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.
Track-while-scan ( TWS) is a mode of radar operation in which the radar allocates part of its power to tracking a target or targets (up to forty with modern radar) while part of its power is allocated to scanning. It is similar to but functions differently in comparison to its counterparts range-while-search (RWS), long range search (LRS), air ...
Text mode increases in-camera sharpening to allow to photograph texts. Portrait mode widens the aperture to throw the background out of focus (see Bokeh). The camera may recognize and focus on a human face. Night portrait modes use an exposure long enough to capture background detail, with fill-in flash to illuminate a nearby subject.
A Mode 5 warning in EGPWS alerts the pilots if they descend below the glideslope during a landing approach. Evolution to EGPWS & TAWS. After these rules were issued, advances in terrain mapping technology permitted the development of a new type of ground proximity warning system that provides greater situational awareness for flight crews.
You get two modes for awareness, a simple ambient awareness mode that's programmed to a tap of the left bud by default, and a separate "TalkThru" mode you can access in the app or from the case.
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 ...
A traffic alert and collision avoidance system ( TCAS, pronounced / tiːkæs /; TEE-kas ), is an aircraft collision avoidance system designed to reduce the incidence of mid-air collision (MAC) between aircraft. It monitors the airspace around an aircraft for other aircraft equipped with a corresponding active transponder, independent of air ...
The neural correlates of consciousness ( NCC) are the minimal set of neuronal events and mechanisms sufficient for the occurrence of the mental states to which they are related. [2] Neuroscientists use empirical approaches to discover neural correlates of subjective phenomena; that is, neural changes which necessarily and regularly correlate ...
