Very well said. This accident may be a result of the AB "just push the button" philosophie. The so called "crash proofed" aircrafts (Airbus) payed the tribute... |

Please, again, do not talk with such certitude when you don't know the system. |
OK, CONF, I'm happy to be proved wrong - enlighten me - when else will the Airbus FBW system limit a *pitch up* command from the sidestick *other than beyond alpha max* in *Normal Law*?
(Bear in mind I'm referring to some dusty old notes I made in my Software Engineering class back in 1997) |
Surely the THS MUST respond to SS elevator demand? There can be no other function for it. The problem is that no-one KNEW that it had. This is either a basic lack of knowledge of the a/c or a total blank-out of understanding in a crisis, and I do not know which.
Way back (after PGF) I suggested that surely there must be a THS angle, (AB, or Boeing - viz AMS) beyond which one should not normally stray, and that a mandatory 'Over-ride' function should be required before the THS is permitted to move past this limit, which has the effect of alerting the crew to what is happening and yet giving them the option of doing it if they feel it necessary. Strong nose-up THS forces have caused or threatened too many accidents. |

For a French crew (concerning fatigue), the primary reference time should still be Paris, even if they stayed few days in Brazil. I agree with you that it is highly improbable that Pilot's wife was in the cockpit rather than resting/sleeping in the cabin. Recovering cockpit seats seems a basic investigation work. The fact that the third seat was not supposed recovered doesn't tell anything about its state nor that the fourth was occupied. The fact that pilot's seats were recovered doesn't tell anything about their occupants bodies, certainly not that they were recovered seated and used for subsequent DNA tests, and so on... That's tabloid speculation. |
Additionally, "section 1.11.3" is mentioning that it is possible to mine further data from the on board computers that were retrieved, in regards to the sequence of speed calculations and rejection, around 2:10:xx as they have non-volatile storage that may still hold readable data. This is work and effort that is planned, so additional information will be available in a next report. I recall that the NTSB used this technique on the Cali AA B757 crash - they were able to read the processors from the CDUs, Control Display Units for the aircraft's FMC system to determine the last entries made, confirming why the turn was made towards the mountains during the descent. This may help in determining the answer to HN39s original question about the two second delay between the AFS disengagement, and the loss of airspeed presentations on the left PFD and the ISIS. |

BEA is mentionning that they will reconstruct ADR2 outputs from system logic. that FMGC 1&2, FCDC 1&2 and ISIS non volatile memories would be recovered and analysed in priority. It is still work in progress. |
again s 114.
in the time between 2:12 and 2:13 the pitch in the report is between 8deg and -8deg so if you try to fly pitch and power this time was not so bad looking, but it helps nothing he was not flying in this time, he was stalling pitch and power.... if I look at the acceleration longitudenale of this time periode and later than it is very interesting that there is all the time a acceleration longitudenal between -0,05 and -0,15, IMO this mean that you all the time has the feeling that the acceleration press you back in the seat as if the speed is ingreasing there are two possibilitis to have the feeling of such an acceleration longituenale, you can speed up to the front or you can sit with an backangle, the feeling is the same , this effekt is called one of the somaticgravic illusions (MIMPE and MICROBURST pointed out this earlier) and every flight simulator use this effekt for the simulation of longitudenal acceleratin.....[/FONT] UC Berkeley Vision Science || Bank's Lab 2 h 11 min 41PF:I have the impression (that we have) the speed 2 h 12 min 07 PF: I have the impression that we have a very high speed, so the feeling of the PF seems to be all the time he was speeding up.... and has to pull........... and I am wondering why the acceleration is so constantly with this great changes in pitch? is the pictured pitch with -8deg plausible at 2:12:00 and 2:12:50 ??? |
If, BOAC, PNF had arisen and opened the cockpit door for Captain duBois, that explains the possibility you broach re: #1 seat recovered sans Pilot.
It also would explain the seat's emptiness at discovery. Did PNF re-belt? We think Captain did not, so..... |

The airplane began to roll to the right and the PF made a left nose-up input. The stall warning sounded twice in a row. The recorded parameters show a sharp fall from about 275 kt to 60 kt in the speed displayed on the left primary flight display (PFD), then a few moments later in the speed displayed on the integrated standby instrument system (ISIS). 2 h 10 min 06 PF: J’ai les commandes I have control 2 h 10 min 09 PF: Ignition start Ignition start 02 h 10 min 10.4 : VS : « Stall, stall » (sans cricket) VS: "Stall, stall" (without cricket) 2 h 10 min 11 PNF: Qu’est ce que c’est que ça ?

The PF made nose-down control inputs and alternately left and right roll inputs. The vertical speed, which had reached 7,000 ft/min, dropped to 700 ft/min and the roll varied between 12 degrees right and 10 degrees left. The speed displayed on the left side increased sharply to 215 kt (Mach 0.68). The airplane was then at an altitude of about 37,500 ft and the recorded angle of attack was around 4 degrees. 2 h 10 min 17 PNF: On a perdu les les les vitesses alors… engine thrust A T H R engine lever thrust We've lost the the the speeds so ... engine thrust A T H R (off) engine lever thrust 2 h 10 min 18 PF: … de vitesse ... of speed 2 h 10 min 22 PNF: Alternate law protections Alternate law protections 2 h 10 min 24 PNF: Attends on est en train de perdre… Wait we're losing... 2 h 10 min 25 PNF: Wing anti-ice Wing anti-ice 2 h 10 min 27 to 2 h 10 min 31 PNF: Fais attention à ta vitesse Fais attention à ta vitesse Watch your speed Watch your speed PF: Okay, okay okay je redescends ok ok ok I'm going back down PNF: Tu stabilises stabilize (“stay there”) PF: Ouais Yeah PNF: Tu redescends You're going back down 2 h 10 min 33 PNF: Selon les trois tu montes donc tu redescends According to the three you're going up, so you go back down (meaning the three vertical speed indicators... ) 2 h 10 min 35 PF: D’accord Agreed 2 h 10 min 36 PNF: T’es à ...

The thrust levers were positioned in the TO/GA detent and the PF maintained nose-up inputs. The recorded angle of attack, of around 6 degrees at the triggering of the stall warning, continued to increase. The trimmable horizontal stabilizer (THS) passed from 3 to 13 degrees nose-up in about 1 minute and remained in the latter position until the end of the flight. Around fifteen seconds later, the speed displayed on the ISIS increased sharply towards 185 kt;it was then consistent with the other recorded speed. The PF continued to make nose-up inputs. The airplane’s altitude reached its maximum of about 38,000 ft, its pitch attitude and angle of attack being 16 degrees. 2 h 10 min 56 PF: (TOGA) (TOGA) 2 h 11 PNF: Surtout essaie de toucher le moins possible les commandes en en latéral hein Above all, try to touch the controls as little as possible in in lateral, hey ?!

During the following seconds, all of the recorded speeds became invalid and the stall warning stopped. The altitude was then about 35,000 ft, the angle of attack exceeded 40 degrees and the vertical speed was about -10,000 ft/min. The airplane’s pitch attitude did not exceed 15 degrees and the engines’ N1’s were close to 100%. The airplane was subject to roll oscillations that sometimes reached 40 degrees. The PF made an input on the sidestick to the left and nose-up stops, which lasted about 30 seconds. 2 h 11 min 41 PF: J’ai l’impression (qu’on a de) la vitesse I have the impression (that we have) some speed 2 h 11 min 43 [Bruit d’ouverture de la porte du cockpit] [Sound of the cockpit door opening] CAP: Eh qu’est-ce que vous (faites) ?

At that moment, the thrust levers were in the IDLE detent and the engines’ N1’s were at 55%. Around fifteen seconds later, the PF made pitch-down inputs. In the following moments, the angle of attack decreased, the speeds became valid again and the stall warning sounded again. 2 h 12 min 04 to 2 h 12 min 07 PF: J’ai l’impression qu’on a une vitesse de fou non qu’est-ce que vous en pensez ?

It also would explain the seat's emptiness at discovery. Did PNF re-belt?

CVR: 2 h 11 min 43: Bruit d’ouverture de la porte du cockpit No pilot is reported to have opened the cockpit door - sound of door's opening is recorded: captain is back while pilots are doing their task. Nor anywhere is it reported that the captain was ever seated. |
Hi takata. good morning.
I have been reading at least six people whose posts I admire greatly. They are not convinced of the seating, so I am definitely not persuaded! Look, the last thing I do in crash drill is unbelt, a sign to me that we are arrivee. A buckled belt is proof of belt connection, a lack thereof could be anything. If I am going to drown, (I care not what the instruments say, I can swim!), the belts come off, so the cockpit is not well known. The conversation is. At 2;11:40, the PF input NOSE UP, and Left ROLL to the stops. Sound familiar? A similar input at A/P loss is recorded, n'est-ce pas? So PF has input these two recorded parameters. He is constantly yammering about his controls, and comments several times to indicate his PITCH command is wack. There was something "wrong" with this Aircraft........... takata: I admit, regretfully, that I oversold the VS damage. If it has soured anyone on even casually addressing airframe damage, I am profoundly sorry....... |
takata, I agree with your summary.
But the summary presumes that the captain is able to re-enter the cockpit by himself. If he cannot, would you not think that the BEA would note that the PNF had to leave his seat to open the door for him at a most critical time in the flight? |
SATURNV
Mega respects, kind Sir. The BEA have presumed nothing. Neither has their report. I will offer, having been involved in these teams, (NOT BEA), that parsed and spooned rhetoric can be completely innocent, and taken in very dark ways. In damage control, we say "FIRST RULE, do not CREATE MORE". |
Hi SaturnV

@Bearfoil, There is absolutely no discussion about who was seated where: neither who was doing what; facts: PF (PIC) was seated in the right hand seat; PNF was seated in the left hand seat. Who discussed those facts in your fertile imagination? We had previous discussion about whilch of the two pilots was PF or PNF, until the report. Now it is closed. |
SaturnV wrote "But the summary presumes that the captain is able to re-enter the cockpit by himself. If he cannot, would you not think that the BEA would note that the PNF had to leave his seat to open the door for him at a most critical time in the flight? "
With the importance of the words and actions of PF & PNF it seems inconceivable that the BEA would not note PNF arising from his seat and allowing the Captain to enter the flight deck. Any such action would impact upon the focus PNF would have (I assume it would be he) on the developing situation. Unless there was a third party on the flight deck able to do open the door or the Captain had a way to enter that did not require the intervention of PF/PNF? Someone occupying seat four on the flightdeck? The BEA should have addressed this issue in the report - stating just who was on the flight deck - for the avoidance of doubt and speculation. Their raising of seat four from the crash site has indicated some issue that needed to be investigated. It would not be out of place for them to address this matter now. |
There are other definitions for seat that you may be missing. Other than geographical.
|
takata, if they left the cockpit door unlocked while the captain took his rest, I believe that would be a security violation.
I assume Air France policy and procedures require the cockpit door to be locked, and that once locked, the door can only be unlocked from the inside. If that is true, and only the PF and PNF are in the cockpit, then the PNF would need to leave his seat to unlock the door and let the captain return, and the PNF would then again take his seat, fasten his belt, and see what had happened in the __ seconds it took him to let the captain in. |
takata,
Have you trained UAS in the sim? The one where conditions are unbelievably bad, and three separate pilots are trying to fly the a/c? And if you fail, a bullet to the brain? Each seat has its own "gestalt". Authority can occupy any, but only one at a time. NEVER, EVER, TWO. It is not a goddam democracy. |
