Emerates B777 DBX
I am not entirely sure what you are suggesting....on approach flap alarms will be activated if no undercarriage is deployed infering the under carriage was deployed upon landing. A combination of computer or mechanical failure could have deceived the pilots on this.However I am not sure what degree of float would be experienced in these weather conditions. It could just be the pilots decided on a go around and was caught in a ground effect after raising the undercarriage at too lower altitude?
