the amount of time or vane revolutions needed for the firing train to be aligned after a bomb is released is known as?
arming time
the action that causes a fuze to detonate before impact when any substantial object is detected at a predetermined distance from the fuze is known by what term?
proximity
the time required for a fuze to detonate after impact or a preset time is known by what term?
functioning time
what term applies when the functioning time is longer than 0.0005 second?
delay

what term applies when the functioning time of a fuze is 0.0003 to 0.0005 second?
nondelay
a fuze that does NOT have the elements of its firing train in the proper position for firing until the fuze is fully armed is known as what type of fuze?
a detonator-safe fuze
the distance along the trajectory that a bomb travels from the releasing aircraft in an unarmed condition is known by what abbreviation?
SAT
in reference to their primary operating principles, fuzes are normally divided into what two general classes?
mechanical and electrical
a bomb that is accidentally released during an aircrafts landing or takeoff will NOT normally have sufficent air travel, velocity, or time to fully arm the fuze because of what fuze feature?
delay arming
the two observation windows of an M904 series fuze are used for what purpose?
to determine the safe/arm condition
you can determine if a fuze is safe or armed by what means?
