Q

What two factors create most of the Parallax Effect?

A

Angular difference between the M-PNVS and the HDU, and the distance from the item being observed. (Close-in at a 90 degree angle is the worst)

Q

What is FLIR polarity?

A

FLIR polarity is a shade reversal effect applied to the FLIR in order to view an item more clearly. The resulting selection is referred to as “White Hot” and “Black Hot”

Q

How can a crewmember tell what polarity their FLIR system is using?

A

Look at the sky (Clear Sky)
Sky Dark = White Hot
Sky Light = Black Hot

Q

What are the four considerations for FLIR optimization?

A

FLIR must be cooled
Scene rich in detail
Select a polarity
Only one control should be adjusted at a time

17
Q

Which should be optimized first, the FLIR or the IHADSS?

A

IHADSS

18
Q

What is the definition of FLIR optimization?

A

Using a combination of level and gain to achieve the best detail

19
Q

What is the primary objective of FLIR adjustment?

A

Obtaining the highest possible picture quality for the flight environment (obtaining a quality image).

20
Q

What two things should crewmembers ensure before they optimize the FLIR?

A

Ensure that the “NVS NOT COOL” or “FLIR NOT COOL” message is no longer present and that the “ACM” is OFF

21
Q

When is an optimization required?

A

Required when the crew is going to use the FLIR for Flight, Laser Ops, and Weapons.

22
Q

What establishes the FOV of the M-PNVS?

A

Afocal Assembly

23
Q

How can the crewmember in control of the M-PNVS stow it?

A

Place the NVS Mode Switch to OFF

24
Q

What symbology is always presented on the M-PNVS display?

A

Flight

25
Q

What does the NORM position provide the pilot?

A

Provides M-PNVS video that is slaved to the pilot’s helmet mounted display (HMD).

26
Q

What does the FIXED position provide the pilot?

A

Provides the pilot with a M-PNVS that is fixed forward at 0 degree’s in azimuth and -4.9 degrees in elevation

27
Q

The M-TADS is divided into what two major sections?

A

M-DSA
M-NSA

28
Q

What major components are located within each section of the TADS?

A

M-DSA= DTV, LST, LRFD

M-NSA= FLIR

29
Q

What must crews ensure on preflight for M-TADS operation?

A

Covers OFF – M-DSA Cover, M-NSA Cover, Boresight Module Cover

30
Q

Why is the M-TADS resolution not as good as the resolution of the M-PNVS?

A

M-TADS was not designed for Flight. It was designed for targeting. (M-TADS is a Medium Resolution FLIR) f/2.3 vs f/1.5

31
Q

When is the M-TADS not an available selection as a Sensor?

A

When the NVS Mode Switch is “OFF” (It is available as a Sight when the NVS Mode Switch is “OFF”).

32
Q

If the CPG is using the M-TADS as a Sight and it is required for NVS flight, what must the CPG do to gain control of the M-TADS as a Sensor?

A

Place the NVS Mode Switch to NORM or FIXED.

33
Q

If either crewmember selects M-TADS from a Sight to a Sensor, what image will be displayed on the HDU?

A

FLIR image, Wide FOV

34
Q

What symbology will be displayed on the HDU when using M-TADS as a Sensor?

A

Flight Symbology

35
Q

What is the fixed field of view of the M-TADS when used as a Sensor?

A

30 X 40

36
Q

What is the slew rate of the M-TADS?

A

60 degrees per second

37
Q

What are the two stow positions for the M-TADS when not in use?

A

TADS STOW 180º
TADS Alternate Stow: 0º Azimuth, 0º Elevation and not being used as a Sight or Sensor

38
Q

Which crewmember can stow the M-TADS?

A

CPG

39
Q

How can a crewmember select the opposite sensor?

A

NVS Mode switch other than OFF (IE: NORM or FIXED), NVS Select Switch to selected sensor

40
Q

Can the pilot always select M-TADS from the CPG?

A

Yes

41
Q

Can the CPG always select M-PNVS from the pilot?

A

Yes

42
Q

If both crewmembers are using a sensor, what happens if either crewmember selects the NVS Select Switch on the Collective Flight Grip?

A

Sensor Swap
