I mean, if "GO-AROUND" btn was deactivated because of deactivated ILS, will it sent "pressed" signal or it is physically switched off by some relay?
This is something i am interested about too.
The report prooves that the
activation of the GO-Around is recorded on the FDR on a ILS guided approach,
not the push of the button! But in our case the GO-Around mode was
not armed in the first place and
couldnt be activated by the push of the button.
So most probably, even if the crew pushed the button, this wouldnt have been recorded on the FDR.
I am starting to consider, that they might have actually pushed the button at 1st 100m callout (the polish report states that a GA callout is heard on the CVR at that time).
The
strongest argument for that is the fact, that using the
automatic GA was the procedure setup by the crew minutes before.
After pressing the button, as no decreasing altitude callouts were made for next 6-7 seconds, they thought everything was going well and the GA was about to happen, so why not take advantage by looking out the window checking out the fine scenery, instead of checking boring instruments.
When the Navigator called out 100m for the second time, the FO called: "Normal".
Now that is strange call open to speculations. Maybee by that he meant:
"Yeah, we had a steep descend so there was some loss of height due to intertia after activating GA. Now we are at 100m again which means we are ascending. So everything is fine fine fine."
Then the Navigator calls out 90m, the FO is like:
"Wait a minute, i thought we were ascending".
In a matter of only 0.9 seconds the FO called "We are leaving". Which is different from the "Go Around!" he called before:
Notice the
"We", aka manual GA.
