Q factor

[′kyü ‚fak·tər]
(ordnance)
A correction factor applied to a bombsight setting to help account for the differing winds between flight altitude and the ground; this factor corrects only for that component of the differential ballistic wind that is parallel to the actual wind at flight level.
