just I have never seen 'LR' on a chart - maybe I'm too sheltered, Mil, Aerad and Jepps
Sheltered indeed! Been on our AIP charts for a couple of decades here.
Even more shocking... there's an "LB" on that chart Agent 86 linked to in post 4!
Then again, we've had Distance/Altitude profiles on our charts for about the same time, with the rest of you only now catching up.
