What should be done if smoke is observed on the flight deck during descent?

If smoke is observed on the flight deck during descent, engaging emergency procedures and discussing the situation with the crew is essential for ensuring safety. This coordinated response is critical because smoke can indicate a serious issue, such as a fire or equipment malfunction, which requires immediate and organized action.

Following emergency procedures means that the crew will systematically address the situation, which could involve checking the sources of smoke, assessing the situation, and preparing for potential evacuations or other necessary actions. Communication with the crew is vital, as it allows all members to be informed about the situation and work together to ensure that both the aircraft and passengers are safe.

In contrast, simply descending to a lower altitude might not resolve the issue if there is an active fire or electrical source contributing to the smoke. Turning off all electrical systems could be dangerous and could lead to loss of vital instruments. Waiting to see if the smoke dissipates fails to address the urgent nature of the situation and could compromise safety.
