    The manual says on page 166:

    The time to completion of alignment is known as ‘time to NAV’ mode (TTN).
    TTN can be seen on the IRS sub-section of the NMS or FMS.
    

    Where can I find this IRS sub-section? The FMS manual makes no reference to this section??

      Thanks for raising this. The IRS sub-section of the FMS is not simulated in the RJ Professional, so we will update the manual in the next RJ Professional update to reflect this.

      The current 'time to NAV' (TTN) can be viewed in the simulator by hovering over the IRS alignment knobs with tooltips enabled.

        The current version of the manual still mentions the TTN indicator in the FMS. I spent a good amount of time looking for it before I founds this post.

        ...There's got to be a better way than enabling tool tips lol. How about somewhere in the EFB?

          The TTN section was updated in the latest version of the manual. Could you kindly double-check that you've downloaded the latest version from here: https://support.justflight.com/support/solutions/articles/17000142841-rj-professional-msfs-manuals
