FAQ

Q1. What are the requirements of the carriage and use of power banks on aircraft?

In accordance with Aeronautical Circular No. AC/AGA/013R02 — "Restrictions on Dangerous Goods" published by the Civil Aviation Authority, passengers must comply with the specific requirements for the carriage of products with lithium batteries on aircraft. For details, please refer to the “Security Control Articles” under the “Public and Passenger Guide" on the AACM Official Website via https://www.aacm.gov.mo/.


In addition to the above legal requirement, airlines may impose additional restrictions on the carriage and use of power banks on aircraft based on safety considerations and operational measures. Therefore, passengers are advised to check with their airline for the latest requirements before traveling.

Q2. What proper checks should a passenger carry out on the lithium batteries when packing them for travel?
Passengers play an important role in ensuring aviation safety. Therefore, it is advisable that a passenger make the following safety check when packing lithium batteries before traveling.
 
Checklist Attention
  • Check if the lithium batteries have any visible defects
When lithium batteries exhibit physical damage, such as swelling or deformation, their structural stability and electrical insulation are not compromised, which may pose a major safety hazard.
  • Check if the lithium batteries are overheating
If lithium batteries experience abnormally high temperatures or make squeaking sound while charging, or if there are signs of aging or melting at the charging interface, this indicates potential safety concern. When lithium batteries reach overheating conditions, this may lead to fires or explosions, posing significant safety risks to both users and the surroundings.
  • Ensure proper storage of lithium batteries
Lithium batteries must be protected from external forces such as impact, puncture, or extrusion during storage or transportation, which may cause deformation or internal layer damage, increasing the risk of overheating incidents.
  • Ensure lithium batteries comply with carry-on requirements
 
All passengers must comply with specific requirements when carrying lithium batteries on flights. These include restrictions on the capacity of lithium metal or lithium ion batteries of different electronic devices. Also, all batteries must have a label indicting the voltage and the watt-hour rating.

Q3. According to the Air Navigation Regulation of Macau, do passengers need to switch off electronic devices throughout the entire flight?

In accordance with the Air Navigation Regulation of Macau which was approved by Executive Order No. 62/2016, before the aircraft takes off on any flight, the captain or the cabin crew member (in the name of the captain) should notify passengers that during certain stages of the flight, the use of any products or electronic devices that can possibly endanger the safety of the flight is prohibited.


The airlines incorporated in Macao have devised their company policy and their operational guidelines in accordance with the above requirement. To ensure that communication between the aircraft and the air traffic control tower will not be interfered with by other signals, the airlines will request passengers to switch off all electronic devices, during take-offs and landings.  During en-route, when a passenger needs to use an electronic device, the cabin crew member will indicate permission or prohibition according to the company policy and the operational guidelines. It must be pointed out that different airlines will have different policies and guidelines. Some airlines allow passengers to use electronic devices as long as it is not during a take-off or a landing; some airlines will impose restrictions on the use of electronic devices, e.g. phones must be turned to the flight mode. It is therefore advisable that wherever the flight is taken, passengers should ask the cabin crew member about the use of electronic devices if they need to use them.


In Macao (Note), if a passenger does not obey to the cabin crew member on the prohibited use of electronic devices, the passenger is considered to have violated No. 3), Provision 1, Article 4 of Administrative Regulation No. 31/2003. The captain of the flight can impose necessary measures on the passenger in accordance with the powers given to him/her by Article 5 of the same Regulation.


Note: The scope of applicability includes passengers who take the flight of a Macao registered aircraft, passengers who take the flight of an aircraft leased in by a Macao incorporated airline, or passengers who take the flight which originates from or is destined to Macao.
