In compliance with Section 8.8.2 (4) of the FCOM “Check of engagement and
disengagement of the Go-around mode” the crew could arm the Go-Around mode by pressing
the APPROACH and GLIDE SLOPE buttons on autopilot control panel. It should be noted that
these actions are only prescribed to be performed on the ground during the preflight inspection
of the autopilot and cannot be performed in flight according to the FCOM. Without meeting this
condition automatic go-around was impossible. However, the APPROACH and GLIDE SLOPE
buttons as well as the GO-AROUND button were not used by the crew in the accident flight. The
flight recorders did not record relative callouts or data.
Note: On April 6, 201045 during an ILS approach at Warsaw airport this
aircraft made an automatic go-around. The FDR recorded the
relative on/off-signals (autoflight modes): Approach, Glide slope,
and Go-around (Figure 44).
What they mean then? That GO-AROUND button
was not recorded or
couldn't be recorded?
