ETOPS TIME, DISTANCE Interpretation
All,
I like to support Axel's explanation. The ETP in this example is 02:12 (normal people will say
more than 120 minutes) but this ETP are under 120Minutes due the distance are within 900NM.
Here some wrong interpretations;
ETP TIME are 2.12= 132 Minutes (Pilots beleve are over 120Min)
But the pilots need to check the distance.
If this distance are inside the 900NM Rule Distance for ETOPS 120Min
That was calculated with WIND=0 for a particular Speed is this case 450Kts
THIS ETP 2.12 is 120Minutes ETOPS operation.
