CHART CHALLENGE
AERIAL TRAMWAYS AND SKI AREAS
BY MACHTELD SMITH

IF YOU PLAN ON FLYING TO A WINTER OR

summer resort located near hills and
mountains, take a close look at terrain
elevation and manmade obstacles along your
route. Beware if you notice charted ski areas
or aerial tramways as seen here on the world
aeronautical chart (WAC) just south of the
Mount Washington Regional Airport (HIE)
and west of the Pemigewasset Wilderness
Area. If you're tempted to take a closer
look at these phenomena, realize that it is
extremely difficult to see aerial cables and ski
lifts against the sloping terrain. In addition,
pylons supporting the cables may have guy
wires extending outward from them. In this
example, also take note of quickly rising terrain
to the east. Widely spaced terrain contours
represent gentle slopes, while closely spaced

ones represent steep slopes. The Maximum
Elevation Figure (MEF) in the area is 5,600
feet, which represents the highest elevation
within a chart quadrant, including terrain and
other vertical obstacles. The AOPA Air Safety
Institute's Collision Avoidance Safety Advisor
has a section on terrain avoidance. Check it
out for additional details (airsafetyinstitute.
org/safetyadvisors/collisionavoidance).

writer for the Air Safety Institute. She holds a
commercial pilot certificate with multiengine,
instrument, and seaplane ratings.
