(2021) Service Advisory 20132 Rev C: Distance To DME

REVISION C:

Updated Resolution

PRODUCTS AFFECTED:

All GI 275 products with software versions 2.21 and earlier, with an HSI page and interfaced to a GTN or GNS series unit are affected.

ISSUE:

When the localizer is tuned and a GPS flight plan is loaded, the GI 275 provides a distance to the tuned localizer station. It does not provide a distance to the DME station.

ACTION:

For DME distance, use a receiver capable of providing DME station distances. If the aircraft is not equipped with a DME receiver, use the GPS waypoint distance provided by the navigator.

RESOLUTION:

This has been fixed in GI 275 Software Version 2.32.
