Aviation Alerts and Advisories

Service Advisory 1865: Display of Information for Facilities Using 8.33 kHz COM Frequencies

PRODUCTS AFFECTED:

All Garmin aviation systems using a Garmin Navigation or Jeppesen NavData database are affected by this advisory.

ISSUE:

The mandate for COM devices to be 8.33 kHz equipped in Europe has recently become effective. Many Garmin avionics pre-date the concept of 8.33 kHz frequencies and therefore older unit software versions do not provide information for facilities using 8.33 kHz spacing from the navigation database.

PILOT ACTION:

No action is necessary. This advisory is intended for informational purposes only. Affected owners may contact their dealer or OEM to determine if updated unit software is available.

RESOLUTION:

Some systems have upgrades available which allow display of information for facilities using 8.33 kHz frequencies. The systems which can display this information are listed in Table 1 (see Service Advisory 1865).

NOTE
Lack of 8.33 kHz frequency information in the database does not prevent the radio from being tuned to the desired frequency.
