1

Which type of guidance system tracking energy produces a beam of coherent highly
directional and intense light?

Light energy.

2

Which type of guidance system is also known as television guided?

Electro-optical.

3

Which type of guidance system is nothing more than very high frequency radio waves?

Radar.

4

Which type of guidance system gives the pilot a greater stand-off distance?

Global positioning system aided inertial navigation system (GAINS).

5

In which type of guidance system does the weapon send out the tracking energy?

Active.

6

Which type of precision-guided munitions (PGM) hones in on energy reflected off the target
by another source?

Semi-active.

7

What system is actually the brain of precision-guided munitions (PGM)?

Guidance.

8

The purpose of the fixed control surfaces used on guided munitions is to

stabilize the weapon in flight.

9

The purpose of the movable control surfaces used on guided munitions is to

steer the weapon to the target.

10

To move their control surfaces, precision guided munitions (PGM) use either hydraulic,
pneumatic, or

electro-servo actuators.

11

A control system that can make minor or large corrections relative to the flight path of the
target is said to have

proportional navigation.

12

The air-to-air missile proximity fuze detonation occurs when

the missile senses the target moving farther away.

13

What type of rocket motor propellant is used in air-to-air missiles?

Solid.

14

Live missiles must always have a ground wire attached to them to prevent static electricity
from

igniting their rocket motors.

15

What components, minimum, make up a propulsion system?

RM and RM igniter.

16

What warhead does the guided-bomb unit (GBU)–12 laser guided bomb (LGB) use?

MK–82

17

The MAU–169 series computer control group (CCG) consists of a detector,

computer, and control section.

18

Which guided-bomb unit (GBU) laser guided bomb (LGB) uses a 2,000 pound bombs?

GBU–10.

19

What purpose does the WGU–12/WGU–39 series guidance control unit (GCU) seeker
platform assembly serve?

“Look” for the reflected laser light signal.

20

The purpose of the BSU–84 airfoil group (AFG) is to

provide aerodynamic lift and stability during flight.

21

The purpose of the aft faring assembly used on the GBU–24A/B is to

provide an aerodynamic interface between the bomb and wing assembly.

22

What work package (WP) contains procedures for testing a laser guided bomb (LGB) computer control group (CCG)?

WP 080 00.

23

What tester is the TTU–595 designed to replace for field testing all laser guided bomb (LGB) computer control groups (CCG)?

Digital test set, TTU–373.

24

The wing actuator tool used to perform what maintenance task?

Open and close the wings.

25

The typical Joint Direct Attack Munition (JDAM) tail assembly consists of a tail fairing/structure, tail actuator subsystem (TAS), wire harness assembly, guidance control unit (GCU),

GPS antenna, three moveable control fins, and one fixed fin.

26

Which type of guidance system does the Joint Direct Attack Munition (JDAM) use?

Global positioning system (GPS) and inertial navigation system (INS).

27

Which statement is not a benefit of off-axis delivery of the Joint Direct Attack Munition (JDAM)?

Provides increased weapons range.

28

What Joint Direct Attack Munition (JDAM) guidance set components provide lift and maneuverability?

Aerosurfaces.

29

Which guided-bomb unit (GBU) uses a 2,000 pound warhead?

GBU–31

30

Which guided-bomb unit (GBU) decreases the likelihood of collateral damage?

GBU–38.
