What happened
On 9 May 2016, an Airbus A319-111, registration G-EZFP, was prepared for a scheduled passenger flight from Lille Airport, France, to Toulouse. During the pre-flight phase, the crew used an Electronic Flight Bag (EFB) to determine takeoff performance. The commander, while reviewing runway options, compared the data for '08 T5' (Intersection Tango 5) against a temporary runway option, '08 TMP'.
While the crew focused on checking obstacles and stopway requirements related to a NOTAM regarding cranes, the commander selected the performance figures for the '08 TMP' option. This selection was subsequently cross-checked by the co-pilot, and the data was entered into the flight management guidance computer. The aircraft subsequently departed from Runway 08 using Intersection Tango 5, which provided significantly less runway length than the data used for the calculation.
After becoming airborne, the crew noticed that the runway end appeared closer than anticipated. Upon reviewing the EFB during the cruise phase, the commander identified that the runway lengths used in the calculation and the actual departure runway differed.
