Pilots operate under a Class Licence, which is set out in detail
here.
Seems like your situation fits the "aeronautical mobile station" definition - so if you have a FROL you should be OK, provided you identify yourself "using a form of identification that clearly identifies the station". I guess that's the same rule our instructors operate under when they send us solo and keep in touch on the handheld transceiver.
There are confusing frequency limitations, but seems if it's mentioned in AIP it's OK!
