Begging pardons for thread drift here, but how could I ascertain that MVA is 4000 on V264 from that chart?
What sort of clearance would you get if descended to 4000'? It could not be on the airway. I would shoot for a requirement for a clearance "maintain the 073 radial route POM cleared to POM" (or words to that effect) at 4000ft (with an MEA of 6000) and since POM is an IAF I would have thought you would then be OK for the approach?
