Symbology And Displays

摘要

In many things, bigger is better. So it is with multi-function displays, moving maps and the like. Put simply, larger display sizes translate to more and better-organized information, with greater detail and clarity, especially in high-workload situations. The need for clear, unambiguous symbology in cockpits should be obvious. That's one reason industry and regulators have agreed on standard symbology when displaying airborne traffic information. The table below details the symbol shapes and colors used when depicting traffic in the cockpit, whether derived from TCAS I/I I, ADS-8's TIS-B service or TAS. However, some traffic technologies—notably early portable products—do not use this symbology, in part due to limited data on the potential conflict. Additionally, since only TCAS II provides RAs, you won't see a solid red square unless you're flying a TCAS ll-equipped aircraft.
