1.5.9. DEPRESSIBLE RETICLE SWITCH

MANUAL bombing mode selected through the SMS A-G MFD (OSB #16) uses a backup bombing

reticle that is normally used when the primary systems and avionics have failed.

The manual bombing reticles are controlled by the DEPR RET switch on the HUD panel. The switch

has three positions and features a primary (PRI) and standby (STBY) reticle. The reticles are

comparable in use to old WWII aiming devices.

The Primary reticle does not change actual HUD symbology (except for the bombing mode symbols)

and consists of a centre pipper with a dashed inner circle (50mil) surrounded by a solid outer circle

(100mil).

The reticle can be moved UP and DOWN in the HUD by using the DEPR RET ICP wheel (top right

wheel). The depression is displayed on the left of the HUD in milliradians.

The standby reticle is a centre cross with a dotted inner circle (50 mils) surrounded by another dotted

circle (100mil). The STBY reticle blanks out all other HUD symbols except the mil setting set by the

ICP DEPR RET wheel. The standby reticle is visible even with the HUD damaged.
