Where are portable fire extinguishers located on the aircraft?

The placement of portable fire extinguishers on the aircraft is critical for ensuring the safety of both the crew and passengers. Extinguishers are essential in quickly addressing any fire hazards that may arise in different areas of the aircraft.

The identified locations in the correct answer – the cockpit, crew rest area, and cargo compartment – provide comprehensive coverage. In the cockpit, having an extinguisher allows pilots to deal with any fire emergencies that could occur during flight operations. The crew rest area is essential as crew members need access to safety equipment while off duty, ensuring they can respond promptly to a fire threat. The cargo compartment is vital because various flammable materials might be stored there, necessitating immediate access to an extinguisher in case of an incident.

The other locations presented in the other choices do not include all areas that are crucial for effective fire suppression in the aircraft, leading to incomplete safety measures. Therefore, the selection of cockpit, crew rest area, and cargo compartment covers essential locations where risk is present and aligns with safety protocols in aviation operations.
