Narrative:

We were sitting on the ramp; immediately adjacent to the [local] flight school. It was a cold; fairly low IFR day so we were expecting to enter icing conditions immediately after takeoff. With the brakes locked; we started to add power to test the anti-ice/deice systems. Then we realized we were still on a very tight ramp; with small fixed-wing aircraft on the ramp behind us parked with their tail to our tail. We brought the power back to idle; however the jet blast may have caused damage to one or more of the small trainer aircraft parked behind us. In the future; we will ensure there is nothing behind us when increasing power above idle; and we will be moving our operations at this airport to a location that is well separated from the flight school's fleet of trainer aircraft.
