I would never improvise a 3 degree path below MEA. That is contrary to all the efforts we made in the U.S. after TWA 514.

I would file and insist on routing over PXM V1 HUX.

I have just looked at the charts. I find it unbelievable that the airport doesn't have STARS to make a safe descent onto the approaches. The only relief is a 13,400 MSA arriving from NUDOS. That...

It would look the same except with the EFB version you can zoom in.

A Part 121 operator wouldn't be carrying expired charts. In any case, this particular procedure hasn't been changed for years.

The controller didn't direct them to descend. He cleared them for the VOR/DME-C to cross CEGAN at, or above, 7,800. The crew should have "wrote off" that "at or above" either as quirky or accepted...

Why couldn't the hypothetical Navajo pilot make the same decision to accept the clearance to 7,800? In such case, there would likely be no on-board TAWS to make the save.
