A military divert field is a preferred airport having a hard-surfaced runway at least 6000 feet long
(T-1) and facilities for maintenance and/or landing of home base maintenance personnel
(normally restricted to airfields classified as Military; i.e., not P or PVT).
The only requirement for an emergency divert field is a hard-surfaced runway of 4000 feet or
Annotate military diverts with a square (5 NM per side) and emergency diverts with a triangle
(5 NM per side). Each low-level route requires a minimum of two military diverts. All
emergency diverts along the route of flight should be annotated. Also, do not use your
destination as a military or emergency divert.
Under the symbol for each divert field annotate the following:
The field's TACAN or VOR three letter identifier (or nearest TACAN to field).
TACAN channel or VOR frequency (with radial/DME to field if necessary).
Tower or Common Traffic Advisory Frequency (CTAF).
Divert field triangles or squares may be annotated within three NM of planned course.
Figure 2-10 shows some examples of divert field annotations.
