Non Standard Flight Level
I was cruising across a Terminal Control Area at Flt Level 340 (RVSM) on a NW track and was on direct routing to a point with the radar controller's approval. After a while I was advised by the radar controller to descend to FL 330. I complied and reported "Maintaining FL330 'Non Standard' ". To this the Controller responded "There are no non standard levels in TMA".
Im not clear about this since I was routing via the TMA and was at an RVSM Cruising Level and Yes - under Radar Control. What am I missing here?
