A majority of aviation professionals do not expect airline safety to improve during the next five years. According to the results of the survey of over 140 aviation industry professionals, 56% feel that the level of airline safety will stay the same or worsen over the near to medium term. The survey was conducted by Ascend, a London-based aviation consultancy. The Ascend survey asked industry insiders to identify the biggest barriers to further improvements in safety by ranking the importance of 10 potential threats. Causing the most concern is a ‘shortage of experienced personnel’ with an average score of 7.3. Respondents ranked ‘Fatigue/work practice’ (7.1) and ‘airline management experience/attitudes/culture’ (6.6) as the next most significant risks to improved aviation safety.
