Real Time Gun Sight (RTGS)

HUD/MFD Data Entry Procedures

T-45C TS, ADV & IUT TFFP-01

2. Method of use: with the HUD properly set, target's

wingspan should fill inner area of aiming reticle while

firing (inner radius = 1000 ft range) with no need to lead

target; requires one second of tracking prior to firing

3. Real Time Gun Sight (RTGS)

a. Description

(1) Designed for gun aiming against maneuvering

target

(2) Aiming reticle indicates instantaneous impact

point of the round at 1000 ft; employed in guns

tracking and raking attacks

(3) Solution always valid

b. Method of use

(1) For guns tracking a maneuvering target: once

in range establish reticle with 1/3 sec lead to

compensate for bullet time of flight (TOF)

(2) For raking attack when target is anticipated to

cross your nose with high angle off within gun

range: once in range, put reticle where target

will be in 1/3 second and fire; target should fly

into stream of bullets

4. Missile

NOTE: There is no specific submode in the HUD for

air-to-air missile firing. To provide adequate missile

aiming information with the HUD, center the bogey on

the HUD's heading reference, which approximates the

aircraft's armament datum line at high airspeed and

under moderate G force.
