Make sure you arrive with LOTS of FUEL!
They have the charming habit of closing an airport without notice for a full hour around the time of a 'VIP' departure. This VIP could anything from el presidente down to some rural chief, or his wife.
Besides that the approach aids (such as they are) go off with regularity, as do the lights!
Be prepared for the worst...as Ernie Gann said...'Always have an out in your back pocket'.
