dresoccer4 Posted January 24 Posted January 24 I have IRS align set to FAST on the EFB. However it's been over 5 minutes and and the PFD and MFD still say not aligned. i've attached images for reference. any help?
ual763 Posted January 24 Posted January 24 (edited) Well, your ECAM does not say IRS IN ALIGN, are you sure you actually hit the ALIGN IRS prompt in the CDU? Edited January 24 by ual763 Robert Schumacher

ual763 Posted January 24 Posted January 24 Well, the PRIMARY GPS Lost message will be on there naturally as an advisory after it being lost before power was applied. It is an advisory and is to be canceled. The AFCS displays will be blank until the pitch trims switches are on and the pitch trim switches won’t stay on until the IRS is aligned. So, this all leads to you not selecting the ALIGN IRS prompt on the INIT-A page of the FMS/CDU. Robert Schumacher
ual763 Posted January 24 Posted January 24 I see in your latest photo, the FMC is also prompting you to select the ALIGN IRS prompt. Robert Schumacher

dresoccer4 Posted January 24 Author Posted January 24 UPDATE: it finally worked. I even had irs align on instant, however it took several minutes. good to know 1
ual763 Posted January 24 Posted January 24 Just to be clear, you clicked the prompt on the INIT page? Robert Schumacher

Deleted Account Posted January 25 Posted January 25 So what seemed to be the issue then? With the setting on fast, my A300 aligns itself within 3ish minutes. Did you by chance change the setting after starting the alignment? Cause in that case it will still take the previous selected value into consideration.

I'm not 100% what both the issue and the fix seemed to be. I did try to change the alignment time mid-alignment but as you mentioned it didn't react to that. I think a combination of flipping IRS switches multiple times, not pressing the align button on the fms in a timely manner, and changing the align time on the efb. One or more of these ended up fixing it after some time. I'm sure it was user error. I'll try a fresh flight again soon and see if I can get it to work normally.
