Nice does not nothing about Bizjets, at all... If something is in service at Kilo, i bet it will 400Hz, and an Air Con nozzle that will fit an Airbus..
Running 28v along taxiways and such, taking into consideration the various location of GPU sockets is an engineering monster in itself, plus the quasi non-existence of Air con external plugs on GA airplanes. I see it as a good laugh next time a very well trained yellow man ( plus the inevitable blue men AKA gendarmerie) will try to use these devices.
Please , NICE, prove me wrong !!!!
