All Singapore carriers will have to ensure that there are at least two people in the cockpit at all times, after a Germanwings co-pilot locked his captain out and crashed a plane on Tuesday.
Currently, there is no such requirement for Singapore Airlines, SilkAir, Jetstar Asia, Tigerair, Scoot and SIA Cargo.
The Civil Aviation Authority of Singapore has been discussing with all local carriers the implementation of the procedures aimed "to deter malicious acts" a spokesman told The Straits Times yesterday.
It is not clear when this will take effect.
In the wake of Tuesday's crash in the French Alps, which killed 150 people, the Singapore authority stressed that there are procedures and systems in place to ensure pilots are equipped to do the job.
Before a professional pilot licence is given, a person must be certified medically fit through an assessment based on global standards. Regular reviews are conducted every six months or once a year.
The medical assessments include a physical examination and psychiatric evaluation, the spokesman said.
Singapore carriers are required to have procedures to enable a pilot to report on a fellow pilot who, in the former's opinion, is not fit to fly.
They must also conduct security training programmes for all crew members to teach them how to deal with a colleague or passenger who could pose a risk.
