The gun sight is adjusted up by 0.94 mil or 3.2' in order to compensate for the bullet drop. The gunsights are usually adjustable in unit of 1 ⁄ 2 minutes, 1 ⁄ 4 minutes of angle or 0.1 milliradians.
Geodetic latitude and geocentric latitude have different definitions. Geodetic latitude is defined as the angle between the equatorial plane and the surface normal at a point on the ellipsoid, whereas geocentric latitude is defined as the angle between the equatorial plane and a radial line connecting the centre of the ellipsoid to a point on the surface (see figure).
Limits of Stability (LoS) are a concept in balance and stability, defined as the points at which the center of gravity (CoG) approaches the limits of the base of support (BoS) and requires a corrective strategy to bring the center of mass (CoM) back within the BoS. [1] In simpler terms, LoS represents the maximum distance an individual can ...
The horizontal coordinate system is a celestial coordinate system that uses the observer's local horizon as the fundamental plane to define two angles of a spherical coordinate system: altitude and azimuth. Therefore, the horizontal coordinate system is sometimes called the az/el system, [1] the alt/az system, or the alt-azimuth system, among
Pressure altitude is the elevation above a standard datum air-pressure plane (typically, 1013.25 millibars or 29.92" Hg). Pressure altitude is used to indicate "flight level" which is the standard for altitude reporting in the U.S. in Class A airspace (above roughly 18,000 feet).
A pylon turn is part of a maneuver also known as "long-line loiter" [1] which can be used to deliver messages or packages by plane without needing to land. In this maneuver it is possible to lower a bucket on a line to the ground in such a way that the bucket remains stationary on the ground, permitting transfer of material.
In astronomy, the altitude in the horizontal coordinate system and the zenith angle are complementary angles, with the horizon perpendicular to the zenith. The astronomical meridian is also determined by the zenith, and is defined as a circle on the celestial sphere that passes through the zenith, nadir, and the celestial poles .
