This research aims at investigating the perceptions towards safety knowledge and skills and perceived efficacies among flight attendants onboard. Many studies have reported deficiencies in vocational training among flight attendants to handle specific onboard emergencies, but these findings are not surprising as knowledge and skills that are not put into active use have been shown to deteriorate or decay significantly even over very short intervals. To further understand the issue, an In-flight Safety Assurance Model is presented and data were collected and analyzed following this model. The findings revealed low perception and efficacy levels which highlight the need to establish Continuous Professional Development programs through making use of educational technology and multimedia.
