a technical flight to land on the correct runway. The Polish State Commission on Aircraft Accidents Investigation made recommendations to add additional markings to the runway (in the form of red X shapes on the runway), and to modify the ATIS to include warnings about the closed runway. The CAT I ILS was disabled due to the construction, and the aircraft featured an older EGPWS that lacked a "Smart Landing" mode and high resolution map of the area which prevented it from informing the crew of the situation. During the approach, PAPI and threshold lights were set to maximum brightness. The incident is still being investigated by Polish authorities.
