    <name>Radio Tuning (PA-18)</name>

    <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 A T I S - 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.
