Non ETOPS Adequate airport 60 minutes
ETOPS segmentAn ETOPS segment is a portion of a route located further than - 60 minutes flying time at the- selected one-engine-out diversion speed, in still air- from an adequate airport. The ETOPS segment extends between the - ETOPS Entry Point (EEP) - ETOPS Exit Point (EXP). An ETOPS route may contain more than one ETOPS segment.

Adequate airport • Must satisfy the performance requirements applicable at the expected landing weight. • Following conditions are also considered at the expected time of use • 1. availability of the airport. • 2. availability of ATC services, communications, navaids, weather reporting, lighting equipment and emergency services (min fire cat 4 ). • 3. availability of at least one letdown aid (ILS, VOR/DME, VOR, NDB, ASR or PAR).
Suitable Airport • It is Adequate. • Weather forecasts + Notams indicate that, during the time period in which it might be used as alternate, weather conditions are above dispatch minima during period of validity.

Radius = time x speed
2. Speed =One-Engine-inoperative diversion speed See page 157
Mach/IAS speed schedule selected and declared by the operator and approved by the CAA • Speed range: extending between theMinimum Clean Speed and MMO/VMO, remaining engine thrust to be at Maximum Continuous Thrust (MCT) or less.
The selected one-engine-inoperative speed is used for the following purposes: • .establishing the area of operation • 2. establishing the diversion fuel requirements for the single engine diversion. • 3. establishing the net driftdown profile or level-off altitude to safely clear any en- route obstacle by the applicable margin.

SUITABLE EN-ROUTE ALTERNATE Airport To be suitable, an adequate airfield must have weather and field conditions ensuring a safe approach and landing during a required period of suitability.

Scenario 3 Only Engine Failure Optimum diversion FL (or MSA) at the approved speed strategy To be computed for each ETP !!

Equitime Point (ETP) • An ETP is a point on the route which is located at the same flying time from the two associated suitable airports. • 330 IAS on one engine at FL 100 after engine + pressurization failure (with actual average wind at FL 100).
4) Electronic computation This is done by the dispatcher using a dedicated PC program Dispatcher uses a Dispatch Checklist Exemple : see Page 125
Critical Point (CP) • The ETOPS Critical Point (CP) is the point, for which the difference between the - fuel expected to be on board (fuel to continue) - and the required ETOPS diversion fuel (fuel to divert) • is minimum or negative, thus requiring the carriage of additional ETOPS fuel reserves. • The Critical Point is usually, but not necessarily, the last ETP within the ETOPS segment or EXP.
