Possibly a naive question but how would we go about creating and publishing (via Air Services and thus AvPlan and OzRunways etc) an authorised LNAV or LNAV/VNAV approach at a busy ALA where there are currently no navaids?
Obviously there are criteria for waypoint placement with regards to splays and to obstacle clearance but that’s not a difficult task. Being a simple Lat/Long position rather than a navaid means there’s no major expense involved but no doubt being related to aviation there will be some process involved which will make it an expensive and time consuming exercise!
However if it’s a straightforward process it would greatly increase the all-weather viability of this and other airports. Guess it can’t be that easy as airports across the country would no doubt have done it well before this time.
