Victor Iannello claims: January 6, 2018 at 10:fifty eight am @ASLM: I am not referring for the simulators’ modeling of flight dynamics for out-of-envelope ailments. Somewhat, I'm referring towards the shortcomings on the design in a devices degree and unknowns regarding the configuration of the aircraft. I feel the BFO values reveal that either lateral asymmetry or nose-down input brought about the aircraft to enter an ever more steep descent.
• BTW, one particular other impact on plane dynamics which has long gone unmentioned is engine gyroscopic forces, due to the fact they've exactly the same direction of rotation. This could act to translate pitch into yaw and VV but I have no idea by just how much.
Nevertheless I have requested once more irrespective of whether position information are held in any case, during the catalogue or elsewhere. A ship’s keep track of with instances may possibly help but Which might be unavailable and/or insufficiently in-depth. Anything handy that emerges I will pass on nevertheless I am not pretty confident there will be anything.
Here's time sequence during the simulation where both of those engines flamed out at the same time and there was no rudder trim.
Feasible, Certainly; nonetheless, it’s also achievable they modeled a little amount of residual gasoline, ample to allow a short relight, but not necessarily agent of that found in the real plane. I might urge warning in accepting the relight seen from the simulator displays precisely what would happen in serious lifetime.
I regard your perform very but I do think I observed a primary flaw that influences your outcomes to conclude over a latitude just far too significantly north imo.
But whether or not ClearMetal succeeds in the market or not, it is evident that intriguing, new predictive analytic solutions will significantly be readily available in logistics.
I don’t Assume any person doubts it is feasible to Get better from a steep descent by a skilled pilot. It does involve watchful Procedure in the controls making sure that wing and tail elements are certainly not ruined by superior aerodynamic hundreds.
Because you told us you’re on the spectrum I have an understanding of. But you should attempt to get A further standpoint Every so often.
In about ten times she is going to commence on the lookout for the airliner, which disappeared after mysteriously reversing training course early into its overnight flight from Kuala Lumpur to Beijing.
I guess if the whole reasoning powering the ultimate BFOs is incorrect (which I don’t Consider it's – since it is two unbiased info factors and no strong reason to state the particles doesn’t match), then You need to have an extremely very clear trajectory, such as BTOs and BFOs, to help make any search economically viable.
1839.fifty Slow-right down to close to M0.72 was comprehensive. Shortly, the pilot initiated a gradual speed-up from M0.seventy two to M0.eighty two and at the same time, started to climb from FL350 to FL390. This put together speed-up and climb took an estimated 17 minutes, and was done at about 1857. The pilot experienced apparently made the decision in advance on frequent Mach cruise as one of the most appropriate cruise possibility, and it’s thus affordable to believe that the gradual-down, speed-up manoeuver was a variety-testing training performed along side the FMC, the objective of which was to detect the Mach pace/altitude mixture that generated the best range from the remaining gas. The FMC was navigating towards a guide waypoint Situated some 200Nm past the plane’s gas vary, Therefore by far the most easy way to locate the optimum speed and altitude was to gradually maximize each speed and altitude and keep track of the various FMC variety-to-go readout.
This all going on a single moment Look At This after second motor flame-out doesn't fit the ATSB simulations imo. And it doesn't in good my response shape the corrections towards the hydraulics into the left wing flaperon and maybe other corrections (rudder trim?).
The Australian investigators attained One more 777 flaperon from Boeing and set it adrift to determine the speed and way it moved in ocean currents.
