I believe your figures are absolutely in the “ballpark”. Not easy to know obviously since the ionosperic hold off is issue to a lot of variability. At this instant I am happy that it is not a problem.
Because you informed us you’re within the spectrum I realize. But please make an effort to get Yet another viewpoint Every now and then.

• BTW, a single other impact on aircraft dynamics that has gone unmentioned is engine gyroscopic forces, considering the fact that they have the same way of rotation. This may act to translate pitch into yaw and VV but I have no idea by the amount of.

Victor Iannello says: January six, 2018 at nine:24 am @David: For the reasons you outlined and also other good reasons, I get the many simulations with a grain of salt. There are lots of unknowns about configurations and modeling inadequacies that the probability of using the simulations to correctly model what actually occurred is near zero. That’s why I took a Substantially various technique.
Here is some time sequence while in the simulation exactly where each engines flamed out simultaneously and there was no rudder trim.
Should you be correct about a near impact together the seventh arc till ~30S, no less than We are going to know this first through or immediately after the 2nd phase with the OI search, in the event the CSIRO places/hotspots have already been searched.
There is absolutely no logic in traveling in the direction of 40S100E (or YWKS or McMurdo or SP) following a flight that displays lots of signs of perfectly prepared, controlled and executed manouvres until ~eighteen:forty.
Comprehending what happened just after gasoline exhaustion is beneficial mainly because it helps us decide the space through the 7th arc to look. Even so, if we believe that the validity of the ultimate BFO values and also the connected descent charges (and at this stage, I'm not mindful of a explanation to doubt them), then the 0.
Nonetheless I've asked yet again irrespective of whether place specifics are held anyway, in the catalogue or in other places. A ship’s monitor with instances might help but Which may be unavailable and/or insufficiently thorough. Anything at all helpful that emerges I'll pass on even though I'm not extremely confident there will be anything.
ALSM states: January six, 2018 at two:53 pm Victor browse this site is correct. The evidence may be very potent for an stop point near the arc, but weak for just about any precise Clicking Here place along the arc. The first null search location and new drift analysis strongly indicates that the particular navigation manner wasn't a kind of 777 pilots believed was the probably manner, and therefore adopted by ATSB, IG and Other people. Once that constraint is taken off, we get a wide array of factors together the seventh arc as Victor has shown, possibly as significantly north east as S26 (or additional?
• Without any residual gasoline remaining the motor (currently being RR) would shut down when N3 dropped to 35%, getting triggered no upset. Have been there no relight the APU DC pump provide would go on from flame out to shut down. Under idle that could be break up in between the engine plus the APU for automobile-start off (on AC loss), the APU’s intake reducing the motor source down by about a hundred thirty lb/hr.
Should the significant descent charges were being induced by pilot-enter then There is certainly also the possibility of Restoration/pull-out by pilot-enter.
