MTS/FLIR System Flashcards
How many cameras?
Four.
Two for DTV
One for LLTV
One for IR (its called an “IR Sensor”, not a camera, but whatever)
To which “camera” is the LRD boresighted?
The IR camera
In which modes can you use digital zoom?
IR mode.
2X and 4X. They just zoom in on that image, they are not a different field of view of the camera. So it might get blurry.
What is LOS and what does it do?
Line of Sight Stabilization.
Provides a steady image despite helicopter movement and allows for AVT lock
What are the three automatic processing modes?
Local Area Processor (LAP)
Linear Transform Processor (LIN)
Rayleigh Transform Processor (RAY)
What is Local Area Processing (LAP)?
This is preferred.
Looks at entire display then does level and gain adjustment for individual parts of the screen to give you the best image.
What is Linear Transform Processing (LIN)?
looks at overall contrast and sets the level and gain for the whole display at once.
What is Rayleigh Transform Processing (RAY)?
Like LIN, but shows more contrast in darker displays.
What is Level?
Adjusts the temperature the MTS will sense and sets the black bias
What is Gain?
Sets the temp range for a given level
What are the two types of Polarity and what are they good for?
White Hot: for drawing attention to bright objects in a dark scene. (overwater)
Black Hot: for a more realistic image of the scene and helps to see or confirm a cue pattern.
What can you do with the Right Control Switch (RCS)?
Down: Toggle between Nav and Attack modes
Right: Change polarity
Left: Freeze/unfreeze
Press: Main Menu
Press and hold for 1 second: 1-point NUC
What is the purpose of Grayscale?
Used for optimizing brightness and contrast. If your FLIR Image looks like shit, you probably have contrast up too high on you Mission Display.
How many switches have to be “On” in order to use the laser, and where are they?
Three laser switches and the Master Arm switch in “Arm”
Nose bay, in the cockpit next to the master arm switch, and on the SO Console.
What is Automatic Video Track Mode?
AVT Lock Slaves the MTS based on movement of a Target.
Hold down the trigger guard on the HCU until the track gate (rectangular area) fully envelopes the target.
It isn’t affected by polarity or processing mode.
If in fusion mode, it does not consider DTV, only cares about IR Image.
What are Acquire Aids?
Creates smaller track gates inside the AVT track gate. It looks for man-made strong edges. When you release the Trigger guard, AA passes a track block to AVT. It is designed to choose the track box closed to the reticle that has a strong edge.
What is the default AVT Track mode?
Gradient (GTRK)
Receives pitch, roll, and yaw from the EGIs, altitude from the RADALT, and guards against masking of the target. the more edges or shapes inside the track gate, the better the lock.
Which AVT Track mode should you never use, and why?
Raytheon, because it doesn’t actually work as it is designed.
(So don’t bother memorizing what it is supposed to do, since it doesn’t work).
Which laser can be seen through NVGs?
the LTM
What are the modes of the LTM?
Continuous
Fast Blink (3/sec)
Slow Blink (once every 2 sec)
Do the detents on the Trigger affect the LRD?
Yes.
First detent is just ranging, second detent is the LRD for weapons.
What are NUCs?
Non-Uniformity Correction, analyses and corrects each pixel to the IR receiver, then stores those corrections.
NUC1 = pixel response in one temp (17sec)
NUC2 = pixel response in various temps (30sec)
FIRST PULSE vs. LAST PULSE
First: laser receiver responds to the closest object.
Last: furthest target (use this with Precision Weapons)
LRD in cold weather
May not fire or boresight correctly below -10 Celsius
What is the Ground Intercept Point (GIP)
Symbol on the GEOSIT where the FLIR LOS intersects the Earth’s surface. Displays when Wight off Wheels and EGI data is valid.
