NFM Vs. WFM Vs. FM Questions, Please

Hello,



Some questions re NFM vs FM, vs WFM, please:



a. I believe that Police, Fire, Railroads, and "Public Service" now are all on NFM.

True ?



b. But what about Maritime, such as for the C.G. ? Fishing and pleasure boats, etc. the same ?



c. What about Commercial Air ? (do they use any fm at all ?)



d. What about MIL Air ?



Thanks,

Bob
