INTERCEPT PROCEDURES TEXTBOOK
LD is a function of TA and SR only. Turning room has no relationship to DTG or whether
the bogey is on CB. All you need to know is the TA, both in amount and direction, to properly
execute the DT. For example, given a 160 DTG L-R, set-up (20°L cut) with the bogey DA at
10 nm, the weapons officer determines TA to be 20ºR. 20ºR TA is displaced to 30ºR AO at
Slowing Loss of Lateral Displacement
In all situations with what rounds to greater than 25º of TA, the fighter will have an excess of
turning room. In this case, the purpose of the DT will be to slow the rate of loss of lateral
displacement. Again, the bogey will be repositioned 25º off of the new CB once the fighter is
steady from the DT. Also remember that right TA displaces to the right side of the scope and left
TA displaces to the left side of the scope.
Example: BH 240º, FH 360º, BB 025º, AO 25ºR at 9 nm, TA 35ºL
Note that 35ºL TA at 8 nm gives the fighter more than 20,000 feet of LD (28,000' to be
exact). The fighter need only slow the loss of LD. A right displacement turn of 40º will
reposition the bogey to 15ºL. Note that the DT itself is not necessarily 50º, but that the bogey
will be repositioned at a point 25º from the new CB for the amount of TA.
