Legality of APRS
As you might expect, this is a question that has arisen many times about APRS. Some old hams have even taken the position that APRS is absolutely forbidden to use in the ham radio service at all ( they are generally insane...)
The FCC rules require the operator of a station to have a "Control Operator". The operator need not be physically
present at the location of the transmitter, but he must remain in
control of the station. These terms are not exhaustively defined, but there is no question in the FCC's mind, that a tracking transmitter on a hunting dog does not require the dog to have a license, only that the licensee have control ( the ability to turn on and turn off) the tracker. The same goes for balloons, satellites, etc. Repeater operators don't have to camp out on the mountaintop to be legal.
I have people fly test my gear in various ways all the time, with my call sign, and I remain the control operator, since the device is switched on (or "caused" to be switched on by me.
The way you phrased your question makes it appear that you basically want to borrow a ham license, which would not be permissible or legal. If the Control Operator places a tracker in your aircraft and turns it on, that's okay. If he give you a tracker and under his guidance you turn it on, and under his direction you turn it off, that's semi-okay too but pushing the envelope. (Hams without hands do this all the time, and I have never seen one doing the Perp-roll in his wheelchair out of Federal Court for unlawful operation.
Reading part 97 in its entirety can help make this clear, but it may also make your head explode, since you will have to differentiate between Stations, remotely controlled stations, Telemetry stations, Beacon Stations, etc. The APRS Wiki has done a good job of explaining the Control Operator situation and I have spoken with past head of enforcement for the FCC to validate the positions therein:
