F-14B ACLS Localizer needle not aliening to the center during approach

[Hollister56]

Has anyone done a F-14B ACLS recently and have the localizer needle off to the right during the approach.  I do , and It lands on the centerline with the needle off to the right.  The F-18 ACLS localizer is centered when I fly that jet.  I believe all the switches are in the correct position and I've tried switching them, but the localizer needle is to the right.  I set the course to the final bearing given from carrier air traffic control.

Any suggestions are welcome.

Thanks, Ed

You've made the datalink to the wrong carrier?  Easily done amongst a big taskforce.

Afaik ICLS antennas can't be reliable very close to the landing area at least for azimuth^*. From around 3/4 mile you should lineup visually. ACLS probably has some corrections built in for that. Now the question what have you set on control panel?

You can select either ACL or ILS for the HUD and VDI to display.

Then ACLS would fly to the carrier it was coupled with, right? Or you'd be out of linup to even couple ACLS.

Edit: ^*There are two separate antennas for ICLS AN/SPN-41 - one for azimuth, centerline, below the ramp on the stern and the other for elevation, elevated on the island, where there's also AN/SPN-46 ACLS antenna located.
