MIL-HDBK-1908B
Overall layout drawings acq. System design drawings which include but are not limited to: (1)
the configuration and arrangement of major items of equipment for manned stations, such as a pilot's or astronaut's station, or launch control officer's station, or shipboard command station; (2) the configuration and arrangement of items of equipment, such as modular rack or maintenance ground equipment, which may not be a part of a manned station for operation, but require human access for maintenance; (3) the arrangement of interior lighting for operating or maintaining the
equipment; and (4) labels identifying general panel content, e.g., flight mission panel, countdown status panel, communications panel, or malfunction status panel.
Page uci. The data appearing at one time on a single display screen. Can also refer to standard keyboard keys used to move from one "page" of data to another or to the process of accomplishing this action.
Panel gen. The front face of an assembly, normally used for mounting controls and displays.
Panel layout drawings acq. Equipment detail drawings which include, but are not necessarily limited to: (1) a scale layout of the controls and displays on each panel or an item of equipment, such as an astronaut's, pilot's or launch control officer's console; (2) a description of all symbols used; (3) identification of the color coding used for displays and controls; (4) the labeling used on each control or display; and (5) the identification of control type (e.g., alternate action or momentary) and a clear differentiation between controls and indicators.
Panning uci. An orientation of display framing in which a user conceives of the display frame as moving over a fixed array of data. The opposite of scrolling.
Part acq. One piece, or two or more pieces joined together which are not normally subject to disassembly without destruction of designed use, (Examples: outer front wheel bearing of a 3/4 ton truck, computer chip, composition resistor, screw, gear, mica capacitor, audio transformer, milling cutter.)
Peak A-weighted sound pressure level snv. The A-weighted sound pressure level measured by a peak reading sound level meter or a combination of instruments with equivalent characteristics, such as a sound level meter and an impact meter, or a sound level meter and a calibrated oscilloscope, where
the sound level meter has a peak sound pressure level measuring circuit with total rise time of 200 microseconds or less.
Peak-clipping (of speech signals) snv. A technique for controlling amplitude relationships in speech by limiting the excursions of instantaneous peak-amplitudes to improve intelligibility of speech, usually followed by amplification of the signal to increase the amplitude of the clipped peaks to their original level, with proportional increase of the weaker speech sounds.
Peak pressure level snv. The highest level, in dB, achieved. (Peak pressure is the highest level, in Pa, achieved). Conversion between either kPa or psi and dB is shown in Figure 3. The reference pressure is 20 µPa (peak). (See dBP)
Personal hearing protection snv. Personal protective equipment (e.g., helmets, headsets, earmuffs, earplugs, or other approved protective equipment) that attenuates ambient noise levels in the ear canal.
Phonetically balanced (PB) monosyllabic word intelligibility test snv. See "Speech intelligibility."
Pointer dsi. A transmittable symbol under the direct control of the operator, used to point to displayed information, for highlighting or identifying areas of interest.
