Some aircraft, e.g., the Boeing 787 have the option to display a "Mini Navigation Display" on the left Outboard Display Unit, right under the Primary Flight Display:
Is the information shown there a copy of the "normal" Navigation Display on the Inboard Display Unit (possibly with a limited set of information?), or can it be fully customized by the pilot independently of the other ND? (I'm not talking differences between left and right side PFDs/NDs, but I'm talking only one side, e.g. the left side only).
With "copy of normal ND" I specifically mean ALL updates to the ND via the EFIS control panel are reflected on both the ND and the mini ND. This would include wx, airports, range, modes (plan, arc, rose), etc.
In case of independent controls, how can the pilot customize the mini ND?
