Aircraft Safety and Cabin Operations

A bar that secures an escape slide to the floor brackets.

The process of removing the girt bar and preparing an escape slide for deployment.

The handle that inflates an escape slide manually.

The process of deploying an escape slide by opening the door and pulling the manual inflation handle.

An emergency situation where an aircraft lands on water instead of land.

The center point of the aircraft's weight distribution

The maximum permitted weight of an aircraft, including passengers, cargo, and fuel.

The position of the escape slide when ready for immediate deployment.

Opening the aft doors of an aircraft during a ditching can significantly reduce its ability to float, making it dangerous.

The overwing exits provide sufficient escape options in case of a ditching, even if the aft doors are not used.

The escape slide is detached from the aircraft using a handle, but is initially connected by a mooring line.

The mooring line automatically disconnects if the aircraft sinks to prevent damage to the slide.

If the total weight of passengers, especially those requiring assistance, exceeds 350 lbs (159 kg), the mooring line will snap.

In an emergency evacuation, passengers should use the escape slides as flotation devices after they are turned upside down.

Passengers, particularly those with special needs, can use the escape slides as flotation devices, but the maximum weight must be below 350 lbs (159 kg).

The system allows passengers to call for an attendant using a button located on the Passenger Service Unit (PSU). Pushing the button illuminates a light on the PSU and at the master call light panel, and sounds a chime.

Located on the inboard wall near the lavatory sink, this system allows passengers to request assistance from an attendant. The call is indicated by an illuminated light on the lavatory door and at the master call light panel, along with a chime.

Kitchens in the aircraft's cabin. Galleys provide space for storing and preparing food and beverages for passengers.

Removable units that hold food, beverages, or waste for the galley. They are typically latched into the galley units.

Galleys may be equipped with electrical power and water services. The water is supplied from the pressurized water system of the aircraft.

In an emergency, the water supply to the galleys can be shut off, potentially interrupting the water flow for food service and hygiene.

This is the procedure for exiting an aircraft using the over-wing exit. It involves pushing a panel inwards, allowing the exit door to open automatically upwards.

These straps are used to close the over-wing escape doors on an aircraft, ensuring its security.

These ropes are found inside the upper frames of aft over-wing exits on the B737-800. They're used as a handhold for passengers to navigate over the wing in a ditching situation.

Emergency escape ropes are attached to the exit frame and stowed in a tube inside the cabin ceiling. They're pulled free and attached to a D-ring on the wing for passenger guidance in a ditching situation.

Cabin crew stations are located at the front, rear, and aft service entry doors of the B737-800. These stations include jump seats with a combination seat belt and shoulder harness.

The jump seats at cabin crew stations on a B737-800 are designed to retract automatically when not in use. Each seat includes a combination seat belt and shoulder harness with a single point release mechanism.

The shoulder harness on jump seats is adjustable and retracts into a stowed position when not in use. It has a release plate that needs to be turned 90 degrees to unlock the harness.

A combination seat belt and shoulder harness with a single-point release is integrated into the jump seats at cabin crew stations. The shoulder harness can be adjusted and retracted when not in use.

A system that provides clean water for the galley and lavatories.

A valve that shuts off the water supply to the galley and lavatories. It can be used to prevent water from getting all over the place.

An electrical switch in the flight deck that controls the power supply to the galley. It needs to be "ON" for the galley to have power.

A safety feature that automatically cuts off the galley's electrical power in case of a generator failure.

A panel located in the galley that contains circuit breakers for the oven and water heater.

A power outlet located in the galley that is used by cleaners only.

A container in the galley that is used to collect trash.

A sink in the galley that is only used for cleaning. Liquids and solid waste are not allowed to be disposed of in the sink.

The process of safely exiting an aircraft through the second window in an emergency situation.

These seats are adjustable for comfort and safety.

This seat is located in the aisle in front of the flight compartment door and can be folded up when not in use.

The pilot seats are adjustable for comfort and safety. The controls for adjustment include H, V, R, and T.

The flight crew is responsible for communicating the safety features and procedures of the observer seat to the occupant.
