What is the MIA for V18 and South?

MIA is the lowest published altitude on an airway leg that still guarantees obstacle clearance for IFR flight along that segment in the given direction. For V18 heading south, the chart shows 2,700 feet as the MIA for that leg, so flying at 2,700 feet or higher keeps you clear of terrain and obstacles between the charted points. The other numbers aren’t the published minimum for this leg: 2,500 would be too low to guarantee clearance, while 2,900 or 3,000 are higher than the minimum and not the value shown for this segment.
