J3 to say that the RPT crew has a higher workload isn't exactly accurate. Remember the VFR pilot is single crew more than likely and can't offload tasks to anyone else on the aircraft.
Frankly I can't see the issue here. Everyone complains about frequency congestion and then thinks there should be clarifying calls for those that aren't familiar with IFR terminology when it is used.
Why would anyone argue against one concise call which EVERYBODY on frequency has been trained to interpret so there is no need for any further calls.
Aiming at the lowest common denominator (ie; student pilot on their first solo) should be the goal so nobody is in any doubt as to what is happening.
Makes complete sense I would have thought.
