Visualizing ET302 data

The following graph combines altitude data (feet AMSL), ground speed data (knots), and vertical speed (feet per minute) from ET302.

Important note: altitude data reported by ADS-B is the pressure altitude at standard pressure and not the altitude above ground level. This is why some values may be below the ground altitude at Addis Ababa airport. Standard pressure is 1013 hPa, pressure reported at HAAB | ADD at the time of accident was 1029 hPa. Airport elevation is 7625 feet MSL. All altitude data when the aircraft is ‘on ground’ is reported as 0. Airborne altitude values are report as stated above.

In the graph below we’ve removed altitude values of 0 for visual clarity.

For additional clarity, the third graph below shows only the ground speed.
