BIRIMBAO,
EOISIDs are Lateral and Vertical Navigation procedures designed to ensure Obstacle Clearance following failure of 1 engine at the most critical point during Takeoff until the aircraft has achieved a safe altitude (usually MSA)
EOISIDs are -
(1) Created by the operator, who will use the services of their own Performance Engineering staff (or a sub contractor),
(2)
NOT known to ATC, unless the operator is a "good" operator and advised ATC of the company's OEISIDs,
(3)
NOT all encompassing for all aircraft types, they are type specific,
(4) Usually contained within 25 nm for the purposes of utilising MSA, but not necessarily so.
To repeat that which has been said hundreds of times on other forums, following the "Normal" PANS-OPS or TERPS SID
DOES NOT guarantee obstacle clearance following engine failure. Normal SIDs are designed for All Engines operation, and would typically only be achievable following engine failure for an aircraft at very low weights.
OzExpat, is there a good reason why EOISIDs for 2, 3, and 4 engined aircraft can't be designed as "Government Issue" by the Regulatory Authority for each runway? I always wanted to ask that, and it would standardise things very much, and add immeasurably to safety for those "lousy" operators who don't give a damn about such things. (It would also save a lot of work for people like me who have to design them
)
