Re the GPS and "legal requirement in controlled airspace".
I seem to recall from years back that transit of Egypt required a light aircraft or helicopter to follow airways at a quite ridiculous level, FL120 or so - probably due to the military state's paranoia VFR was either not recognised or was not allowed at low level.
It could well be that states with regs as restrictive as this might require a GPS in order to follow the airway - so TCT's statement about GPS being required may, once again, contain a localised nub of truth.
