===Weather systems===
{{Main|Weather radar|Lightning detector}}
Weather systems such as [[weather radar]] (typically [[Arinc&nbsp;708]] on commercial aircraft) and [[lightning detector]]s are important for aircraft flying at night or in [[instrument meteorological conditions]], where it is not possible for pilots to see the weather ahead. Heavy precipitation (as sensed by radar) or severe [[Clear-air turbulence|turbulence]] (as sensed by lightning activity) are both indications of strong convective activity and severe turbulence, and weather systems allow pilots to deviate around these areas.

Lightning detectors like the Stormscope or Strikefinder have become inexpensive enough that they are practical for light aircraft. In addition to radar and lightning detection, observations and extended radar pictures (such as [[NEXRAD]]) are now available through satellite data connections, allowing pilots to see weather conditions far beyond the range of their own in-flight systems. Modern displays allow weather information to be integrated with moving maps, terrain, and traffic onto a single screen, greatly simplifying navigation.

Modern weather systems also include [[wind shear]] and turbulence detection and terrain and traffic warning systems.<ref name="four">{{cite news
