21Visual Approach Slope Indicator — The Visual Approach Slope Indicator (VASI) is a system of lights on the side of an airport runway that provides visual descent guidance information during the approach to a runway. These lights may be visible from up to eight kilometers (five… …
22Translabyrinthine approach — The translabyrinthine approach is a surgical approach to the cerebellopontine angle, or CPA. It is used in the surgical extirpation of lesions of the cerebellopontine angle, including acoustic neuroma.The translabyrinthine approach was developed… …
23final approach segment — The segment of an instrument approach procedure in which the alignment and descent for landing are accomplished (ICAO). It begins at the final approach fix and ends at the missed approach point. The final approach can be to a runway for a… …
24abbreviated visual approach slope indicator system — A night landing aid placed at the beginning of a flare path or runway. It displays different colored lights, depending on the angle from which it is viewed by a pilot approaching to land. When viewed from the correct angle of safe approach, it… …
25Helix angle — In mechanical engineering, a helix angle is the angle between any helix and an axial line on its right, circular cylinder or cone. [ANSI/AGMA. ANSI/AGMA Standards 1012 G05 Gear Nomenclature, Definitions of Terms with Symbols. American Gear… …

27Ligand cone angle — The ligand cone angle (also known as the Tolman cone angle or θ) is a measure of the size of a ligand. It is defined as the solid angle formed with the metal at the vertex and the hydrogen atoms at the perimeter of the cone (see figure). Tertiary …
28Clock angle problem — The diagram shows the angles formed by the hands of an analog clock showing a time of 2:20 Clock angle problems are a type of mathematical problem which involve finding the angles between the hands of an analog clock. Questions of this nature may …
29initial approach segment — The segment of an instrument approach procedure between the initial approach fix and the intermediate approach fix or, where applicable, the final approach fix or point (ICAO). In the initial approach, the aircraft has departed the en route… …
30area navigation (RNAV) approach configurations — The approach configurations for area navigation are the standard T, modified T, standard I, and terminal arrival area. i. Standard T. An RNAV approach whose design allows direct flight to any one of three initial approach fixes (IAF) and… …
