FlightPathOBN:
Just curious, but at the IF, the box should have a min 1000'ROC...and if considered mountainous, a 2000' ROC
What box?
In any case, Jeppesen charts don't show obstacle clearance. The parenthetical altitudes are height above the charted runway elevation of 1,675, msl.
I can only speak to TERPs, but initial approach segments in designated mountainous areas (DMAs) require a minimum of 1,000 feet of ROC, not 2,000. Feeder routes and airways in DMAs generally require a minimum ROC of 2,000.
The initial approach segments are governed by the STAR charts for UIII, which state "MEA under radar control."
