From the Flight Deck

Here's the second question which was not posted immediately in early October.

Q: Is there any way to detect and detour around turbulence? Ivan Chan, Vancouver

Air Canada’s policy is to avoid or circumnavigate known areas of significant turbulence, especially thunderstorms. On-board weather radar detects precipitation, which, if significant, implies turbulence. Modern airliners also have low-level wind-shear detection systems. No device detects turbulence due to jet streams, but weather maps depict and forecast all types of turbulence. Sometimes all it takes to ensure a smooth ride is for flight dispatchers to plan flights around areas of turbulence or at different altitudes.
