Aviation Computer Based Training (CBT) Practice

Using the Emergency Escape Breathing Device (EEBD) immediately is crucial when smoke or toxins are detected in the air during flight. The EEBD is designed to provide a supply of clean air, allowing the crew or passengers to breathe safely in an environment that may contain harmful substances. This device is especially important in containing smoke inhalation and avoiding respiratory distress, which can occur rapidly when exposed to smoke or toxic fumes.

When smoke or toxic gases infiltrate the cabin, the priority is to ensure that individuals can breathe adequately while any necessary actions are taken to address the source of the smoke or toxins. Immediate usage of the EEBD helps to mitigate the risk of injury or incapacitation due to inhalation of harmful substances.

In contrast, the use of emergency beacons, turning off cabin lights, or preparing for landing may not directly address the immediate danger posed by smoke or toxins. These actions could be relevant in a broader emergency context but do not provide a direct solution for ensuring occupant safety in the presence of hazardous air quality.
