LOW-LEVEL AND TACTICAL FORMATION
5.
Use the Chart Updating Manual (CHUM) information to update obstacles on your chart.
6.
Locate the drop zone or landing zone, select the initial point (IP), turnpoints, and
checkpoints.
7.
Draw course lines using radius of turn over turnpoints.
8.
Use common chart symbology.
9.
Determine headings, minimum and maximum altitudes, and times.
10.
Compute groundspeed for each leg.
11.
Calculate continuation fuels for each turnpoint.
12.
Determine the route to the entry and exit points.
13.
Complete DD Form 175 (if required).
14. Obtain final weather brief and DD form 175-1. Analyze final LL winds and make any
required corrections.
15.
Perform the mission brief, do a route study, and review emergency procedures.
16.
Fly the mission.
17.
Debrief the mission.
Choose an MTR. AP/1B provides textual and graphic descriptions and operating instructions
for all MTRs. Three maps, covering the western, eastern, and central US, depict each low-level
MTR. These maps provide some specific information pertinent to each route (length of route,
direction of flight on the route, entry points, alternate entry and exit points, altitudes, etc.).
When using MTR charts, make sure you know how to correctly identify entry and exit points.
Common errors include incorrectly plotted coordinates and ignored restrictions (airports to
avoid, radio calls to make, etc.). Finally, you should know what the confines of the route are
(top, bottom, and lateral) so you can avoid unacceptable deviations. AP/1B breaks low-level
MTRs into three main types: IR, VR, and SR Routes.
1.
IR Routes. IFR Military Training Routes (IR) must be conducted on IFR flight plans
regardless of weather conditions. Your flight plan must have the entry fix (radial and distance),
route designator, and the exit fix (radial and distance). You must enter and exit the route via
published entry and exit points or published alternate entry and exit points, and you must have a
specific ATC clearance prior to entering or exiting the route. Once on the route, you must
remain within the published route corridor (width and altitude). When practical, avoid flight
within 1500 feet AGL or 3 NM of airports. While AP/1B allows IR routes to be flown in IMC, it
also gives strong cautions when doing so.
