How does the Longitude 700's weather radar assist in planning and real-time decisions?

• A. Detects precipitation/turbulence, informs route and altitude adjustments, supports avoidance planning
• B. Adjusts cabin lighting
• C. Controls fuel pumps
• D. Assist with navigation

Answer: (C)

Weather radar is used to see weather ahead and influence both planning and in-flight decisions. It detects precipitation and turbulence, and shows how those conditions are moving. With that information, you can plan routes and altitudes that avoid heavy weather, and you can make real-time adjustments as storms shift.

In planning, you’d look for areas with lighter precipitation or lower turbulence and choose a route and cruise altitude that minimize exposure to adverse weather. In flight, as radar echoes move, you can steer around cells, change altitude to find smoother air, and adjust speed to maintain safety and comfort.

The other options don’t fit the radar’s role. It doesn’t control cabin lighting or fuel pumps, and while radar data informs navigation decisions, its primary purpose is weather detection and avoidance rather than basic navigation control.
