5 steps to convince about safety

Why air safety improvement is too slow (organisation)?

Why air safety improvement is too slow (culture)?

Why training is the main solution to human factors issues

Human factors still the current challenge of the industry

No limits for the understanding of human factors

Suggestions for a discipline committee

Too long briefings

Current CRM have reach its limits
