INFORMATION Page is used to save the GDL
69(A) activation data when the XM services
are initially set up. It is not used during normal
operation of the GDL 69(A), but it should have no
adverse effects if inadvertently selected during
flight. Refer to the GDL 69/69A XM Satellite
Radio Activation Instructions (190-00355-04, Rev
E or later) for further information.
Weather Product Age
The age for each of the enabled products is displayed
on the right side of the display. Times are based on GMT
time when the data was assembled on the ground, not the
time the data was received by the XM receiver. When the
age of a weather product has exceeded half of the expiration
time, the product time changes from light blue to amber in
color.
