Narrative:
After a flight from Palma de Mallorca to Porto, the crew of the Airbus A320-214 aircraft, registration HB-IOR, prepared the aircraft for the return flight. The necessary engine power for a takeoff on runway 17 was also calculated for the entire available runway length of 3480 m.
The crew then decided to takeoff from the intersection Foxtrot with an available runway length of 1900 m because air traffic control offered them the opportunity to overtake another aircraft, rolling in front of them, in the startsequence. The subsequent takeoff took place with the engine power which had previously been calculated for the entire runway length. This engine power was sufficient for a normal takeoff, but in the event of engine failure did not
meet the operational requirements for allowing the takeoff to be continued or rejected within the remaining runway length.
There was no damage. Flight AB7785 to Palma de Mallorca continued as planned.

Causes
The serious incident is attributable to the fact that the aircraft did not reach the necessary flight performance on takeoff, because the flight crew performed the takeoff from a runway intersection with an engine power which had been calculated for the entire length of the runway.

The following factors contributed to the serious incident:
 the fact that the commander was distracted by external circumstances during takeoff preparations;
 the uncomplete examination of the takeoff data within the frame of the "before start” checklist;
 procedures which stipulated individual checks only „if required”;
 the fact that essential checks were performed in silence.
