Active AIRAC Cycle on CDU

[GDR]

Hi,

I'm new on this, but I'am subscribed to the Navigraph AIRAC cycles.
When I perform an update of the CDU AIRAC, no problems occur.

When I startup the CDU I can see the new AIRAC.

Example,

I've just downloaded the 0906 cycle.
On the display I get the following:

ACTIVE
MAY7JUN3/09

JUN3JUL1/09

I can change the periods, so that JUN3JUL1/09 becomes the active one. But the PM CDU doesn't keep this in memory the next time I start the CDU.

How can I resolve this?

AIRAC cycles are being updated everey 28 days.

MAY7JUN3/09

JUN3JUL1/09

means that this cycle is valid from MAY7JUN3/09 through JUN3JUL1/09. Thas is what the CDU displays. You can only have on AIRAC cycle stored in the CDU. There is no way to select between to different cycles by the LSKs.
