Question 3

Heart of helicopter threat warning suite:

Answer 3

APR-39

Question 4

Provides visual and aural indications for the presence of and bearing to active radar transmitters:

Answer 4

APR-39

Question 5

APR-39 consists of:

Answer 5

• 4 spiral antenna detectors- 2 on nose, 2 on aft pylon
• 2 video receivers- 1 in nose, 1 in aft pylon
• 1 blade antenna- bottom of aircraft
• 1 digital processor- in the cabin ceiling at STA 306
• 1 UDM (User Data Module) inserted into digital processor.

Question 6

APR-39 digital processor does what:

Answer 6

Sends data to indicator (APR-39) and ECU (CMWS)

Question 7

Contains classified information for threat detection:

Answer 7

UDM- User data module- inserted into digital processor

Question 8

APR-39 display on center instrument panel shows:

Answer 8

• Threats relative position from helicopter
• Position relative to the center shows the lethality
• Displays a maximum of 7 threat symbols
• U = detected threat cant be identified

Question 9

APR-39 display signals:
\+
\+ flashing
F
P flashing

Answer 9

+ indicates ASE is fully operational
+ flashing- dense signal environment, detection is degraded
F- Subsystem has failed some portion of PBIT
P flashing- RSDS digital processor failed IBIT

Question 10

Do not operate RSDS within:

Answer 10

60 yards of ground based radars or 6 yards of airborne radar antennas

Question 11

Common Missile Warning System (CMWS)- AAR-57 detects:

Answer 11

In-band infrared and UV radiation emitted from missile plum.

Question 12

CMWS consists of:

Answer 12

• 5 EOMS (electro-optical missile sensor)- 2 forward pylon, 2 aft, 1 underneath.
• 1 electronic control unit (ECU)
• 1 UDM (User Data Module) inserted into ECU
• Requires 2 minute warm up/ DO NOT abort power up & initialization

Question 13

Improved countermeasure dispenser (ICMD)

Each payload module assembly has:

Answer 13

30 chambers

Question 14

External countermeasure system designed to protect aircraft from:

Answer 14

Anti-aircraft artillery (AAA)
Surface to air missile (SAM)
Airborne intercept (AI)

Question 15

8 externally mounted dispensers:

Answer 15

• 4 chaff dispensers, 2 on each side
• 4 flare dispensers, 2 on each side
• M-1 chaff - silver, non descript

Question 16

8 externally mounted dispensers:

-Flares:

Answer 16

M-206 - red “F”
M-211 - grey around the edge, yellow circle
M-212 - solid yellow

Question 17

3 ASE safety devices:

Answer 17

• Safety pin in cabin
• SAFE switch on ASE panel on center console
• Proximity switches (WOW)
  
  • Right WOW switch- disables flare and chaff
  • Left WOW switch- prevents cancellation of mode 4 codes
