Chelton Flight Systems this month expects to issue a software revision to operators flying with the company’s FlightLogic synthetic-vision EFIS to fix a known anomaly that the FAA has said could provide misleading guidance under certain circumstances.

Chelton has issued a pair of Service Bulletins (150-045972 Rev. A and 150-045973 Rev. A) to fix the software discrepancies, which mainly affect instrument approach procedures with climb requirements of greater than 300 feet per nautical mile.
