FAA AC 20-153A Type 2 LOA Status

Universal Avionics holds a current Type 2 Letter of Acceptance (LOA) from the Federal Aviation Administration (FAA). This LOA indicates Universal’s navigation database processes for Flight Management Systems (FMSs) with software control number (SCN) 601.x/701.x and later are compliant with RTCA DO-200A/ED-76, Standards for Processing Aeronautical Data and FAA Advisory Circular (AC) 20-153A, Acceptance of Aeronautical Data Processes and Associated Databases.

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

Jeppesen is the holder of a current Type 1 LOA from both the FAA and the European Aviation Safety Agency (EASA).

Navtech is the holder of a current Type 1 LOA from EASA.

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.

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 navigation data from an RTCA/DO-200A–compliant supplier such as Universal Avionics. By using Universal Avionics navigation 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 navigation data is current, valid, and appropriate for the intended operation. The end user also should become familiar with applicable notices to airmen (NOTAMs), Jeppesen Navigation Database Alerts, NAVBLUE FMS Navdata bulletins, and Universal Avionics Navigation 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.
