Service Alert 1420: Standby Navigation Database

PRODUCTS AFFECTED:

  • G900X, G950, G1000, Cirrus Perspective, and Embraer Prodigy systems with GDU software versions 13.00 through 13.06, 14.00, and 14.01.
  • G2000, G3000, G5000, and Embraer Prodigy Touch with GDU software versions 3.00 through 3.18 and 4.00 through 4.10.

ISSUE:

Using the standby navigation database feature may result in the absence of navigation information when the standby navigation database is transferred to the active database.

Until system power is cycled again (after the standby to active database transfer), navigation information may be absent and the HSI (Horizontal Situation Indicator) displays a “T” (normally indicates True North) following the HSI digital heading readout when True North is not selected.

PILOT ACTION:

Only load navigation databases as an active navigation database. Whenever the “NAV DB UPDATED – Active navigation database updated” message is displayed, cycle system power (while on the ground).
