ETDO - An example

[extricate]

Hi there,

Got hold of a flightplan and want to know more about ETDO scenarios. I've attached a part of the flightplan.

Can I know what does the the EET beside Entry 1E, 2D, 1D means? For example, for 1E (1 engine driftdown), the EET is 1:55 (1hr 55mins into the flight), but what's the significance of it? So what if i encounter an engine failure 5mins before/after 1:55? If before, i divert to WMKP, if after I divert to VCBI?

Thanks
