tilt

[tilt]
(aerospace engineering)
The inclination of an aircraft, winged missile, or the like from the horizontal, measured by reference to the lateral axis or to the longitudinal axis.
(electromagnetism)
Angle which an antenna forms with the horizontal.
In radar, the angle between the axis of radiation in the vertical plane and a reference axis which is normally the horizontal.
(meteorology)
The inclination to the vertical of a significant feature of the circulation (or pressure) pattern or of the field of temperature or moisture; for example, troughs in the westerlies usually display a westward tilt with altitude in the lower and middle troposphere.
(optics)
The angle between the plane of a photograph from a downward-pointing camera and the horizontal plane.

tilt

i. The angular movement of the offset of a camera axis about an aircraft's longitudinal axis.
ii. The angle at the perspective center between the photograph perpendicular and the plumb line or another exterior reference direction. In aerial photography, the tilt may be separated into the component angles, referred to as the fiducial axes, with the axis one, or more nearly, in the direction of flight. In an aerial camera orientation, a tilt in the direction of the x-axis is known as a j phi) tilt, and one in the direction of the y-axis is known as an ω (omega) tilt.
