Weapons Delivery Principles And Procedures
WEAPONS DELIVERY PRINCIPLES AND PROCEDURES
Up to this point, we have discussed procedural matters. We now come to the most important topic
of all: how to deliver the weapon onto the target. All the procedures discussed, though they are
certainly important, have one common purpose: to allow you to arrive at the roll-in point. It is what
you do between roll-in and release that will determine the accuracy of your delivery. In order to
introduce the procedures to be used during the weapons run, we must first discuss some of the
basic principles involved. This discussion is of necessity brief, and the mathematics have been
shortened or deleted.
THEORY OF WEAPONS DELIVERY
(See Figure 25)
Line of Flight
The path of the aircraft through the
The angle between the line of flight
and the ground.
Line of Sight
A line from the pilots eye through
the pipper. This line does not
normally pass through the target
Armament Datum Line
Note: Location of ADL is compensated
for in sight depression tables.
The armament datum line (ADL) is
a fixed reference line on the
aircraft. It will be parallel with the
flight path at 450 kts TAS release
airspeed. At other than release
airspeed, it will vary from parallel.
The angle between flight path and
ADL is called the angle of attack of
the armament datum line; this is
not the same as the AOA mea-
sured by the aircraft instrument.
Figure 25: TERMINOLOGY
This angle decreases to zero
(ideally) as the aircraft accelerates
to 450 kts TAS, so flight path and armament datum line are the same at release airspeed.
The angle between the ADL and the line of sight, sometimes called sight depression angle. With a
sight angle of zero, the line of sight is parallel to the ADL. With any depressed sight angle, the line
