The box that has been found was the flight-data recorder, which collects information on altitude, heading, speed, horizontal and vertical acceleration and engine function.
22.
It is only during the radial ( constant increase in pitch ) or vertical acceleration that the lift vector is larger than the weight vector.
23.
The frequency content of the suspension movement rate is similar to the frequency content of chassis vertical acceleration and also tire / road vertical loading.
24.
The FDR did not record all of the parameters that it was supposed to record, mainly vertical acceleration readings were missing and heading indications were abnormal.
25.
When traditional deep V-hulled boats travel at high speed in rough conditions, they jump from wave to wave and land with high vertical acceleration or g-force.
26.
Thrust faults, where one side moves over the other as if on a ramp, could pose greater threats because their quakes tend to have higher vertical acceleration.
27.
The flight recorder records variables during the aircraft's flight like airspeed, altitude, heading and vertical acceleration that often give investigators clues to the cause of the crash.
28.
During this time the jet's airspeed decreased from 270 to 215 knots and as the peak altitude was approached, the vertical accelerations changed rapidly from 1G to about-2G.
29.
Two types of otolith organs are housed in the vestibule : the saccule, which points vertically and detects vertical acceleration, and the utricle, which points horizontally and detects horizontal acceleration.
30.
Crew judgement is most reliable to determine hard landing, as determination based on recorded acceleration value is difficult and not advisable, partially because there is no recording of true vertical acceleration.
