The aircraft is in a large black hole with no radar monitoring, relying totally on the pilots not making an error and the EGPWS system working.
I hope the public are not reading this fearful crisis.
My red for emphasis.
Why did the pilots throw out their approach plates and turn off their (multiple) coupled GPS.
What shall we do in the large area without radar coverage?
Are you going to provide the link to the FSI paper?
