OROCAs for direct random RNAV routes
Asked by: Drew 4533 views Airspace, Instrument Rating, Student Pilot
"OROCAs depicted on NACO en route charts do not provide you with an acceptable altitude for terrain and obstruction clearance for the purposes of off-route, random RNAV direct flights in either controlled or uncontrolled airspace. OACRAs are not subject to the same scrutiny as MEAs, MVAs, MOCAs, and other minimum IFR altitdues." (Instrument Flying Handbook 3-28)
So, if OROCAs are not good enough altitudes to fly for obstacle clearance when flying random RNAV direct flights, then what is?
