RNAV routes 3



From the airplane point of view, the navigation system defaults/changes to 1 NM integrity levels within 30 NM of your destination. Entering a TMA that is not within 30 NM of the destination airport will not affect the integrity level used by the avionics.
So, from the airplane point of view, I believe Ian's response is correct.
