WHAT'S HAPPENING IN THE FLIGHT DECK WHEN TURBULENCE STRIKES? Sometimes this is all it takes to ensure a smooth ride.' Flight dispatchers will plan for flights to avoid these areas or fly at different altitudes. No device detects turbulence due to jet streams, but weather maps depict and forecast all types of turbulence. These do not detect high-level wind shear. He adds: 'Most airliners also have wind shear systems to detect shearing winds near the ground. A zero or one means things should be smooth, but when numbers three, four and five appear, the seat belt sign is likely to be illuminated.' 'My flight plan assigns a number from zero to nine to each navigation point along the route. Everyone is striving to deliver the smoothest ride possible. 'Our flight plan also assigns a numerical value for possible bumps along every waypoint, while flight dispatch sends us in-flight reports via datalink. These "heartbeats" show the whereabouts of the airplane, its altitude, and whether bumps occurred during the flight.
We can also interrogate other airplane reports from this site. A pilot's iPad can now superimpose a specific routing on weather charts that depict areas of bumps. Veteran Air Canada Dreamliner captain Doug Morris (above) offers a glimpse inside the cockpit during turbulence in his fascinating book This Is Your Captain SpeakingĬaptain Morris writes in This Is Your Captain Speaking: 'Technology has certainly helped to contend with the unpredictable nature of bumpy rides.
