1) Aren't they fixed 200 watt radios? Some may be, as far as I know, but I'd doubt very much that all are.

2) ... for the 60 meter band. Having 100 ERP isn't that kind of breaking the rules? Probably would be, but with any antenna that would mount on anything smaller than a battleship, getting 100w ERP on 60 meters would likely take a couple KW from the radio, or maybe a couple dozen KW. Where ya gonna mount a half-wave 60m dipole (100 feet long) on any airplane? Short antennas aren't very efficient, and efficiency is part of the calculation for ERP.
