We have been made aware of the PKWA (Bucholz Army Airfield Kwajalein Island) runway being shortened from 6;668 feet to a new LDA (Landing Distance Available); ASDA (Accelerate-Stop Distance Available); TORA (Takeoff Run Available); and TODA (Takeoff Distance Available) to 6;058 feet. This is due to what has been called a 'displaced threshold' on both ends of the runway. However; I was expecting pavement from the start of the original Runway 6 with chevrons or similar markings as per the AIM. However; what I saw on final was the first 400 feet of Runway 6 is now coral; gravel; and dirt...not pavement. It is not a displaced threshold; the runway now actually starts 400 feet further down the island. There are temporary lights placed on the pavement to indicate the starting edge of the new runway edge. The approach end of Runway 24 has been displaced 140 feet and still has pavement that is repainted with a temporary threshold and is marked with temporary lighting as well. The performance on the Takeoff Data Message has been adjusted correctly. The PAPI are out of service as well to ensure you are not guided into an early landing as well. Don't expect a displaced threshold on Runway 6 per the NOTAM; expect a new start to the runway surface.
