Chapter 9

Nearby Landings

It is possible to define waypoints as

Landing

, allowing the pilot to quickly check for landing options.

The Near Landings page will show all the waypoints (defined as

Landings

) for which the necessary

glide ratio is finite. Additionally for each waypoint the distance and glide ratio is also shown, this
list is sorted by glide ratio in ascending order (see Figure

9.1

).

The near landings page can be accessed directly from the Flight Mode screen, by using a short

cut function key (see section Section

13.14

).

In order to define a waypoint as a landing the

Landing

parameter should be set to

Yes

in the

waypoint edit screen (see Section

5.1.3

).

The Near Landings page can be used to make a

Go To

by using the UP, and DOWN buttons

to select the desired waypoint. Pushing the ENTER button will immediately activate navigation
to the selected waypoint.

On the example of Figure

9.1

the closest airfield is 12.48 Km from our present location, and the

necessary glide ratio to reach it is 9.6.
