TEMPO.CO, Jakarta - The international commercial aviation industry in this modern era has set a strict rule on items that are permitted and banned from entering an airplane's cabin. Other than the obvious ban on sharp objects, liquid substances in containers is also a target of the regulation.
Back in Indonesia, the limit on the liquid substances is regulated under the Air Transport Director General's Decree No. SKEP/43/III/2007 on liquid, aerosols, and gels, passengers carry into a commercial airplane’s cabin.
Article 2a and 3 (1) states that the three liquid items kept in containers permitted inside an airplane's cabin are limited to a maximum of 100-millimeter containers.
Meanwhile, liquid stored in containers bought or originated from an airport's duty-free store, might be carried on board as long as it is limited to 1,000 ml and must be re-sealed.
This regulation is tightly linked to the history of terrorism, which according to Angkasa Pura's Instagram account, is sparked by a terror plot in August of 2006 for an international route to London, United States, and Canada.
