Preface

Low/medium frequency colored airways are a rarity outside of Alaska, but there a couple still around. What does the color (red, blue, green and amber) tell you about the airway?

1.

The strength of the navaids used along the route.

2.

The color of the flashing beacons used to identify the route on the ground.

3.

The general direction of the route.

4.

Nothing - the feds just wanted to make the enroute charts a little more artistic.
