The aviation transponder interrogation modes are the standard formats of pulsed sequences from an interrogating Secondary Surveillance Radar (SSR) or similar Automatic Dependent Surveillance-Broadcast (ADS-B) system. The reply format is usually referred to as a "code" from a transponder, which is used to determine detailed information from a ...
This is a partial list of awareness ribbons. The meaning behind an awareness ribbon depends on its colors and pattern. Since many advocacy groups have adopted ribbons as symbols of support or awareness, ribbons, particularly those of a single color, some colors may refer to more than one cause.
Transverse mode. A transverse mode of electromagnetic radiation is a particular electromagnetic field pattern of the radiation in the plane perpendicular (i.e., transverse) to the radiation's propagation direction. Transverse modes occur in radio waves and microwaves confined to a waveguide, and also in light waves in an optical fiber and in a ...
In track-while-scan mode the radar has the ability to acquire and lock/track multiple targets while simultaneously providing a view of the surrounding airspace, which in turn aids the pilot and or operator in maintaining better situational awareness.
VHF Data Link. The VHF Data Link or VHF Digital Link ( VDL) is a means of sending information between aircraft and ground stations (and in the case of VDL Mode 4, other aircraft). Aeronautical VHF data links use the band 117.975–137 MHz assigned by the International Telecommunication Union to Aeronautical mobile (R) service.
Sabbath mode. Sabbath mode, also known as Shabbos mode (Ashkenazi pronunciation) or Shabbat mode, is a feature in many modern home appliances, including ovens, [1] dishwashers, [2] and refrigerators, [3] which is intended to allow the appliances to be used (subject to various constraints) by Shabbat-observant Jews on the Shabbat and Jewish ...
An orthomode transducer ( OMT) is a waveguide component that is commonly referred to as a polarisation duplexer. Orthomode is a contraction of orthogonal mode. Orthomode transducers serve either to combine or to separate two orthogonally polarized microwave signal paths. [1] One of the paths forms the uplink, which is transmitted over the same ...
Sliding mode control. In control systems, sliding mode control ( SMC) is a nonlinear control method that alters the dynamics of a nonlinear system by applying a discontinuous control signal (or more rigorously, a set-valued control signal) that forces the system to "slide" along a cross-section of the system's normal behavior.
Ethanol fuel mixtures have "E" numbers which describe the percentage of ethanol fuel in the mixture by volume, for example, E85 is 85% anhydrous ethanol and 15% gasoline. Low-ethanol blends are typically from E5 to E25, although internationally the most common use of the term refers to the E10 blend. Blends of E10 or less are used in more than ...
Mode X is an alternative 256-color graphics display mode of the IBM VGA graphics hardware that was popularized by Michael Abrash. The primary advantage of Mode X is that it has square pixels: a resolution of 320 × 240 instead of the standard VGA Mode 13h which is 320 × 200. It is usually enabled by entering Mode 13h via an MS-DOS system call ...
