TRSAs exist in Class D and Class E airspace, but are not a type of
controlled airspace.

So then is it correct, that if the TRSA controller issues an
instruction to you as a participatory flight, you are only obliged to
follow that instruction if you choose? Or are participating flights
required to follow TRSA controllers' instructions or cancel Stage
Three participation?
