Gunnery skills test with complete solutions | 2025
If several projectiles are fired from the same weapon with the same elevation and
deflection settings, the degree of scatter of the aim points is called - ☑️☑️Scatter
The altitude fired from and range to the target determines (blank) and (blank) -
☑️☑️Impact pattern, fragmentation pattern
Fragmentation pattern length (blank) with high angle impacts - ☑️☑️Decreases
What are the interior ballistics? - ☑️☑️Barrel west, propellant charges, projectile weight,
launcher tube and rocket pod alignment, thrust misalignment
What are exterior ballistics? - ☑️☑️Air resistance, gravity, yaw, projectile drift, wind drift
What are Aerial ballistics - ☑️☑️Rotor down-wash, angular rate, turning bank, propellant
force, center of gravity, relative wind effect, trajectory shift, port-starboard effect,
projectile jump
What are terminal ballistics - ☑️☑️Blast, heat, and fragmentation and influenced by fuse
and warhead functioning, impact angle, and surface condition
Define max effective range. - ☑️☑️The max range at which there is a 50% probability of
both hitting and defeating a target.
Define Ballistics - ☑️☑️The study of projectile motion and the conditions affecting that
motion
What are the 4 types of ballistics - ☑️☑️Interior, Exterior, Aerial, and Terminal
Can the crew compensate for interior ballistics? - ☑️☑️No
What is the cause of greatest error for free flight rockets? - ☑️☑️Inherent Thrust
misalignment
Which exterior ballistic is not compensated for by the weapons processor/mission
processor? - ☑️☑️Yaw
What exterior ballistic causes a clockwise spinning projectile to move to the right? -
☑️☑️Projectile drift
, Why is the aerial rocket system more accurate from an OGE hover than IGE? -
☑️☑️Because the aircraft cannot apply appropriate down wash compensation due to a
random induced flow pattern
What is angular rate error and how do you compensate for it? - ☑️☑️Caused by motion
(pitch, yaw, roll) in the launch platform as the projectile leaves the platform.
Compensate by steadying the platform.
What are the aerial ballistic characteristics affecting fin stabilized projectiles. -
☑️☑️Propellant force, CG, relative wind
What causes a rocket to seek into a crosswind or impact past the target when fired
during an accelerated climb? - ☑️☑️Relative wind effect
What is projectile jump and when does it occur when firing from a hover? - ☑️☑️Occurs
when the crew fires a weapon and the weapons muzzle is pointed in a direction other
than the relative wind. Occurs due to the precession induced by crosswind
Is projectile jump compensated by the WO/MP? - ☑️☑️No
What determines the amount of lead required when firing off axis to the left or right? -
☑️☑️Aircraft speed, angle of deflection, projectile velocity, and target range.
What is it called when projectile drift and trajectory shift combine with each other? -
☑️☑️Port/starboard effect
What three factors affect dispersion discussed in conjunction with terminal ballistics -
☑️☑️Vibration, sights, boresights
Define spall - ☑️☑️Additional type of fragmentation by target structure itself
At approximately(blank) knots indicated airspeed, the influence vector is moved just aft
of the rocket launcher bulkhead, thus reducing downwash to (blank) - ☑️☑️33, zero
With the (blank) selected as the sight, lead angle compensation is not computed or
added to the gun turret or rocket pylon position command, nor is the target state
estimator employed. - ☑️☑️IHADSS
What is the gunner's triangle? - ☑️☑️Target ID
heading to target
Range
Store
