Users of Garmin GNS gear need to be aware of this!
TO: Owners/Operators of GNS 4XX/5XX (WAAS and non-WAAS) units and Garmin Integrated Flight Deck Systems
DATE: 11 February 2010
SUBJECT: DME Arc Legs Computed Incorrectly
AFFECTED PRODUCTS: All Garmin GNS 4XX/5XX (GNS 480 is not affected) units with operating software v2.07 and newer, all GNS 4XXW/5XXW (WAAS) units; and all G900X, G950, G1000, Perspective™, and Prodigy™ Integrated Flight Decks.
DESCRIPTION: A small number of DME arc transitions in the navigation database (all outside of the U.S.) are incorrectly computed/displayed when the approach is activated. This results in an erroneous point-to-point flight path instead of an arc flight path, or in some cases, the arc flight path leg is absent.
PILOT ACTION: Do not fly the listed approach procedures (Table 1) using GPS navigation when operating with any Navigation Database prior to Cycle 1003.
RESOLUTION: The approaches that cause the erroneous DME arc transitions will be removed from Cycle 1003 and future cycles of the Navigation Database until the issue is resolved.
