A failed FAA Public ADS-B Performance Report (PAPR) does not necessarily mean your ADS-B equipment is defective. In many cases, the issue is related to system configuration, installation, or data being transmitted incorrectly rather than a hardware failure.

Common causes of a failed or unsatisfactory PAPR include:

  • Incorrect aircraft registration (N-number) or Flight ID
  • Improper ICAO 24-bit aircraft address programming
  • Incorrect aircraft emitter category
  • GPS position source or accuracy issues
  • Transponder or ADS-B software configuration errors
  • Altitude encoder discrepancies
  • Wiring or installation problems
  • Outdated software or firmware
  • Intermittent antenna or RF performance issues

Many of these issues can be corrected without replacing the existing equipment.

Because the PAPR evaluates how your ADS-B Out system actually performed during flight, it is an excellent diagnostic tool for identifying configuration or installation issues that may not be apparent during normal ground testing.

If your report identifies one or more failures, the first step is to have the report reviewed by an experienced avionics technician. In many cases, the issue can be resolved through proper troubleshooting, software updates, or system reconfiguration.

Southeast Aerospace can assist with interpreting PAPR reports, diagnosing ADS-B performance issues, and recommending the most practical corrective action. If a system is approaching obsolescence or no longer cost-effective to maintain, we can also help evaluate modern ADS-B upgrade options that improve both compliance and situational awareness.

After any ADS-B installation, repair, software update, or configuration change, it's a good practice to request a new PAPR following a qualifying flight. Verifying your system's performance before your next trip can help prevent unexpected compliance issues and ensure your equipment is operating as intended.

The FAA's Public ADS-B Performance Report (PAPR) is a free online tool that evaluates how well your aircraft's ADS-B Out system is performing during an actual flight. After a qualifying flight, aircraft owners, operators, or maintenance personnel can request a report that identifies whether the ADS-B installation is transmitting data correctly and meeting FAA performance requirements.

The upgrade of a GTX 335 to the GTX 345 is relatively easy, however is not a “plug-and-play” swap.

The GTX 345 includes integrated ADS-B In capability while the Garmin GTX 335 is ADS-B Out only. 

Both units share a similar form factor in the mounting rack and main connector but upgrading requires:

  • Additional wiring for ADS-B In functionality (the GTX 345 includes an additional connector for this)
  • Integration with other onboard systems such as compatible Garmin displays, MFD, or tablet
  • Possible reconfiguration of existing interfaces or additional interfaces (ex. audio for traffic alerts)

For a detailed assessment of your aircraft and avionics configuration, it’s best to consult with an experienced avionics shop.


In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.
