple data products. UA validates elevation data and is the first RTCA DO-200A compliant participant in the Terrain database aeronautical data chain. UA obtains the Terrain Coverage and Terrain Cultural Chart Feature data from a non-compliant supplier. This data is classified as data process assurance level 4.

As defined in RTCA/DO-200A, the end user has the ultimate responsibility to ensure the data requirements are met. These responsibilities are satisfied, in part, by obtaining aeronautical data from an RTCA/DO-200A–compliant supplier such as Universal Avionics. By using Universal Avionics-supplied data, the end user agrees to the data quality requirements established by Universal Avionics, a copy of which can be obtained from Universal Avionics upon request. Further, per RTCA/DO-200A, the end user should verify the aeronautical data is current, valid, and appropriate for the intended operation. The end user also should become familiar with applicable notices to airmen (NOTAMs), Jeppesen Database Alerts, NAVBLUE FMS Navdata bulletins, and Universal Avionics Data notices and alerts that may affect operation. Finally, the end user should notify Universal Avionics if it discovers an error or inconsistency in the data.
