Troubleshooting — Getting a Valid Lock
Longbow, Kiowa
For Hellfires, getting and keeping a valid lock essentially means keeping the
missile’s seeker head pointed in a direction that allows it to find its target. When you
choose Hellfires, a target box appears on your IHADSS. If you are in LOAL missile
launch mode, this box is much larger than it is in LOBL missile launch mode.
The box marks the seeker’s field of view. Position it in the general direction of
your target; when it turns solid, you have a valid lock. If it is dashed, you do not
have a valid lock. The text in the weapon inhibit field explains why you do not
have a valid lock and helps you correct.
Weapon Inhibit Field
Longbow
Messages displayed in this field tell you whether you have a valid lock, and how
to correct in order to get one if you don’t. These messages are useful only for
Stingers, MPSM FFARs and Hellfires, as HE FFARs use constraints instead of a
lock.
VALID LOCK The target is valid and you can fire your weapon.
NO TARGET You do not have a target selected.
NO ACQUIRE Your radar (in FCR mode) or laser (in TADS mode) is off. You
need to activate the appropriate target acquisition system before
you can lock up a target.
ARM? Master Arm is set on “safe.” (This is equivalent to the plastic
safety cup that folds down over the weapons trigger in a real
helicopter to keep the trigger from getting pressed accidentally.)
Press cM to free your weapons.
NO MSLS You have run out of the type of missiles you’ve selected.
OUT OF RANGE The current target is beyond the maximum range of the current
weapon. Choose a closer target or move toward your current
target until it comes into range.
