Exam 3 Flashcards
What best describes the Starter Generator? (SG)
Produces 9kW 28V dc power at sea level
Battery configuration
Fitted in two sets of three:
- 1,3,5 provide power to Bus 1 BJB
- 2,4,6 provide power to Bus 2 BJB
What best describes the DCPS? Digital current power supply
Converts DDBA 3-phase V ac into 28V dc
Describe BJB 1 (‘all of the above’)
- distributes SG 28V to Bus 1
- provides isolation between Bus 1 and Bus 2 for redundancy
- provides circuit protection fusing
Power Supply Bus Bar
Batteries 1,3,5 provide backup power in the event of SG failure
Best describe the two PPDMs - payload power distribution module
Distributes 28V dc to connected components
What is to be carried out prior to conducting the relevant check list in the event of an engine failure? (‘All of the above’)
- Time: note time the failure occurred
- speed lever - high
- diagnose failure
What is the primary indication of a starter generator failure?
Bus 1 Bat/Gnd A >10A
What is the primary indication of a DDBA failure? (‘False’) direct drive brushless alternator

What is the primary indicator of a dual generator failure? (‘False’)
Bus 1 Bat/Gnd A >10A and DDBA power <1800W

Emergency mission
Where is the PRF code located on the HUD?
Top left
Can the LTM be seen with the naked eye?
No, requires Night Vision
What is the safe distance for the LRD for the naked eye?
Slant range of 46.7km
What is the safe distance of the LTM?
Slant range of 324m for naked eye, skin hazard 28m
How can you toggle between the LTM and LRD?

What is the VIT for SAR (PPDM) data?
Payload power distribution module
VIT53
How are the screens of the HDD named?
L - Status

Electromagnetic spectrum
How long for NUC 1 + 3 to process?
NUC 1 - 6 secs
NUC 3 - 50 secs
What are the two digital fields of view?
2x and 4x
What does the red button on the control stick do?
Toggles between primary source (LL, IR or DTV when viewing fused video)
What mode does the camera power up in?
IR
What is the laser action when lost link?
Automatically sets to OFF and DISARMED
What are the different image processing modes?
Local Area Processing (LAP) Linear Processing (LIN) Rayleigh Processing (RAY) Manual Adjustments (MAN)
How many track gates are there?
12
What do you do if you have a Gimbal Disable condition with an asterisk?
Do not initiate AN/DAs- reset
What happens when tracker enters Coast Mode?
When tracked target is lost because it is obscured. LOS continues to move at last valid rate and direction until target reacquired or track cancelled.
Coast mode indicated by track gate corners flashing. If system fails to reacquire track after 5 seconds it automatically cancels and reverts to rate mode.
What are the 3 Track Modes?
Point track - sensor aligned with area of significant contrast
Area track - sensor aligned with specific scene
Feature track - sensor maintains lock on moving tgt
How do you make safe and arm the laser?
In the LTM control entry mode selection menu
What are the two types of Change Detection output?
Amplitude CD (ACD) Enhanced CD (ECD)
What is the gim dis over heat threshold?
85 degrees
How many track gates can you have
12, locks onto nearest to cross hairs
Where is the gim dis displayed?
Middle left
