What are self-help exits and who can be allocated these seats? Some aircraft are equipped with emergency exits located at the wing areas of the aircraft, also known as overwing emergency exits or self-help exits. These type of emergency exits may not be manned. Only passengers who appear capable of operating and/or are willing to assist with the operation of the exit can be allocated the seats at self-help exits and they will receive a safety briefing on the exit operation before the take-off.For more information, please refer to the Air Operator Certificate Requirements. 2. Why are there differing conditions for the usage of Portable Electronic Devices (PEDs) across different airlines? Passengers are permitted to use PEDs on board the aircraft. However, airlines may apply a more restrictive policy on the use of PEDs and the permissible times, conditions and limitations of use. For further information on the regulations, please refer to the Air Operator Certificate Requirements (Chapter 7 Paragraph 2.8).The usage of PEDs onboard is generally safe on most aircraft types as verified by aircraft and PED manufacturers who have performed analysis on their usage. Before airlines may allow the usage of PEDs, they must confirm that their aircraft can safely handle interference from PEDs. Medical PEDs such as Automated External Defibrillators (AEDs), Portable Oxygen Concentrators (POCs) and positive airway pressure devices (such as CPAP, BiPAP, etc) may be permitted for all phases of flight. You are advised to check with your airline before you travel. Passengers are advised to pay attention to the airlines' on-board announcements for instructions and limitations on the use of PEDs. Information on the airlines' PED policy may also be found in their safety information cards, in-flight magazines and on their website. 3. Are passenger safety briefings similar for all aircraft types? Passenger safety briefings may be similar in the compulsory topics that must be covered in the briefing but information will vary from one aircraft type to another. Therefore, it is important to pay attention to the passenger safety briefing for every flight.You may find more information on Passenger Safety Briefing in Air Operator Certificate Requirements (Chapter 7 Paragraph 3.1). 4. What is the correct bracing position for an emergency? The bracing position will be dependent on the seat location. Passengers should always remember to keep their seat belt fastened, the seat back upright and the tray table, video screen and foot-rest stowed.Passengers are advised to pay attention to the safety instructions given by cabin crew, and practise the brace method as directed. If in doubt, always ask for guidance or refer to the airlines' safety briefing card. Airlines in Singapore are required to provide information on the correct bracing method for passenger guidance in the safety briefings and/or safety information card. Always review the bracing methods before each take-off and landing, taking note of the following general guidelines:For seats with ample leg room (seat or partition in front of you is beyond reach): Sit as far back as possible; Place feet together flat on the floor as far back toward the seat as possible; Lean forward as far as possible with your chest as close as possible to the knees; Place hands on top of hear or wrap arms around or behind legs; and Always keep your head as low as possible and always remain in bracing position until directed otherwise by the cabin crew membersFor seats with limited leg room (seat or partition in front of you is within reach):Sit as far back as possible; Place feet together flat on the floor as far back toward the seat as possible; Lean forward as far as possible; Bring head towards seatback of the seat in front or any sturdy partition that may be in front of your seat; Place hands on top of one another and on the top of your head or either on top of the seat in front or against the sturdy partition; Cradle head in folded arms, keeping the arms as close as possible to the sides of your face; and Always keep your head down and cradled in your arms and always remain in bracing position until directed otherwise by the cabin crew member.These are general bracing techniques. Airlines' cabin crew, when required, will provide detailed guidance to passengers on the bracing methods, bearing in mind the specific needs of some passengers' e.g. pregnant mothers or mothers with infants. 5. What are the penalties for smoking in an aircraft? Smoking is strictly prohibited on Singapore-registered aircraft. Passengers, if found guilty, could face a fine (not exceeding $100,000) or imprisonment (not exceeding 5 years) or both. Passengers are also reminded that the use of e-cigarettes is also banned from use on all Singapore registered aircraft.You may find more information in the Air Navigation Order (Paragraph 80(6)). 6. What are the safety regulations in place for toddlers onboard? For the safety of toddlers, during the following phases of flight (taxi, take off and landing) and turbulent weather: Toddlers below the age of two are to be properly secured in a child restraint device; and Toddlers aged two years and above are to be properly secured in their seats by safety belts (with diagonal shoulder strap, where required to be carried) or safety harnesses. You are also advised to check with the airlines if you require more information on the types of child restraint systems. 7. Are airlines allowed to leave the seats at overwing emergency exits/self-help exits empty? Primary exits are the floor level exit doors manned by the cabin crew. Overwing emergency exits (also known as self-help exits) are exits that are not at floor level. They are alternative exits which can be used if there are passengers (briefed by the cabin crew on the operation of the exit) seated adjacent to them. In line with international practice, these exits are not required to be manned. Airlines have the discretion to manage the seating of their passengers at such exits as long as they meet CAAS' requirements.More details can be found in the Cabin Safetypage of the CAAS website or the Air Operator Certificate Requirements (Chapter 7 Paragraph 2.2 and 2.3). 8. Am I allowed to place luggage exceeding 10kg in the overhead compartment (for budget airlines)? The weight limit of hand luggage that can be carried into the cabin by each passenger is set by the airlines. However, the total weight of the hand luggage within each luggage compartment, must not exceed the weight limits of the compartment. CAAS requires airlines to ensure that loading instructions and training be provided to its staff on ensuring that weight limitation of each overhead compartment are adhered to; and how the hand luggage are to be stowed such that emergency exits and aisles are kept clear. You are advised to check with your airlines on the weight limit of your hand luggage.For more information, please refer to Air Operator Certificate Requirements (AOCR) (Chapter 7 Paragraph 2.5). 9. Why must window shades be kept open during taxi, take-off and landing? Window shades are required to be kept open during taxi, take-off and landing for the following reasons: To allow cabin crew a quicker and clearer view of the developing conditions and/or dangers outside the aircraft during an emergency. To allow passengers a clear view of what is happening outside the aircraft:so as to quickly alert the crew members, should they notice an emergency or anything out of the ordinary, (e.g. sparks coming out of the wing area, fuel leaks, fire in the engine, snow build-up on the wings, etc.) so as to have a better awareness of what is happening outside the aircraft during an emergency and be able to better orientate themselves, keeping clear of danger. To allow rescuers, in an emergency, to clearly see the inside of the aircraft cabin so that they can better assess the overall situation. 10. Why must lifevests be inflated just before exiting the aircraft during an emergency landing on water? There are several reasons why lifevests are to be inflated just before exiting the aircraft: Inflating life vests within the cabin will create hindrances and slow down the evacuation of passengers during an emergency. Passengers may not be able to manoeuvre through smaller emergency overwing exits with their inflated life vests. Also, the life vests may also become damaged in the process and will not be able to serve their purpose in water. Inflated life vests are also very stiff and will keep passengers' necks in an upright position, impeding their ability to brace on impact. If a cabin becomes engulfed with rising water during an emergency landing on water, passengers may become trapped inside a cabin as an inflated lifevest will prevent a passenger from being able to dive underwater to reach exits. 11. What items are permitted for carriage on board an aircraft? The list of items that can be carried on board an aircraft can be found on the CAAS website or the respective airlines' websites. Some examples of items permitted for carriage are as follows: Portable medical and electronic devices such as cameras, mobile phones, laptops, tablets such as iPads.Spare lithium batteries (including power banks) for electronic devices. Passengers are not allowed to carry more than two and they must be individually protected to prevent short circuits. Toiletries and cosmetics such as hair sprays, perfumes and medicines containing aerosols, alcohol or liquids, provided that each container does not exceed 100ml and the total quantity in all the containers does not exceed 1 litre. All the containers should be placed in a transparent re-sealable plastic bag which must be completely sealed. For more information, you may refer to the guidance provided by the Changi Airport GroupAlcoholic beverages in retail packaging and which do not exceed 70% alcohol by volume.
