EOSID

The document discusses research on establishing criteria for ensuring safe single-engine operation during departure (EOSID) using RNP 1 navigation. It presents the criteria developed, including protection areas that account for factors like wind, and validates the approach through simulator and flight tests. The conclusions are that the new RNP 1 EOSID criteria and wind model allow safe single-engine operations and are effective based on validation.
