The National Business Aviation Association (NBAA) is awaiting a new solution from Rockwell Collins that will rectify previous issues with the software database of instrument approaches. NBAA said it and other industry stakeholders were told by Rockwell Collins to expect the solution Thursday.
More than 10,000 instrument approaches should be restored to the software database with the new solution, NBAA said. These approaches were removed due to software issues affecting low temperature environments and manual altitude entries during missed approaches.
According to NBAA, Rockwell Collins advised that restored approaches are fully usable with the following limitations:
"Operators should not use software-based temperature compensation for low temperature approaches. Instead, Rockwell Collins will advise operators to follow established FAA and International Civil Aviation Organization procedures for manual compensation during low temperatures.
"Operators should not manually edit missed approach altitudes."
NBAA said that operators should review the database for particular approaches, as there may be other changes that are included as a result of other factors not covered by temperature compensation or manual altitude entries.
