As
normal....read the question carefully.....
do they want GRID MINIMUM OFF-ROUTE ALTITUDE - in this case the higher of
2700ft and 3200ft
or do they want MINIMUM ENROUTE ALTITUDE - the altitude or FL marked on the
airway
or do they want MINIMUM OFF-ROUTE ALTITUDE - the altitude with an 'a' after it
on the airway.......etc etc.
Definitions of these altitudes can be found in the CHART GLOSSARY at the front
of the JEPP MANUAL, and also page 57 of the ENROUTE CHART LEGEND is useful.
