Where can fixed O2 masks with ICS be found in an aircraft?

Fixed oxygen masks with intercom systems (ICS) are typically located near the flight crew seats. This placement ensures that the pilots and other crew members can quickly access the masks in case of an emergency, where supplemental oxygen may be needed, such as during cabin depressurization. Having these masks readily available allows for effective communication among the crew while using the oxygen system, which is critical for coordinating responses during an emergency situation.

The other locations mentioned, such as baggage compartments, passenger overhead bins, or engine maintenance areas, would not provide the immediate access necessary for flight crew in emergency scenarios. Oxygen masks must be easily reachable from the cockpit to allow for a prompt response, so it is logical that they are located within arm's reach of the crew seats where the pilots operate the aircraft.
