Departing off Rw 23 operating QTR915 (callsign QTR19Q) to Doha. At the time of writing, due to taxiway L2 works impinging on the main runway, 05/23, at the 23 end, a displaced threshold was in effect shortening the operational length of the runway by approximately 3,800 ft. During the period of the displaced threshold, Qatar Airways replaced their DOH-ADL-DOH A359 services with their long range B772s.
