Extremely unlikely to go away. Dispatchers are in CASS, it’s in the FAR’s, and if there is one thing I have noticed about the FAA in my 25+ years of dispatching, it’s that they are very opposed to fast change. If it ever were proposed, there would be tons of advanced warning...and I don’t really see it being proposed to be honest. It is beneficial to our jobs, and the number of working dispatchers at part 121 airlines isn’t large enough that it adds any sort of “strain” to the system.
