Which emergency equipment is commonly found in the cockpit?

The correct choice includes fire extinguishers, oxygen masks, and first aid kits because these items are critical for addressing safety concerns in the cockpit.

Fire extinguishers are essential for quickly combating any fires that may arise during flight, particularly since electrical equipment and flammable materials are present in the cockpit. Oxygen masks are vital for providing pilots with breathable air in the event of cabin depressurization, ensuring they can maintain consciousness and control of the aircraft. First aid kits are indispensable for treating injuries or medical emergencies that might occur during the flight, allowing the flight crew to provide immediate assistance until further medical help is available.

These items reflect the focus on immediate response to emergencies that could occur in the cockpit environment, ensuring that pilots have the necessary tools to handle critical situations effectively.
