|
|
Radios are used both for communication, and also for navigation.
|
||
|
|
|
||
|
|
This tutorial will teach you how to tune the radio of the aircraft to pick up
|
||
|
|
the ATIS - Automatic Terminal Information Service. This is broadcast by all
|
||
|
|
but the smallest airports and provides information on the current ground-level
|
||
|
|
weather, the altimeter setting and the runway in use.

The NAV radios work in exactly the same way, except they use a different frequency

range, and their output goes to the navigational instruments.</message>
