What license do I need to transmit on an aviation radio?
<p>I've asked <a href="https://aviation.stackexchange.com/questions/83453/which-fcc-license-do-i-need-to-operate-an-aviation-radio-on-the-ground">this question</a> over on <a href="https://aviation.stackexchange.com/">Aviation Stack Exchange</a>, but nobody over there knew the answer, so I thought I'd ask here.</p>
<p>I'm a student pilot. I know that my pilot's license also acts as permission to use the radio in an airplane. But, I recently purchased a handheld airband radio as a backup to the plane's radio. If I wanted to use my handheld on the ground, not in a plane, what license would I need? Is this even possible?</p>
<p>(I already have a Restricted Radiotelephone license, if that helps.)</p>
<p>(No, I don't know <em>why</em> I would want to do so. I just like having my options open.)</p>

<p>The possible types of ground stations that could be licensed by the FAA are outlined in the <a href="https://www.fcc.gov/wireless/bureau-divisions/mobility-division/aviation-radio-services/ground-stations" rel="nofollow noreferrer">Ground Stations</a> website. Those listed are</p>
<ul>
<li>Aeronautical advisory stations</li>
<li>Aeronautical multicom stations Aeronautical enroute stations</li>
<li>Flight test stations</li>
<li>Aviation support stations</li>
<li>Airport control tower stations</li>
<li>Automatic weather observation stations</li>
<li>Various radio navigation stations, such as omin-directional range stations (VOR)</li>
</ul>
<p>Other types of authorization may exist, which I have not found detailed information for. Such authorizations could be a blanket authorization to use a radio in an emergency, or use by military and Civil Air Patrol stations under authority emanating from the <a href="https://www.ntia.doc.gov/" rel="nofollow noreferrer">National Telecommunications and Information Administration</a>.</p>
