777-300ER ETOPS Planning

[FlyGuy42 4]

Hello everyone,

 

I'm planning my first ETOPS flight with the -300ER, and I have noticed something unusual. The performance profile on PFPX shows a lower diversion speed for the ETOPS scenario to the -200LR, resulting in a reduced diversion distance.

 

Now this came as a bit of a surprise to me as the two aircraft use nearly identical engines, albeit with different thrust ratings. However, I guess this would make sense, as we are dealing with a higher gross weight and drag. The manuals didn't help much, as they directed me to look at airline specific procedures.

 

Is this difference in diversion speed schedules also the case with IRL dispatching? The scenario I'm after is ONE ENG DECOMP and I'd appreciate if someone could offer some real life insight into ETOPS planning with this aircraft.

 

Best regards.

Suprojit,

 

I don't know if these will help but there from the Aerosoft Forum in relation to PFPX. I hope the posts below are useful and able to help you ?

Thanks Jason, I had a look through them, but they didn't seem to answer my question. There didn't seem to be any information on the speed schedule for diversion for the -300ER.

 

Regards.
