Negative, the 'briefing' wasn't the problem, not understanding the automatics and actually flying the airplane most certainly was.
Negative. If not for the terrain -
not understanding the automatics and actually flying the airplane, would have been a little embarrassing but ultimately of little consequence. The crew are
always responsible for terrain clearance, not ATC and had they been more situationaly aware of the surrounding terrain the crew would never have allowed that descending left turn while within the valley and below the level of the surrounding peaks. This counts double in a non radar environment such as the arrival into Cali. A comprehensive briefing of the descent and arrival would have highlighted the presence of the high terrain and the fact that all roads to CALI from the North pass 1st through TULUA VOR
not ROZO.
Here's a little clue I can share. If you are ever unsure for whatever reason, where the magenta line is going to take you when plugging in a new waypoint. Put the nav in HDG mode on the original course before making the new waypoint active. That way you get to see a preview of where the nav want's to go and you can decide whether that looks right before committing yourself. Failing that, allways have the heading bug shadow your current course when in NAV mode and if the NAV takes you off in an unexpected direction when plugging in a new waypoint, simply enter HDG mode to resume the original course until you can sort it out.
Regards, no charge.
