The only catch here is you need to perform the escape maneuver strictly following assigned procedure
Complete to concurr with that.
Between Chile and Bolivia FIR, on the UM688 OTPOP-BOKAP, the MORA is above 180 while the MEA is 125. This gives you a good chance of descending for a depressurization case in this particular area. Otherwise the situation gets tight for many operators.
