HGST MAY 2014 Flashcards
The engagement process is a systematic fires cycle and a continual process on any mission and has five tenets;
Detect, Identify, Decide, Engage and Assess (DIDEA). (TC 3-04.45 PG 11-1)
A target is _______ when it is temporarily taken out of the battle. Neutralizing a unit allows the maneuver commander to decide whether to continue to engage with indirect fires, maneuver to the target and engage with direct fires or bypass a target and proceed with other missions.
neutralized (TC 3-04.45 PG 15-3)
_______ is a decisive engagement that puts a target out of action permanently. A unit with _______ or more casualties is usually rendered permanently ineffective, depending on the type and discipline of the force. Direct hits are required on hard materiel targets.
Destruction, 30 percent (TC 3-04.45 PG H-23)
The method of attacking a target is governed by the results desired: _________, __________, or __________.
Suppression, neutralization, or destruction (TC 3-04.45 PG H-23)
The four types of ballistics influencing projectiles fired from helicopters are ______, ______, ______, and ______.
interior, exterior, aerial, and terminal. (TC 3-04.45 PG A-6)
Interior ballistics includes: ______, _______, _______, _______, _______.
Barrel Wear, Launcher Tube Alignment, Thrust Misalignment, Propellant Charge, and Projectile Weight (BLTPP). (TC 3-04.45 PG A-7)
Gravity, Yaw, and Wind Drift are what type of ballistics?
Exterior (TC 3-04.45 PG A-8)
What two factors determine the amount of wind drift of a projectile.
Time of flight, Wind speed acting on the cross-sectional area of the projectile (TC 3-04.45 PG A-9)
Yaw is the angle between the centerline of the projectile and its trajectory which results in the projectile’s trajectory changing which increases _____. Where would a projectile have its maximum Yaw?
Drag, Near the muzzle. (TC 3-04.45 PG A-8)
The exterior ballistic which causes a clockwise spinning projectile to move to the right is called?
Projectile Drift (TC 3-04.45 PG A-8)
_________ and _________ combine to constitute the port-starboard effect.
Trajectory shift, projectile drift. (TC 3-04.45 PG A-13).
Aerial-fired weapons characteristics derived from fin or spin-stabilized munitions and whether they are fired from a fixed or flexible mode. Common errors for these munitions are___________
rotor down-wash error, angular rate error, and turning bank error. (TC 3-04.45 PG A-9)
In general, at ranges less than _______, the effect of trajectory shift is greater. At ranges greater than _______, the effect of projectile drift is greater and tends to cancel the effect of trajectory shift.
1000 meters, 1000 meters. (TC 3-04.45 PG A-14)
AH-64D pilots should recognize that compensation for trajectory shift is accomplished automatically by the weapons processor if: a__________ b________
a. TADS is the selected LOS (Seven-state Kalman filter)b. FCR is the selected LOS (Scan-to-scan correlation) (TC 3-04.45 PG A-21)***NO lead-angle compensation is computed or added when IHADSS is the selected sight.
_____________: Firing to the right produces a downward jump; firing to the left produces an upward jump. ______________ is required in hover if a relative wind exists. Pilots must recognize compensation for aeroballistics drop is accomplished automatically by deriving the munitions angle of attack with respect to wind vector and applying the appropriate jump correction to the aiming algorithm.
Projectile Jump, Projectile jump correction (TC 3-04.45 PG A-25)
___________ is caused by the motion (pitch, roll, and/or yaw) in the launch platform as a projectile leaves the weapon.
Angular rate error (TC 3-04.45 PG A-10)
__________ is effectively negligible for 30-mm projectiles, but it can affect rocket accuracy if rates are appreciable. __________ induce angular rates in the pitch axis up to 10 degrees per second.
Angular rate error, Articulating pylons (TC 3-04.45 PG A-24)
What are three factors that effect dispersion?
Vibrations, Sights, Boresights (TC 3-04.45 PG A-15)
Angle of Impact is a characteristic of what type of ballistic?
Terminal Ballistic (TC 3-04.45 PG A-15)
Because the rocket is accelerating as it leaves the launcher, the force acting upon the fins causes the nose of the rocket to turn into the wind. This is known as the __________.
relative wind effect. (TC 3-04.45 PG A-12)
What is the cause of the greatest error for free flight rockets (besides poor pilot technique) and what is done to minimize that error?
Thrust Misalignment, Rocket spin (TC 3-04.45 PG A-7)
Maximum effective range is defined as:
the longest range at which a weapon has a 50% probability of hitting a target. (TC 3-04.45 PG A-4)
The MPSM submunition (M73) will land __ degrees off center ___ percent of the time, resulting in a 90% probability of producing personnel injuries within a ___ meter radius.
5 degrees, 66 percent, 20 meter (TC 3-04.45 PG 14-30)
Hellfire II missiles Maximum velocity is approximately _______ per second.
475 meters (TC 3-04.45 PG D-8)
