How does a flight crew handle turbulence?

Turning on the seatbelt sign is the appropriate action for a flight crew to take during turbulence. This procedure alerts passengers and crew members to fasten their seatbelts to ensure safety throughout the turbulent period. It is a standard safety protocol to minimize the potential risk of injury from sudden movements or drops that can occur during turbulence.

The seatbelt sign serves as a communication tool to remind everyone onboard to secure themselves, as turbulence can be unpredictable in intensity and duration. The crew prioritizes passenger safety, and this action reflects that commitment.

In contrast, the other options may not effectively address the safety of passengers during turbulence. Accelerating the aircraft could be counterproductive, as it may increase the strain on the aircraft and does not guarantee a reduction in turbulence. Descending immediately is not the standard response unless instructed by air traffic control or if the turbulence endangers the flight, which is not typically the case. Lastly, ignoring turbulence, even if it seems mild, is not advisable, as it could escalate unexpectedly, catching passengers and crew off guard. Such practices could compromise safety rather than enhance it.
