Building Lateral Separation in the Intercept

INTERCEPT PROCEDURES TEXTBOOK

Fighter steadies on a heading of 010 (10 from collision heading). New collision bearing is

005, with the bogey 5 off CB at 30 nm. Bogey bearing is 10 off CB at 15 nm. TA will

increase 5 degrees (from 10R to 15R).

Example #2

BH = 180

BB = 010

TA = 10R

CH = 020

Fighter steadies on a heading of 350 (30 from collision heading). New collision bearing is

355 with the bogey 15 off CB at 30 nm. Bogey bearing at 15 nm will be 025. TA will

increase 15 (from 10R @ 30 nm to 25R @ 15 nm).

Example #3

BH = 180

BB = 010

TA = 10R

CH = 020

Fighter steadies on a heading of 060 (40 from CH). New collision bearing is 030 with the

bogey 20 off CB at 30 nm. Bogey bearing at 15 nm will be 350. TA will change 20 in 15 nm

(from 10R to 10L).

Building Lateral Separation in the Intercept

It is important to recognize LS goals before they occur. Using the formula LS = TA X SR X

100, compute the LS off of GCI calls or a contact on the scope, and reconvert if necessary.

Continued analysis throughout the intercept will be required to monitor LS. The key to staying

on top of LS growth is calculating it early on into the intercept and keeping an eye on it as it

continues to grow. Unlike TA, which changes exponentially as range decreases, LS grows at a

constant rate with range if the same heading is maintained. The fighter should (in area I, II, and

III problems) calculate LS once they have rolled out on their initial cut (based upon the

gameplan) in use, using the TA and range derived from either GCI calls or scope analysis.

From that point, the fighter can monitor LS and get a feel for how quickly the LS goal is

being reached.

Because time is critical, round off numbers so they are easier to multiply.

For example: 19 TA x 21 nm =̃ 40K

Remember, LS goals also apply to a TA problem since TA at Fox-1 range determines our

available LS.
