TM 11-5840-281-12-1
4-28. CIRCUIT ALINEMENT. (CONT)
CURSOR ALINEMENT (CONT)
NOTE
For left-of-runway coverage, azimuth cursor will curve up. For right-of-runway coverage,
azimuth cursor will curve down.
8.
On pulse generator, identify td range mark (1) and adjust applicable PREC DELAY control so that td range mark
(1) passes through leading edge of td bracketing target simulator return (2) on azimuth display.
9.
On pulse generator, adjust applicable OFF SET control so that azimuth cursor (3) bisects distance between td
bracketing target simulator return (2).
NOTE
By placing ANGLE VOLTS switch back and forth in OPERATE and AZ positions, artificial
sweep trace and rpl target simulator return can be viewed at the same time.
10.
Alternately change ANGLE VOLTS switch on pulse generator between OPERATE and AZ positions.
11.
On pulse generator, adjust ART ANGLE V control until artificial sweep trace (4) bisects rpl target simulator return
(5). Record ART ANGLE V control dial indication.
12.
For left-of-runway coverage, add ART ANGLE V control dial setting, representing azimuth offset angle previously
determined, to dial indication recorded in step 11. For right-of-runway coverage, subtract dial indication
representing azimuth offset angle from dial setting recorded in step 11. New dial indication (sum or difference) is
5-mile intercept setting. Record this value for use in subsequent azimuth cursor alinements.
13.
Determine 5-mile intercept setting of ART ANGLE V control for each approach by performing steps 8 through 12.
