Hi,
no wasnīt available then.
I was talking about the regular ones, for home use - as it would not have been physically attached to the airframe (our TIA is mounted on 2 rails bolted to the galley) the discussion was wether a not bolted to the airframe machine would be "installed". We didnīt want to take chances so we opted for the TIA machine. Cessna did not offer enough AC power at the time too, so we we would have to spent a similar amount for the beefed up AC version STC as we did for th e TIA coffee maker...(which is a 28V version)
