The correct answer is 15 minutes same distribution to each mask. This means that if all masks are used, the oxygen generator will provide oxygen for a total of 15 minutes, with an equal distribution of oxygen to each mask.

The correct answer is Purser station and pilot overhead panel. This means that the EVAC COMMAND switch can be found both at the purser station and on the pilot overhead panel. It is likely that these locations are easily accessible to both the purser and the pilot in case of an emergency evacuation.

When the master selector of the EVAC command panel is in the "CAPT" position and the purser presses his EVAC "COMD" pb, only the EVAC signals in the cockpit will be energized. This means that the evacuation signals, such as alarms or lights, will only activate in the cockpit area. The cabin area will not receive any EVAC signals in this scenario.

There are two escape ropes in the cockpit, with one located over each window. These ropes can be used through either the left or right window for emergency escape.

When the master selector of the EVAC command panel is in the "ALL" position, it means that the evacuation signals are activated simultaneously in both the cockpit and the cabin. This is done to notify and alert both the flight crew and the cabin crew to conduct an evacuation procedure. The activation of the evacuation signals ensures that everyone on board is aware of the emergency situation and can take appropriate action.

When the cabin altitude rises above 14,000 ft, the oxygen masks will drop out automatically. This is triggered by the combination of the cabin pressure and the action taken by the flight deck. The increase in cabin altitude indicates a decrease in oxygen levels, which can be dangerous for passengers and crew. Therefore, the oxygen masks are designed to deploy automatically to ensure that everyone has access to oxygen in such situations.

When the "EVAC COMMAND" switch is activated by the purser, the cockpit crew receives an emergency evacuation signal. This signal alerts the pilots to initiate the evacuation procedure, which involves notifying the cabin crew, deploying emergency slides, and sounding the evacuation chimes in the passenger cabin. The activation of the switch ensures that the cockpit crew is immediately made aware of the need for evacuation and can take the necessary actions to ensure the safety of all passengers and crew members.

In some situations, the captain may need to call all cabin attendants at the same time. This could be for various reasons such as providing important instructions or information, coordinating emergency procedures, or addressing a critical situation on the aircraft. It is essential for the cabin attendants to be readily available and responsive to the captain's communication in order to ensure the safety and well-being of the passengers on board.

A thermal discharge of the crew oxygen bottle is indicated by the green blow out disc missing. The blow out disc is designed to rupture and release the pressure in the event of a thermal discharge. If the green blow out disc is missing, it suggests that the disc has ruptured due to a thermal discharge, indicating a potential issue with the crew oxygen bottle. The other options do not provide any indication of a thermal discharge.

The EVAC signals are located in the cockpit and next to the forward left of the cabin door. This means that there are two locations where the EVAC signals can be found: in the cockpit and next to the forward left of the cabin door.
