A Cessna A150L is an “Aerobat” not a “Commuter.” Even a regular 150L would not necessarily be a Commuter as the Commuter, Trainer and Standard were marketing designations for different equipment packages. The A150s and A152s were structurally different from regular 150s and 152s (with the same suffix letters) in order to be stressed for mild aerobatics, hence Aerobat. Our A150L is N6438F and we use the Aerobat callsign when communicating with ATC.
Unfortunately we have to pick one name to best represent the entire C150 fleet. We could change it to “Cessna 150” if you don’t think “Cessna Commuter” represents the fleet very well.
What brought this up? If it’s what I think it is, don’t get in a hissy fit but go see these topics instead: discussions.flightaware.com/view … raft+codes
Really 
I don’t know what to say, I always just said “Cessna 12345.” Until I got up to a 210, then I said Centurion. Even twin Cessna’s were just “twin Cessna.” I did call a 421 a “Golden Eagle.”
