The flight route which was taken after the plane experienced flown over and above radar selection can now be reconstructed with a A great deal increased diploma of self confidence. The most up-to-date findings are that For starters, the pilot reduced pace from M0.eighty four to M0.81 Soon prior to traveling outside of radar selection. Secondly, that he remained on flight route N571 at FL350 until eventually he was 25NM out from waypoint IGOGU, at which place he commanded the FMC to fly toward a pre-established manually inserted waypoint, recognized as S41.00, E88.00. Thirdly, that when the aircraft commenced the change south, the pilot started to cut back speed from M0.
There isn't a procedural requirement for this kind of manoeuvre. The founded contingency processes enable aircraft to turn remaining or straight away from an airway, matter towards the relative posture of other aircraft, adjacent airways and terrain. There is not any necessity to cross the airway the plane has left, at ninety degrees or some other angle.
To me this bears the signs of a pilot-induced high speed steep descent…Didn't see conclusive arguments however that refute this chance.
Depending on this restricted content you and others have shaped the ‘impression’ that the damage and seperation sample with the parts was because of superior pace effects and/or aero dynamic forces. And you have some powerful arguments I see.
If my arguments make no sence within your viewpoint you should reply with contra-arguments depending on what I mentioned.
Victor Iannello states: January 6, 2018 at 9:24 am @David: additional info For the reasons you mentioned and also other motives, I acquire every one of the simulations with a grain of salt. There are plenty of unknowns about configurations and modeling inadequacies that the probability of using the simulations to properly design what essentially transpired is near zero. That’s why I took a Considerably distinctive tactic.
As an additional aside, I nevertheless have flags to turn the spheroidal factors from the design off (again into a spherical earth, which happens to be how we all labored early on, together with Inmarsat) as well as influence on the BTO calculation is huge. Summary: everyone is using a spheroidal Earth product.
In case you experienced bothered to open up any of your Excel spreadsheets, you will see This is actually the First bearing.
Robotic-centered link automation solutions enable the flexibility to correctly manage both seasonal and sustained progress.
The BFO error consists of two elements – 1 could be the improperly calculated Doppler payment (most when the satellite is furthest previously mentioned or under the equator), and one other is the Doppler from the satellite motion alone (greatest with the satellite is at the equator).
I had no problem and take pleasure in the great shape of your SLOP transform in your paper. Nonetheless I assumed it had been controversial to mention the SLOP convert and SDU reboot implies the pilot was addressing a mechanical concern, and never intentional diversion of some kind.
I do think at this incredibly minute almost nothing at all will impact OI’s lookup space. OI has possible architected a look for strategy, and will stick to it. That is a Significantly diverse Idea than an announcement relating to refinement with the lookup location.
three) Investigation by Singapore and Indonesian officials pointed to mechanical malfunction. Meanwhile, the US NTSB ruled that the occasions and facts instructed a deliberate action to the Component of the pilot.
You'll be able to tell which connection belongs to which track by investigating The three digits before the .xlsx in each case:
