Every instrument pilot should carry one as a backup, and they can also be invaluable for flight schools, FBOs or just for fun. An important question to ask is how you plan to use the radio-will it be a backup, or will it be used every day as a primary communication radio? The answer to that question will determine what features are important to you. Below, we've described some of the important features and terminology you will encounter when choosing a portable aviation radio |
|
| COM vs. NAV/COM: The most basic radios are strictly for communications (COM). However, many radios (NAV/COMs) also offer navigation functions. These radios will receive VOR frequencies and display a course deviation indicator (CDI) with a TO/FROM indicator-just like in an airplane. This feature is a great backup for emergency situations. |
|
| Localizer: In addition to VOR reception, Sporty's SP-200 NAV/COM also receives localizer frequencies and displays a CDI. In an emergency, this feature allows you to fly very precise approaches to many larger airports, even with no electrical system. |
