[Land-speed] non-LSR aircraft AC frequency

[Rich Fox]

When I retired and I bet still today, The galley equipment was 400 cycle 
110. Every so once in a while I would have to make a modification to the 
coffee maker test stand. They would not shut down the whole stand so I could 
work on one part of it. Usually I would get bit. Wakes you right up.  RF
