Airline passengers see a smiling face greet them at the door, their boarding pass is checked to make sure they are on the correct flight, and they're pointed in the direction of their seat. However, the flight attendants have already been busy with their duties prior to the flight. These are absolutely essential tasks that take place every flight and are critical to flight safety. Passengers often never see the safety side of things, thinking that we are there only as servers, which could not be further from the truth. Flight attendants are responsible for passengers' safety and comfort, with safety always the priority. This list explores five of the most important safety duties flight attendants do that passengers would never notice. (Please be aware that procedures may vary slightly depending on the airline and the aircraft variant). Checking The Safety Equipment An important task prior to every flight Credit: MedAire Before boarding starts, a security check takes place to ensure that nothing is out of place or unusual. Then the flight attendants confirm that emergency equipment is on board and working. They test the emergency lights, evacuation alarm, and public address system. The defibrillator must be working and is checked by the visible or flashing light. They also check that all items are in the manual safety demonstration kit and that spare safety cards, life vests, infant life vests, and infant rafts are available. Seatbelts are checked for any defects. The megaphone is also tested, and crew members must check that a fire containment bag is onboard. The oxygen bottles are checked to ensure they are valid and more than 3/4 full. Halon or BCF fire extinguishers must have a pin in place and be in the green zone. The lavatory smoke detectors and waste bin fire extinguishers have to be free from obstruction and working. Life rafts have to be in place where carried, as well as the ELT (Emergency Location Transmitter), which should be armed. Slide pressure gauges are also checked. Extension seat belts and infant seatbelts need to be available. A flight attendant checks that their own jumpseat works and the harness fits, and that every piece of safety equipment at their station is in place and ready to use. This includes that the smoke hood (PBE) is sealed but ready to use, and the fire gloves are in place. The crew life jacket should be sealed and under the crew seat. There is usually a manual release tool to release the oxygen masks if deployment fails. The flashlight should be checked to ensure the red light is blinking. Galley checks are also completed to ensure everything is safe, serviceable, and secure. Identifying Able-Bodied Passengers Ready in case of an emergency Credit: Airbus As passengers board, flight attendants are quietly looking for able-bodied passengers, or ABPs, who could help in an emergency. These are usually people like law enforcement officers, military personnel, or firefighters. Off-duty pilots or cabin crew who already know the drill are perfect ABPs and can evacuate the aircraft if necessary. Boarding can be the most stressful part of the job, since the flight attendants are also dealing with seating problems, lost boarding passes, oversized bags, and blocked aisles. Doctors and medical practitioners are also noted, as they may be able to help in a medical emergency or post-evacuation. ABPs can be tasked with things in an evacuation like helping people off the end of the slide and leading them away upwind from the aircraft. They may be asked to hold up the end of a deflated slide so it remains usable in an evacuation. ABPs can be shown how to operate a door in a pre-planned emergency if a crew member is incapacitated and unable to operate the exit. Those passengers seated next to an emergency exit are briefed on how to operate it. Exit rows have their own rules: in the US, passengers there must be over 15, able to understand commands, physically able to help, and not responsible for anyone else on board, such as a young child. In the UK, we have other considerations too, as exit rows are restricted. We use the acronym CODPIES to check who is not allowed to sit in an exit row: Children, Obese, Deportees, Pregnant, Infant, Elderly, Sick. (This can vary at different airlines). Arm The Doors & Cross-Check A critical event just before taxiing Credit: Yusia 13 | Shutterstock When the pilots call to "arm the doors and cross-check," each flight attendant uses the arming lever to set their door, so the escape slide will deploy automatically if it is opened. Sometimes the command is different depending on the airline: some use "doors to automatic and cross-check." The crew member at the opposite door then checks it and confirms aloud, "armed and cross-checked," and all doors are reported to the senior crew member. The cross-check reduces the chance of a mistake, and the process is reversed after landing. On Airbus aircraft, such as the Airbus A320 family, the arming lever is secured with a safety pin and operates with a pin-lever-pin process, whereas on Boeing aircraft it works differently. On the Boeing 737, for example, the slide is manually attached to the floor by the cabin crew physically attaching the girt bar to the bracket on the floor and a flag being placed across the window. Many modern Boeing mainline doors use different mechanical configurations for slide arming that do not rely on a separate removable safety pin in the same manner. Disarming the doors takes place just as the aircraft comes to a stop, and the doors are returned to manual mode and again cross-checked. This is just as important as arming the door, as blowing a slide on the jetbridge can cause injuries to ground staff. The command is "disarm doors and cross-check" or "doors to manual and cross-check", depending on the airline. It is a strict procedure not to open the door until the steps or the jetbridge are in place and ground staff knock on the window with a thumbs-up sign. You can read more about this procedure in detail in another Simple Flying article. The Silent Review For focus and preparation, should an evacuation occur Credit: Wizz Air Once seated for takeoff and landing, flight attendants mentally rehearse their emergency procedures and duties, in what's called the silent review or 30-second review. They go through their evacuation commands in their head, the safety equipment nearby, and assess the conditions outside. They also assess the nearest available exits, in case their exit is blocked, and which passengers might need extra help in their area. Many airlines use memory aids, such as one where E stands for equipment available, L for the location of equipment, and A for able-bodied passengers. Some airlines use ALERT: Aircraft type, Location of exit, Equipment required, Responsibility, and Threat. Another one is OLDABC: Operation of exit, Location of emergency equipment, Drills (brace for impact), ABPs and special assistance passengers, Brace position, Commands given during evacuation as noted by GlobalAir. Cabin crew usually avoid talking to passengers at these times, and they may sit in a partial brace position, a relaxed version of the emergency brace position, by sitting on their hands or holding the jumpseat according to AFAR, or with their hands on their knees and feet forward or back depending on which way the jumpseat is facing. The emergency brace position is different: head back, hands behind the head, elbows forward, and feet in the same position. Communication is key Credit: Wizz Air When a flight attendant picks up what looks like a standard phone, they're speaking to the pilots, the senior crew member, or other crew members over the aircraft's interphone or making an announcement. The cockpit door stays locked during flight and opens only when necessary, so this line is how the cabin and cockpit coordinate throughout the flight, including the all-important 'cabin secure' checks before takeoff and landing. The number of chimes tells us who is calling us, and we need to pick up the call as soon as possible. It may be the flight crew warning us of turbulence ahead or the senior checking on service flow. It may be an individual call to one door, but it is often an "all crew" call so the flight deck or the senior can speak to everyone at the same time, and then we all report back to the senior by our door position. On Airbus aircraft, cabin lights and chimes are managed by the Cabin Intercommunication Data System (CIDS) and displayed via overhead Area Call Panels (ACP). Airbus uses a layered, multi-tone musical chime system paired with specific colored lights to communicate between passengers, flight attendants, and the flight deck. There are also different chimes and lights that indicate if there is smoke in the lavatory or an emergency. For example, a single chime and a blue light mean that a passenger has pressed the call bell at their seat. A single chime with a yellow light means the call is from the lavatory. A high-low chime is a normal crew call.
