How is that a regressive policy? Have they allowed that operation in the past and they are now regressively retracting it?
Not sure what you mean by "that operation." The overuse of RNP AR for non-terrain-related purposes is quite exclusionary. The "green" objectives could be far better served by using non-AR advanced RNAV with unrestricted use of RF legs by all aircraft equipped with modern avionics.
How is this this an unfair policy toward business operators?
When the RNP AR IAPs become the preferred method of access to busy airports, the non-AR aircraft will go to the holding pattern.
It seems to me that RNP started out as a way for Alaska Airlines to get into Juneau and Sitka more often. Now it's a "Greenie" method to trash BizAv?
Exactly. The way Alaska Airlines uses RNP AR is only when conventional procedures are limited by terrain. Now, however, other airline operators have chosen a method that requires equippage they have, but most non-air carrier aircraft do not have. The result is not because of a deliberate plan of exclusion, rather it is a plan that only considers the equippage that some airlines happen to have and one operator chose to spend a fortune to upgrade, now they are forcing the overuse of RNP AR to become national aviation environmental policy.
