1. BEARING DISPLAY READOUT - Depending on position of DSPL Switch,
displays bearing programmed for waypoint 1 or waypoint 2.
2. DISPLAY 1-2 SWITCH (DSPL) - Determines information shown on DISTANCE
and BEARING displays: In position 1, distance and bearing programmed for
waypoint 1 are displayed; in position 2, distance and bearing programmed for
waypoint 2 are displayed.
3. FLY/ DISPLAY LAMP - Flashes amber when FLY Switch and DSPL Switch are
not eet to seme number: mmcates that waypoint information being displayed is
not waypoint information being flown.
4. FLY SWITCH - Determines waypoint being used for navigation. In position 1,
waypoint 1 is in use; in position 2, waypoint 2 is in use.
5. DISTANCE DISPLAY READOUT - Depending on position of DSPL Switch,
displays distance programmed for waypoint 1 or waypoint 2.
6. BEARING MINILEVER SWITCHES (4) - Select bearing of desired waypoint
from VOR/DME station. May be used to store bearing of 3rd waypoint.
7. ENROUTE/ APPROACH SWITCH (ENR/ APPR) - Controls width of navigation
corridor. ENR position provides standard (±5 NM) enroute sensitivity; APPR
position provides standard (±1-1/4 NM) approach course sensitivity.
NOTE
Due to unreliable signals, do not operate in the APPR position when
computed distance to waypoint exceeds 51 nautical miles.
8. TRANSFER PUSHBUTTON SWITCH (XFER) - Transfers waypoint distance
and bearing from mini levers into either waypoint 1 or 2 as selected by DSPL
switch position.
9. DISTANCE MINILEVER SWITCHES (4) - Select distance of desired waypoint
