it was still saveable at that point if they had gone by the book.
This initial report into the 20 August accident states that the crew did deploy the flaps to an 11° position when the aircraft first left its gate at Madrid Barajas.
But after receiving departure clearance the crew opted to taxi back to the apron after reporting a technical fault with the ram air temperature probe. The probe had apparently heated to 105°C while the aircraft was still on the ground.
Electrical circuits normally supply heat to the probe only when the aircraft is airborne - this is determined by logic circuits using weight-on-wheels sensors in the nose-gear. The reason for the apparent logic mismatch remains under investigation.
Crucially the probe shares an electrical link with the configuration-warning system, as well as other functions on the aircraft, through a relay designated R2-5.
After the MD-82 returned to the apron to have the temperature probe checked, engineers reportedly disconnected a circuit-breaker in order to resolve the heating issue before clearing the flight to depart.
