WXR and Xponder clarifications

[goggi 9]

Hello,
just two clarifications on the NGX, please, I am unsure whether the following two issues are normal:

1- The WXR test pattern is missing. During radar test, ND labels and voice announcements are OK, but no pattern is displayed after them.
This was checked under various conditions (DC and AC On, EFIS WXR button On, no other WXR function active, then each function selected in turn).
WXR works perfectly with Active Sky.

2- When Xponder is set to TA/RA, ND displays TA ONLY (as for the TA Only position).

Thank you for your help,
Giorgio

Unsure of this one. I'd need to see it in the sim.

It will display this in certain conditions (on ground, on final, etc). It automatically sets this so that two transponders won't try to negotiate a solution that's unworkable (a plane on final can't maneuver very quickly, or descend away; a plane on the ground really isn't in the position to climb or descend to get away, etc.).
