Amazon Prime Air becomes first operator to secure SAIL 4 approval from UK Civil Aviation Authority

Amazon Prime Air has become the first operator in the world to obtain a SAIL 4 Operating Authorisation and Flightworthiness Validation from the UK Civil Aviation Authority. The approval expands Prime Air's eligible delivery area around Darlington from around 600 customers to roughly 8,000, who can receive items weighing up to 5 lbs (2.2kg) in under two hours. The CAA assessed Prime Air's operation, aircraft, organisation and risk approach, and the MK30 drone uses machine-learning detect-and-avoid systems plus a redundant monitoring computer, six motors and a three-cell battery.
