instance, only new CHUM since January 2002. Obviously, this option can only help you if the
last CHUM was recorded on the chart you checked out.
WARNING
The CHUM listed on ECHUM doesn't include power lines unless
specific conditions are met. After using ECHUM, you MUST use
the CHUM manual to plot the power lines. These are very
important, especially when chumming hilly areas (a power line can
extend into valleys at the altitude you will be flying).
Additionally, if plotted correctly, they can help immensely in
navigation.
NOTE
Take some time to explore the NIMA homepage. It provides many
services to include imagery that can be very helpful for getting
familiar with run-ins and DZs. Also, two other websites that
students have found helpful are http://www.monkeyplan.com and
http://www.baseops.net. These are private websites tailored to
military pilots.

8.

9.
Be sure the check the ECHUM chart date at the top of the chumming points to ensure the
chart you are using is current.
