Here’s the text to the listening from yesterday.
An A320 taxied towards the runway for takeoff. Their taxi instructions led them to join the runway via a taxiway which gave them only 60% of the available runway for takeoff. The crew however, had configured the plane for takeoff using 100% of the runway length. As they rolled for takeoff they were unable to achieve the performance necessary due to the reduced runway available, but fortunately they were able to takeoff without incident and completed a safe flight after that. The aviation authority is investigating what happened.
