pilotsaab:
if we are coming for an approach for a runway which has an elevation of 100feet,and the MSA on the approach plate shows 9500feet,surely we are to descend and land,,my question is ,,arent we crossin the 9500 limit???since msa assures acceptable obstacle clearance of 1000non and 2000mountaineous,,??
MSAs are not operational altitudes in all countries. Unless you know a particular country's rules very well, MSAs should be relegated to "safety orientation" information.
They are not operational altitudes in the U.S., and they provide only 1,000 feet of vertical clearance, even in designated mountainous areas. Further, in U.S. RNAV IAPs they are not sectorized, which makes them of marginal value (at best) in areas with very high terrain in one area.
