A Traffic Advisory (TA) symbolappears as a solid yellow circle. All other traffic is shown as a hollow white diamond.Altitude deviation from own aircraft altitude is shown above the target symbol if trafficis above own aircraft altitude, and below the symbol if they are below own aircraftaltitude. Altitude trend is shown as an up arrow (>+500 ft/min), down arrow (<-500ft/min), or no symbol if less than 500 ft/min rate in either direction.TIS-A Symbol DescriptionTraffic Advisory (TA)Other TrafficTIS-A Traffic SymbolsTIS-A ALERTSA TIS-A audio alert is generated whenever the number of Traffic Advisories on theaera 795/796 screen increases from one scan to the next. Limiting Traffic Advisoriesonly reduces the “nuisance” alerting due to proximate aircraft. For example, when thefirst Traffic Advisories appear on the TIS-A display, the user is alerted audibly. So longas a single aircraft remains on the TIS-A display, no further audio alert is generated. Ifa second (or more) aircraft appears on the screen, a new audio alert is sounded.
