Question

(a) Analyse the computed data from Q5 and use Matlab to plot the following graphs of data obtained from the longitudinal (roll) axis direction of the aircraft:

(i) Horizontal Acceleration vs Time

(ii) Ground Speed vs Time

(iii) Horizontal Distance Run vs Time

over the entire duration of the take-off run, assuming that there is no head or tailwind at take-off.

(b) Assuming that the accelerometers mounted onboard the B787 sample and update at an interval of 1 second and use the trapezoidal rule to compute all numerical integrations of horizontal distance, appraise the result of part versus approximations using the trapezoidal rule for the horizontal distance covered at the end of the take-off run. Show your Matlab code for both computations.
