According to the most recent data from the FAA (Federal Aviation Association), slightly fewer than 10% of all U.S. registered ADS-B (Automatic Dependent Surveillance Broadcast)-equipped aircraft are NPE, or non-performing emitters. Having NPE means the aircraft’s ADS-B Out system is not transmitting in compliance with FAR (Federal Aviation Regulations) 91.227.
Here are some common issues that result in having NPE:
- Incorrect software version or improper system configuration can result in reduced aircraft position integrity/accuracy.
- Incorrect emitter category results when the aircraft’s ADS-B system is transmitting the wrong emitter category based on its maximum take-off weight.
- Incorrect Flight ID is a result of the aircraft registration for Mode S not matching the Flight ID.
- Transmitting airborne data while the aircraft is on the ground.
Is Your ADS-B Equipment Compliant?
Go to FAA Website: https://adsbperformance.faa.gov/PAPRRequest.aspx and request a PAPR (Public ADS-B Performance Report). A PAPR provides an additional method of verifying proper operation of ADS-B equipment.
After answering a few questions about your ADS-B installation, you will receive a report from the FAA showing what parameters have failed, if any. Instructions and a User’s Guide can be found on the website.
If you have not complied with the upcoming FAA ADS-B mandate, the time is now. For more information, go to: www.DuncanAviation.aero/adsb
