Nav 2000R Modes; Menu Layout Description - Aeroflex NAV 2000R Operation Manual

3.5.1 NAV 2000R MODES

The NAV 2000R local operation is menu driven through the use of mode menu pages. There are six
generator modes and three utility modes. Each top level generator mode menu is accessed by pressing
the corresponding mode menu select key. With the exception of G/S, the LOC/GS key toggles between
LOC and G/S modes. These are aligned vertically and to the right of the display. The main generator
modes are: VOR, LOCalizer (LOC), Glide Slope (G/S), ADF, MarKeR beacon (MKR) and
COMmunications (COM). The utility menu can be accessed by pressing and holding any of the generator
mode select keys, except for the LOC/GS key, for two seconds. Two additional modes, External
Modulation Mode (EMM) and CALibration mode (CAL), are accessible from the utility menu. Also, VOR
and LOC modes have alternate control modes to allow control of their audio composite output signals.
These modes, VORa and LOCa, are accessed by selecting the audio control mode bubble from within
their 1st page. The SELCAL mode is accessed from the SELCAL bubble in PAGE 1 of the COM mode
menus.

3.5.2 MENU LAYOUT DESCRIPTION

Every display menu page can be broken into four different partitions: the Selected Mode Region, the
Status Line Region, the Prompt Line Region, and the Field Entry Region.
On each menu page, there are multiple fields. If more than one page is needed to access all fields of a
given mode, one of the fields will be the next page field.
DISPLAY REGION: Selected Mode Display
The Mode Select region is located in the upper left-hand corner of the display. This region indicates the
NAV 2000R current mode of operation. Distinguishing it from the other regions, the selected mode region
is displayed using inverse video. The character assignments for each mode are:
