<description>
|
|
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.

<message>Great job. COMM2 is located immediately below COMM1 in the radio stack, and is tuned in the same way.

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>
