WPN UTIL- LOAD

25
Q

Can you confirm sight select on the WPN page?

A

Yes

26
Q

What will be displayed in the HAD weapon inhibit field during weapons training mode?

TRAINING

27
Q

A

888

28
Q

In gun harmonization, to improved accuracy, the CPG places TADS on a target between what ranges?

A

50 - 1500m

29
Q

Laser pointed is used for target _____ and _____

A

Illuminating and pointing

30
Q

To distinguish one laser pointer from another using hi or low from another pointer, ____ can be selected

A

PULSE

31
Q

When the laser pointer boresight fail status window appears the crew member should repeat the steps. T/F?

A

True

32
Q

When the weapons trigger is activated the laser pointer is deactivated. Gun fire could be delayed by how much?

A

.75 seconds

33
Q

The sun burst symbolically is displayed to both crewmembers upon activation of the laser pointer. T/F

A

True

34
Q

What are the 4 types of ballistics that affect helicopter fired weapons?

A

Interior, exterior, aerial, terminal

35
Q

what is turret bending and will the MP compensate for it?

A
  1. Airframe and gun turret experience flexure in response to sustained recoil
  2. MP will compensate, 1st round none, 2nd round 70%, 3rd and all after 100%
36
Q

The gunner must compensate for lead angle in which sight? Why?

A

HMD
MP does not provide TSE algorithm when HMD is sight selected.
