Most EFIS Navigation Display systems contain a few different modes. These can each exist in two forms (except for the plan mode), Full Rose and Expanded. Full Rose displays show a full HSI on screen so data can be presented in all directions from the aircraft, such as bearing pointers and CDIs for VORs and ILSs, etc.

Expanded displays show just the area ahead of the aircraft (and about 45º either side of the heading) with often less clutter and a more useful view of forward waypoints, etc, useful in the cruise.

The 3 modes which have both functions are MAP (showing the planned route ahead, waypoints, beacons, etc.), VOR (giving standard VOR HSI information) and APP (which gives a wider view of the localiser and glide path pointers).

The "PLAN" mode is the odd one out, and shows a North Up view of the planned route.

Figure 1 shows an expanded approach (APP) mode display, as there is an "ILS" in the bottom left corner, and both the localiser and glide path indicators are showing, with not much else on the main display.

Figure 2 is a PLAN mode display, showing a North Up view of the route.

Figure 3 is an expanded MAP mode display, as the route ahead is shown, with LNAV and VNAV indicators showing .

Figure 4 is an expanded VOR display, as there is a "VOR" in the bottom left, and there is no glide path indicator on the right.
