Some advanced avionics systems can integrate information from several systems in a single display. The display in Figure 5-26  presents the route programmed into the FMS, together with fuel predictions for each waypoint made by the fuel management function. 

## Chapter Summary 

In addition to primary flight instruments, advanced avionics (utilizing microchips) can also display landmarks, weather in real time or near real time, traffic, terrain, systems status (including fuel state) and endurance in, with, or next to the selected navigation route. None of these functions allows you to disregard the requirement “to see and avoid” traffic, obstructions, or hazardous weather. These options are designed to enhance safety—not to extend the limits of operations. 

In all cases, you must accurately determine what equipment is installed and authorized. You must know the limitations of the data presented and all of the details of the displays, especially refresh rates and delays from data acquisition to presentation. The onboard data is never an adequate substitute for a timely and thorough preflight briefing.
