Certain air-resets may have greater potential to negatively effect sub-systems than a ground reset would. Any time i do an Air reset I want to be talking to a guy on the ground that is monitoring the AirCraft systems and has access to a great deal of tech data during this time. Just like most computer glitchs, an Air reset may not go as planned.
Granted their are probably some that a fairly simple Air resets, however, the complx ones may really be annoying when the things go south.
