Our aerospace engineers assist with flight testing and provide
technical analysis in the areas of flight path reconstruction and
AvSafe's Engineering Department utilizes radar data and recorded
flight data to reconstruct accident flight paths and analyze
aircraft performance. These images, plots, and animations can assist
investigators in determining factors that are causal to the

A three dimensional
flight path reconstructed from onboard aircraft data.
The flight path depicts the time, altitude, and position of
the aircraft throughout the flight. The
flight path was overlaid on satellite imagery/aerial photography in
order to depict actual terrain features below the aircraft.
Weather radar imagery
and onboard aircraft data were synchronized to provide information
on the aircraft?s location with respect to thunderstorms and rain.
from the onboard accelerometer prior to an inflight breakup were
recorded to non-volatile memory. AvSafe, LLC performed an analysis
of the recorded acceleration data to determine the actual
acceleration/G load of the aircraft.
Aircraft pitch, roll,
and pressure altitude as recorded in onboard aircraft data.
recorded in onboard aircraft data. The data shows a loss of
indicated airspeed on both the pilot and copilot Primary Flight
Displays (PFD) as a result of inflight pitot tube icing.
AvSafe, LLC was able
to reconstruct the actual indicated airspeed of the aircraft using
other parameters recorded in the onboard aircraft data.
Reconstruction of indicated airspeed allowed experts to compare
airspeeds flown by the accident aircraft to airspeed limitations
from the Airplane Flight Manual (AFM).
