I completely agree with the general points, but was dealing primarily with the example quoted and in particular with the expressed difficulty
How does one find ADIDI or DIRGO?
The problems raised in post #1 are very familiar at 'regional' (and some international airports) in Canada and do require some serious thought to operate non-RNAV.
The DIN example is so simple - and there is NO terrain, and indeed it is operable 'non'-ATC' also, and locating those points should be 'child's play'..
