PFD Navigation Performance Scales (NPS) Indications/FMS-FMC

[manoliar 2]

Flying an IAN approach with 737NGX, (Integrated Approach Navigation) the scale ID annunciation indicates FMS.

The Scale ID should be FMC not FMS.

The possible scale ID annunciations are in FCOM 10.11.14 and there is not such an indication(FMS).

The manual says: FMC - (IAN approach)

Also here is a picture from Boeing:

It is only a typical error in the implementation of 737ngx, (If I am right)  which does not affect the operation of the aircraft but it would be nice to be corrected some time.

 

I would appreciate a comment especially  from PMDG support.

 

Thank you for your attention.

I recommend all bugs be reported on a trouble ticket at PMDG product support, not the user forum, which after validation the bug is entered into a bug tracking system so it's not forgotten.  PMDG Product Support is here: http://support.precisionmanuals.com

Dan thank you for your answer.

I agree with your recommendation, but before submitting a bug I think that it is a good practice to hear some other opposite documented opinions (if there are any). Many times we think that something is a bug when it is not.

So for the next few days the question remains.

Is it a bug or not?

Well, you provided a FCOM reference with information that seems to indicate it is a bug. That's pretty good reason to have PMDG look at it.

I opened a ticket to PMDG and someone from the support team replied:

 

"Hi Emmanuel 

Thanks for the information. I have passed it along to team to look into for any future updates to the NGX. "
