The shaded elevation map — Terrain Depiction — and associated software features are designed

to aid pilots by graphically and numerically displaying the approximate elevation of any location on

the map. It is not designed to replace any onboard altitude/elevation instrumentation (i.e. altimeters

or other altitude/elevation measuring devices).Terrain Depiction can be displayed in either the

Vertical or Horizontal display modes.

The “Map Orientation” is set to Track-Up and the Terrain Depiction is set to ON at system start-up,

and can be changed as needed (see below for instructions on how to change the Map Orientation

from Track-Up to Course-Up or North-Up, as well as how to turn OFF the Terrain Depiction Shaded

Land Elevations).

Note

Course Up mode with Terrains (TAWS) is aligned to Track Up behaviour and Map rotation on TRACK UP mode is

made continuously in accord with the HEAD UP RESPONSE setting when in any TERRAIN mode.

3.5.11.1 Terrain “ON”

With the “Terrain” set to ON, the following occurs:

• With Map Orientation set to North-Up and Track-Up, the Terrain Depiction is displayed on all

mapping scales from 1 Nm and above. No Terrain Depiction is displayed with the mapping scale

from1/2 Nm and below.

• With the Map Orientation set to Course-Up, no Terrain

Depiction occurs on any map scale.

Note: Terrain Depiction is disabled at 1/2 mile and below to allow for a normal Track-Up Map

Orientation to be used thus allowing for airport traffic patterns to be displayed on the map.

To turn-on/off the land elevation mapping, follow these steps:

> ‘MENU’ + “TERRAIN” + ‘ENTER’

To change map orientation:

> ‘MENU’ + “MAP ORIENTATION” + ‘ENTER’

With “Terrain” set to OFF, the following occurs: Normal mapping is displayed at all map scales

(without shading).

Determining the Elevation of any area on the map (with “Terrain” turned ON):

The cursor, when moved anywhere on the map, will open up a dialog box that will give the

approximate elevation of that point on the map. Units of measurement default to feet. To switch

to meters, go to MENU.

> ‘MENU’ x3+ “UNITS SETUP” + ‘ENTER’+”ALTITUDE”

3.5.11.2 TAWS

TAWS (Terrain Awareness Warning System), depicts the separation that exists between the terrain

and the airplane.

In order to properly display TAWS, you’ll need to configure the EKP-IV. In MAP mode, press the

MENU key, select TERRAIN and press ENTER. A menu is displayed. Select TAWS and confirm by

pressing ENTER.

Important Note

: After TAWS is enabled; TAWS will not be displayed on the map. You will need to

acquire a position fix. The simulation mode can be used for training purposes. Press the MENU key
