CBAT-O (Military Aircraft Survivability Equipment) Questions With
solved Answers
TOPIC 1: ADVANCED THREAT INFRARED COUNTERMEASURES (ATIRCM)
1. ATIRCM tracks missile threats and uses directed ____ energy to disrupt the missile's
ability to track its intended target.
A) Radio Frequency
B) Microwave
C) Laser
D) Ultraviolet
ANSWER: C) Laser
Rationale: ATIRCM uses a high-energy laser to jam an incoming missile's infrared seeker.
[citation:1][citation:2][citation:5]
2. The ATIRCM is specifically designed to counter which type of missile threat?
A) Radar-guided missiles
B) Infrared (IR) guided missiles
C) Ballistic missiles
D) Wire-guided missiles
,ANSWER: B) Infrared (IR) guided missiles
Rationale: ATIRCM is a laser-based system designed to defeat heat-seeking, infrared-
guided missiles. [citation:1][citation:4][citation:5]
3. To improve warning and protection from IR guided missiles, ATIRCM integrates with
which system?
A) AN/APR-39 RSDS
B) Common Missile Warning System (CMWS)
C) Radar Altimeter
D) TACAN
ANSWER: B) Common Missile Warning System (CMWS)
Rationale: ATIRCM relies on CMWS to detect and cue it to incoming threats.
[citation:1][citation:2][citation:7]
4. At the ____ threshold, the CMWS ECU hands off the spatial coordinates of the target of
interest to a JHCU.
A) Lethality
B) Cue
C) Launch
D) Bearing
ANSWER: B) Cue
Rationale: The "Cue" threshold triggers the hand-off from the CMWS to the ATIRCM's Jam
Head Control Unit (JHCU) for precision tracking. [citation:1][citation:2][citation:4]
5. The JHCU acquires and tracks targets using the IR tracker sensor in the ____.
A) CMWS ECU
,B) Control Indicator (CI)
C) Infrared Jam Head (IRJH)
D) User Data Module (UDM)
ANSWER: C) Infrared Jam Head (IRJH)
Rationale: The IRJH contains the high-resolution tracker that locks onto the threat after
cueing. [citation:1][citation:2][citation:7]
6. ATIRCM uses a Class IV laser which can cause eye and skin damage from more than
_____ feet away.
A) 50
B) 100
C) 200
D) 500
ANSWER: B) 100
Rationale: Class IV lasers are highly dangerous and pose a significant hazard at distances
greater than 100 feet. [citation:1][citation:2][citation:7]
7. The ATIRCM ______ of the Infrared Jam Head is used to radiate laser energy to jam
threats.
A) Laser aperture
B) Cooling system
C) Gimbal mount
D) Power supply
ANSWER: A) Laser aperture
, Rationale: The aperture is the opening through which the laser energy is directed at the
threat. [citation:1][citation:2][citation:4]
8. ATIRCM powers up simultaneously with CMWS. Approximately how long is the system
offline and unable to protect the aircraft?
A) 1 minute
B) 5 minutes
C) 10 minutes
D) 30 seconds
ANSWER: B) 5 minutes
Rationale: During the power-up and initialization process, the system is unavailable for
approximately 5 minutes. [citation:1][citation:2][citation:5]
9. ATIRCM interconnects with CMWS safety interlocks to ensure personnel are protected
from inadvertent ____ radiation.
A) Radio Frequency
B) Microwave
C) Laser
D) Ultraviolet
ANSWER: C) Laser
Rationale: Safety interlocks prevent the ATIRCM's high-power laser from firing on the
ground, protecting personnel. [citation:1][citation:2][citation:7]
10. Which component of the ATIRCM system is used to jam threats with laser energy?
A) The CMWS ECU
B) The Laser Aperture
