What you cannot do on the IMCR is fly in Class A (IFR).
Hence why creating user way points is more needed flying OCAS than flying in CAS.
Flying OCAS means avoiding CAS, means flying to points which wont have VOR, NDB, intersections in the correct places.
Flying OCAS Means you will be shooting approaches into places which may have zero published approaches or limited approaches which maybe pilot interpretated or non precision.
Hence the reason why I am pushing the knowledge of creating user waypoints in a safe and accurate way and backing them up by checking them.
Infact using a Garmin will allow you to create a user point simply by placing a cursor where visually you want it to be and allowing the system to create that point for you?
