Some Etops Help
Hello..
ETOPS;
Rule time 90-120-180
Engine Out Speed just one for Example: 450Kts
With this data you can create Etops Aera Operation Wind=0
Easy...
Last Airport that cover 60Minutes = 450NM you are None ETOPS Area
Then you have a route where the airport range 450NM doesn´t cover the route. You need to extend that area for 90Minutes/675NM or 120Minutes/900NM.
Then you have a suitable aiport for ETOPS within that distance range, remember 675NM or 900NM Wind=0.
ETP Will be the equal time point between the ETOPS Airports.
When you run a Flight plan check the distance from ETP to Airport 1 and ETP Distance to Airport2 that will the same (Equial time/Distance Point), Because the real plan has wind if wind=0 then Time=Distance.
Also that distance will be within the range calculated in the ETOPS Area Operation.
For 90Minutes < 675NM
For 120Minutes < 900NM
I Hope this help your question.
Confirm if you agree and understand?
All the Best.
