box at the bottom of the screen says "Extend" next to the runway name.

(As long as we have sufficient information about it in our database, Air-

Map can display a runway extension for any runway.) Press

unit will ask "Do you want to setup Runway Guidance?" Press → to

NO|ENT. The runways screen will go away, returning you to the airport

information screen. Now you can press

tension on the map.

Runway guidance selection message.

Runway extensions are meant to serve as visual references to help you

orient the plane as you approach an airport for a landing. The exten-

sion appears as a fan-shape, with its tip pointing directly to the touch-

down zone or threshold of the runway you're approaching. This allows

you to navigate toward the wider end of the fan, so once you turn down

the extension you can easily judge how far you've got to touch-down.

To turn off an airport extension, press

MENU|↓ to CLEAR RUNWAY

EXT|ENT|EXIT.

Runway Approach Guidance feature

The AirMap also uses the Runway Extension command to extend a lo-

calizer-type display to the landing runway; we call it the Runway Ap-

proach Guidance feature. After selecting a runway extension (see in-

structions at the bottom of the previous page) the unit will ask "Do you

want to setup Runway Guidance?"(See the previous image.) If you want

the AirMap to navigate a localizer-type approach select

YES and press

ENT.(Select NO if you want to continue your own navigation with a regu-

lar runway extension.)

When you select Runway Guidance, the unit will display a localizer-

type fan and create a route automatically for guidance down the run-

way's extended centerline. Once selected, however, you are no longer

navigating your earlier route, because the AirMap assumes you are on

radar vectors or your own vectors to intercept final.

The HSI and all other CDI displays will now be set to the inbound run-

way course and will give guidance to left or right of centerline via the
