Applying the precautionary Principle, I make a new analysis of Air France Flight AF 447 assuming that the sum of the world’s dam content changes at any time applies a force on the plane every time an earthquake is caused by the dams, from the moment it takes off to the time of its landing. This vertical force, which is down during the dry season, October to May, is orders of magnitude fold the total engine thrust developed by the engines.  The stand alone acceleration of the plane caused by this application of force assumed to act on the centre of gravity of the plane is computed. This acceleration in g’s is a measure of the severity of the damage to the plane. By juxtaposing the final report’s narrative on the history of the flight’s factual information(1) with the acceleration suffered by the plane at various times as measured by analysing the data on earthquake(s) near that time, evidence is produced of proof of the consequences to the plane caused  by the dam content changes which also intensify the weather during each hydrological cycle(2). The exercise follows.  This should be read with the Final Report of BEA( Ref 1). The Buffet Warning is so so real with dams complicit, not only for AF 447 but for EgyptAir MS804 as well as MH 370’s complete disappearance, that this study must be duly addressed and confirmed by all concerned and aware of the unacceptable dangers of the risk. The risk must be evaluated and considerably reduced as the final report so tragically reveals (1). There is nothing more tragic than ignorance in action.






 

For our purposes the map above is just the thing we want in order to explain the phenomenon of the catastrophic plunge of the Air France Airbus:

1 - FACTUAL INFORMATION 1.1 History of Flight.

On Sunday 31 May 2009, the Airbus A330-203 registered F-GZCP operated by Air France was programmed to perform scheduled flight AF 447 between Rio de Janeiro Galeão and Paris Charles de Gaulle. Twelve crew members (3 flight crew, 9 cabin crew) and 216 passengers were on board. The departure was planned for 22 h 00. At around 22 h 10, the crew was cleared to start up engines and leave the stand.




Legend: time refers to the time of the dam caused earthquake, damquake. SM is the seismic moment of the quake. The figure multiplied by 10^19.05 gives the value in Newton meters. CG refers to the centre of gravity of the water masses behind the world’s dams for the period mentioned above the location of the centre of gravity. Dist,km refers to the distance between the location of the epicentre of the quake and the centre of gravity of the dams, as defined above. DBCM denotes the dam content change in BCM which caused the quake. Force is the force in newtons(N) applied on the aircraft at its centre of gravity. Mass in kg is the mass of the fully loaded aircraft AF 447 during the flight.

The aeroplane left the stand with a calculated weight of 233,257 kg. The estimated takeoff weight was 232,757 kg for a maximum authorised takeoff weight of 233 t.



Takeoff took place at 22 h 29. The Captain was Pilot Not Flying (PNF); one of the copilots was Pilot Flying (PF). At the start of the Cockpit Voice Recorder (CVR) recording, shortly after midnight, the aeroplane was in cruise at flight level 350. Autopilot 2 and auto-thrust were engaged. Auto fuel transfer in the “trim tank” was carried out during the climb. The flight was calm.

Note: At about 0 h 30 the crew had received information from the Operations Control Centre( OCC) about the presence of a convective zone linked to the inter-tropical convergence zone (ITCZ) between SALPU and TASIL. Ominous indeed. But why did not the pilots turn back? See Ref 1 for the tragedy of ignorance in action.



 


Note the enormous application of vertically downward force by dams on the plane at 00:53:31.720Z on 2009-06-01: 332 times the engine thrust of the two engines together. The total thrust developed is a maximum of 622000 Newtons.


At 1 h 35, the aeroplane arrived at INTOL point and the crew left the Recife frequency to change to HF communication with the Atlántico Oceanic control centre. A SELCAL Selective Calling System test was successfully carried out, but attempts to establish an ADS-C Automatic Dependant Surveillance-Contract ( ADS-C) connection with DAKAR Oceanic failed.
  






Shortly afterwards, the co-pilot modified the scale on his Navigation Display (ND) from 320 NM to 160 NM and noted “…a thing straight ahead”. The Captain confirmed and the crew again discussed the fact that the high temperature meant that they could not climb to flight level 370.
 



At 1 h 45, the aeroplane entered a slightly turbulent zone, just before SALPU point.

The crew dimmed the lighting in the cockpit and switched on the lights “to see”. The co-pilot noted that they were “entering the cloud layer” and that it would have been good to be able to climb. A few minutes later, the turbulence increased slightly in strength. Shortly after 1 h 52, the turbulence stopped.
 





The co-pilot again drew the Captain’s attention to the REC MAX value, which had then reached flight level (FL) 375. A short time later, the Captain woke the second co-pilot and said “[…] he’s going to take my place”. At around 2 h 00, after leaving his seat, the Captain attended the briefing between the two co-pilots, during which the PF (seated on the right) said specifically that “well the little bit of turbulence that you just saw we should find the same ahead we’re in the cloud layer unfortunately we can’t climb much for the moment because the temperature is falling more slowly than forecast” and that “the logon with DAKAR failed”.
Note that at this point,  the force applied on the plane by the dams at 01:56:48Z would be 22 times the total engine thrust of 622000 N  and equal to 6g. At 1:43:02.450Z, the applied force would have been 71 times the total thrust of the engines - an acceleration of 19g.

  



Then the Captain left the cockpit. The aeroplane approached the ORARO point. It was flying at flight level 350 and at Mach 0.82. The pitch attitude was about 2.5 degrees. The weight and balance of the aeroplane were around 205 tonnes and 29%.

The two copilots again discussed the temperature and the REC MAX. The turbulence increased slightly. At 2 h 06, the PF called the cabin crew, telling them that “in two minutes we ought to be in an area where it will start moving about a bit more than now you’ll have to watch out there” and he added “I’ll call you when we’re out of it”. At around 2 h 08, the PNF proposed “go to the left a bit […]”. The HDG mode was activated and the selected heading decreased by about 12 degrees in relation to the route. The PNF changed the gain adjustment on his weather radar to maximum, after noticing that it was in calibrated mode. The crew decided to reduce the speed to about Mach 0.8 and engine de-icing was turned on. At 2 h 10 min 05, the autopilot then the auto-thrust disconnected and the PF said “I have the controls”. The aeroplane began to roll to the right and the PF made a nose-up and left input. The stall warning triggered briefly twice in a row. The recorded parameters showed 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). The flight control law reconfigured from normal to alternate. The Flight Directors (FD) were not disconnected by the crew, but the crossbars disappeared.

Note: Only the speeds displayed on the left side and on the ISIS are recorded on the FDR; the speed displayed on the right side is not recorded. At 2 h 10 min 16, the PNF said “we’ve lost the speeds ” then “alternate law protections”. The PF made rapid and high amplitude roll control inputs, more or less from stop to stop. He also made a nose-up input that increased the aeroplane’s pitch attitude up to 11° in ten seconds. Between 2 h 10 min 18 and 2 h 10 min 25, the PNF read out the ECAM messages in a disorganized manner. He mentioned the loss of autothrust and the reconfiguration to alternate law. The thrust lock function was de-activated. The PNF called out and turned on the wing anti-icing. The PNF said that the aeroplane was climbing and asked the PF several times to descend. The latter then made several nose-down inputs that resulted in a reduction in the pitch attitude and the vertical speed. The aeroplane was then at about 37,000 ft and continued to climb. At about 2 h 10 min 36, the speed displayed on the left side became valid again and was then 223 kt; the ISIS speed was still erroneous. The aeroplane had lost about 50 kt since the autopilot disconnection and the beginning of the climb. The speed displayed on the left side was incorrect for 29 seconds. At 2 h 10 min 47, the thrust controls were pulled back slightly to 2/3 of the IDLE/ CLB notch (85% of N1). Two seconds later, the pitch attitude came back to a little above 6°, the roll was controlled and the angle of attack was slightly less than 5°. From 2 h 10 min 50, the PNF called the Captain several times. At 2 h 10 min 51, the stall warning triggered again, in a continuous manner. The thrust levers were positioned in the TO/GA detent and the PF made 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) began a

nose-up movement and moved from 3 to 13 degrees pitch-up in about 1 minute and remained in the latter position until the end of the flight. Around fifteen seconds later, the ADR Air Data Reference , ADR3 being selected on the right side PFD(PFD Primary Flight Display ), the speed on the PF side became valid again at the same time as that displayed on the ISIS. It was then at 185kt and the three displayed airspeeds were consistent. The PF continued to make nose-up inputs. The aeroplane’s altitude reached its maximum of about 38,000 ft; its pitch attitude and angle of attack were 16 degrees. At 2 h 11 min 37, the PNF said “controls to the left”, took over priority without any callout and continued to handle the aeroplane. The PF almost immediately took back priority without any callout and continued piloting. At around 2 h 11 min 42, the Captain re-entered the cockpit. During the following seconds, all of the recorded speeds became invalid and the stall warning stopped, after having sounded continuously for 54 seconds. 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 aeroplane’s pitch attitude did not exceed 15 degrees and the engines’ N1’s were close to 100%. The aeroplane was subject to roll oscillations to the right that sometimes reached 40 degrees. The PF made an input on the side-stick to the left stop and nose-up, which lasted about 30 seconds. At 2 h 12 min 02, the PF said, “I have no more displays”, and the PNF “we have no valid indications”. 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 triggered again.

At 2 h 13 min 32, the PF said, “[we’re going to arrive] at level one hundred”. About fifteen seconds later, simultaneous inputs by both pilots on the side-sticks were recorded and the PF said, “go ahead you have the controls”. The angle of attack, when it was valid, always remained above 35 degrees. From 2 h 14 min 17, the Ground Proximity Warning System (GPWS) “sink rate” and then “pull up” warnings sounded. The recordings stopped at 2 h 14 min 28. The last recorded values were a vertical speed of -10,912 ft/min, a ground speed of 107 kt, pitch attitude of 16.2 degrees nose-up, roll angle of 5.3 degrees left and a magnetic heading of 270 degrees. No emergency message was transmitted by the crew. The wreckage was found at a depth of 3,900 metres on 2 April 2011 at about 6.5 NM on the radial 019 from the last position transmitted by the aeroplane.

3. Aerodynamics-Wikipedia:

An aircraft in flight is free to rotate in three dimensions: pitch, nose up or down about an axis running from wing to wing; yaw, nose left or right about an axis running up and down; and roll, rotation about an axis running from nose to tail. The axes are alternatively designated as lateral, vertical, and longitudinal. These axes move with the vehicle and rotate relative to the Earth along with the craft. These definitions were analogously applied to spacecraft when the first manned spacecraft were designed in the late 1950s.
These rotations are produced by torques (or moments) about the principal axes. On an aircraft, these are intentionally produced by means of moving control surfaces, which vary the distribution of the net aerodynamic force about the vehicle's center of mass. Elevators (moving flaps on the horizontal tail) produce pitch, a rudder on the vertical tail produces yaw, and ailerons (flaps on the wings that move in opposing directions) produce roll. On a spacecraft, the moments are usually produced by a reaction control system consisting of small rocket thrusters used to apply asymmetrical thrust on the vehicle.
