Standards for passenger evacuation from aircraft not upated finds USA audit.

The current standard is to demonstrate that the aircraft can be evacuated by all passengers in 90 seconds using half the exits. There have been increasing number of evacuations where it has been observed that the pasengers were carrying their personal belogings or delaying the evacuation to collect their belongings.The test scenario is conducted with motivated volunteers who have been briefed on the scenario. However a real evacuation with changing passenger profile will present different challenges.FAA largely updates its evacuation standards only after accidents, and its last update that was based on an accident occurred in 1991. FAA also has not conducted sufficient research on passenger behaviors and seat dimensions to determine how they affect evacuation standards. Furthermore, FAA does not collect comprehensive data from evacuations or data from aircraft model certifications to identify emerging risks and needs for regulation updates.Read the full report here FAA’s Process for U…

No Human Factor experts, Investigations flawed, Policy maker cluseless about Safety management. This is the Nadir.

Aviation safety in India is truly at the Nadir with the unfortunate accident of the Air India Express B737 at Calicut on 7th Aug 2020. After 22nd May 2010 when the Air India Express B737 crashed at Mangalore, there was a thorough investigation with numerous recommendations. Unfortunately, a year down the line all was forgotten.
 
2019 monsoon saw a spate of runway excursions. Instead of determining the root cause, the regulator decided to address the symptom. They cracked the whip and suspended more than 40 pilots. A proud regulator made a statement that cracking the whip worked and there were no SOP violations in December 2019. 

Problem:
1. The policy makers have no understanding of risk analysis and safety management systems.
2. Investigations are flawed and no action is taken on the real culprits.
3. There are no human factor experts to understand why the error passes through all the barriers to end up in an accident.
