PRACTICE ORDNANCE
TYPES OF ORDNANCE
In the Training Command, you will use two types of practice ordnance: the Mark 76 (Mk 76) practice
bomb and, if available, the 2.75" FFAR. Practice ordnance consists of water-sand fills that simulate
the ballistics of general-purpose bombs. Practice ordnance possesses the same delivery character-
istics as more sophisticated weapons. Training Command ordnance simulates combat ordnance
and is more than adequate to prepare you for advanced ordnance and delivery methods. The Mk 76
simulates a Mk 82 (500 lb.) bomb, and 2.75" rockets have been used in combat with a variety of
warheads.
PREFLIGHT INSPECTION OF ORDNANCE
Careful preflight inspection of your ordnance load will help to ensure a safe and successful flight.
Use the following procedures to preflight each type of ordnance you carry in the Training Command.
BOMBS
1.
Check Master Armament switch in SAFE (Figure 5).
2.
Check that the weight on wheels bypass switch lever is locked to WEIGHT ON WHEELS
position (located in the nose wheel well).
3.
Check security of the practice multiple bomb rack (PMBR) to station with safety pin installed
from right-hand side.
4.
Check electrical cable (pigtail) and cannon plug secure from pylon to PMBR (Figure 3).
5.
Check each bomb for security to PMBR. You may grasp each bomb by nose and tail and
cautiously check for movement; slight movement should be evident. Too much play indicates
improperly attached ordnance; a bomb with no movement at all may not drop when you release
it at the target. If you are in doubt, call an ordnanceman. Do not attempt readjustment
yourself.
6.
At the rear of the PMBR, check the station selector on SAFE (Figure 3).
7.
Check the nose of each bomb for a smoke charge secured by a cotter pin (Figure 4).
