CHART UPDATING MANUAL (CHUM)
Issued charts are not necessarily up-to-date. The CHUM manual is the best source for new
hazards and obstructions such as recently erected towers and power lines. THE MANUAL IS
THE FINAL WORD in updating charts. The use of such items as E-CHUM is not adequate for
route planning purposes. Inadequate CHUMMING will result in a below average for pre-flight
planning. Students will CHUM all low-level charts within 10NM of course.
MILITARY TRAINING ROUTES AP-1/B
Military training routes are designed to give military aircraft an area in which to practice
navigation procedures. There are several different types of routes, but we are concerned with
two, VR and IR routes. Utilization of these routes enables military aircraft to waive the 250
KIAS airspeed limitation below 10,000 feet in US airspace. To exercise this privilege safely it is
crucial to always squawk the appropriate transponder codes and not exceed the 250 KIAS speed
limit until established on a route.
The routes listed in the AP-1B are the official DOD/FAA approved routes. The route description
includes the following:
Special Operating Procedures
Originating and Scheduling Activities
CHART LAYOUT AND ANNOTATION
Chart preparation will be similar to the standards already set forth in Intermediate and Advanced
Plot the official AP-1/B points on the chart in pencil.
Clearly annotate in black ink the exact AP-1/B points (A, B, C, etc.).
3. Draw the corridor. Look in the special operating procedures to help you determine the
route structure. Do this in pencil as well.
Plot the geographically significant points given below.
