ETOPS AREA OF OPERATION
Hi all,
Normally ETOPS AOO is defined by circles with a radius of the maximum diversion distance computed with approved N-1 speed and ETOPS approved time with zero wind ans zero ISA temperature deviation.
Sometimes, on dispatch, even staying inside the AOO we have higher N-1 flight time than approved (due to headwind for example) from ETP to nominated ETOPS enroute alternate. May we operate the flight in this case ?
Thanks for your reply !

I get this error :
ALERT TAG ETOPCVG
ALERT MSG THE ETOPS SEGMENT #1 IS NOT ETOPS COMPLIANT
FROM N0728.3 W13210.7 TO N0632.4 W13236.5
even the route is inside Area of Operation. Normally this error is triggered if the great circle diversion distance in still air is higher than the maximum diversion distance.
Here is the answer we get from Jeppesen :
I have investigated the issue with the false alert at ETOPS plans. Unfortunately I can reproduce the alert on several servers using different flight planning accounts. That means that your database entries are not the cause, but our JetPlan engine needs to be corrected. I have started the process by assigning ticket JPE-xxxx to the department concerned.
Sorry to say that I cannot advise any estimate for a solution.
