A signal strength and readability report is a standardized format for reporting the strength of the radio signal and the readability (quality) of the radiotelephone (voice) or radiotelegraph (Morse code) signal transmitted by another station as received at the reporting station's location and by their radio station equipment. These report ...
Point in a direct approach where a 3º normal visual descent can be started to achieve a safe landing and stabilized approach to the RWY - VDP (in distance) = HAT (height over terrain) / 300 (HAT is the height of the MDA read in the approach chart of the AD) VDR VHF digital radio VFO Variable-frequency oscillator: VFR visual flight rules: VG
The S stands for "Strength". Strength is an assessment of how powerful the received signal is at the receiving location. Although an accurate signal strength meter can determine a quantitative value for signal strength, in practice this portion of the RST code is a qualitative assessment, often made based on the S meter of the radio receiver at the location of signal reception.
The NORAC rule book illustrates all signal aspects and indications which may appear on track operated by member railroads. However, GCOR does not illustrate signal aspects and indications because of the lack of uniformity between the participating railroads. Signal aspect and indication illustrations instead appear in each railroad's system ...
Examples of police codes include "10 codes" (such as 10-4 for "okay" or "acknowledged"—sometimes written X4 or X-4), signals, incident codes, response codes, or other status codes. These code types may be used in the same sentence to describe specific aspects of a situation. Codes vary by state, county, and agency.
Signals are most commonly mounted on trackside masts about 12 to 15 feet (3.7 to 4.6 m) high to put them in the eyeline of the engineer. Signals can also be mounted on signal bridges or cantilever masts spanning multiple tracks. Signal bridges and masts typically provide at least 20 feet (6.1 m) of clearance over the top of the rail.
A regional transmission organization (RTO) in the United States is an electric power transmission system operator (TSO) that coordinates, controls, and monitors a multi-state electric grid. The transfer of electricity between states is considered interstate commerce, and electric grids spanning multiple states are therefore regulated by the ...
The RTO test is performed under the worst possible conditions; i.e. with fully worn out brakes, the plane loaded to maximum takeoff weight and no use of thrust reversers. During an RTO test most of the kinetic energy of the airplane is converted to heat by the brakes, which may cause the fusible plugs of the tires to melt, causing them to ...
