FLIGHT TRAINING INSTRUCTION T-45 WEAPONS/STRIKE - Cnatra

T-45 WEAPONS/STRIKE CHAPTER ONE
1. Mil Depression Setting (Manual mode). Indicates the mil depression setting of the DSL
reticle on the HUD and is shown in the MAN mode only. The setting is adjusted by using the
SET DEP rocker switch on the DEP. The system initializes at 12 for GUN, 140 mils for BOMB,
and 30 for RKT. The sight can be adjusted from 0 to 270 mils, with 0 being coincident with the
top of the altitude and airspeed boxes (waterline or Armament Data Line (ADL)) and 270 being
toward the bottom of the HUD.
2. Weapon Release Indicator. This cue appears as a small X to the right of the selected
weapon. It is displayed for 2 seconds when the pickle button or trigger is actuated.
3. Weapon Type / Master Arm Indication. The selectable weapons are: GUN, RKTS, and
BOMB. Master arm SAFE status is indicated with an X through the weapon legend. Armed
status is indicated by the absence of the X.
4. Depressed Sight Line (DSL) Aiming Reticle. This cue is a non-computing reticle which
overlays the point a weapon would impact in a no-wind condition, given the weapon type,
airspeed, altitude, optimum G and AOA. This reticle can be adjusted up/down on the HUD
using the SET DEP rocker switch on the DEP. The reticle inner ring is 25 mils, and outer ring is
50 mils. Outside the rings are two (2) additional mil marks along the pitch ladder centerline: 75
and 100 mils (Figure 1-3).
T-45C Manual Delivery Mode - Objective
The objective of the manual delivery is to fly the aircraft in a manner as to arrive at or close to
the planned release parameters (altitude, airspeed and dive angle) with the DSL aiming reticle
close to the intended aiming point. When the aiming reticle is about to overlay the target /
aimpoint, the pickle button / trigger should be actuated to initiate weapons release / firing. In the
Manual delivery mode, the pilot needs to manually compute error corrections required if
deviations occur from the planned release parameters as well as adjust for release wind direction
and velocity. Detailed instruction on techniques of Manual weapons delivery will be discussed
in later chapters.
T-45C A/G HUD CCIP Delivery Mode Symbology
In the CCIP mode, the HUD displays the same flight parameters as in MAN mode (compare
Figures 1-3 and 1-4) with the exception of the aiming sight. CCIP compensates a weapon release
solution based on current aircraft dive angle, bank angle, airspeed, altitude, and release altitude
wind to display a continuously computed impact point for a selected weapon.
In CCIP mode the HUD displays a continuously predicted impact point under the pipper, a
cruciform symbol. A Displayed Impact Line (DIL) is drawn from velocity vector to the pipper,
sometimes called a Bomb Fall Line (BFL). It is only available in A/G BOMB mode, not in
RKTS or GUN. The bomb fall line is an azimuth reference between the pipper and the velocity
vector that indicates wind and speed effects on the weapon. When the target and CCIP pipper are
coincident, you will command bomb release.
