I received the corrected replacement wire harness, installed it and flew yesterday.
With the initially supplied harness my ads-b performance report indicated all good (zero failures) except in 2 categories:
Baro Alt 100% failure
Mode 3A 100% failure
The new ads-b performance report indicates all good except:
Baro Alt 1.44% failure
The FAA ads-b performance report comes with the advisory:
Be advised that flight operations occurring at the fringe of ADS-B ground station coverage (refer to the FAA ADS-B Coverage Map) can cause intermittent signal losses with aircraft avionics. This condition may generate various false failure indications (red flag for Percent Failure - PF and/or Maximum Consecutive Failure - MCF flag) within a Public ADS-B Performance Report (PAPR). Such failures will vary depending on the duration of the flight in this condition. If you receive a PAPR with suspected false failure indications, please email [email protected] and request that your avionics performance be manually reviewed prior to taking maintenance action. Please attach the PAPR file and include (PAPR Review Request) in the subject line of the reply email to help expedite a response.
Recipients of Performance Reports flagged red for Air-on-Ground issues are advised to contact their repair shop and/or avionics manufacturer(s) for guidance on appropriate corrective action.
Perhaps the small percentage of Baro Alt failures we are seeing is related to ads-b coverage and not the installed device?
