On preflight we noted a shortened runway due to a displaced threshold. My copilot called airport and received additional information on construction and NOTAM's we already had received during preflight. Upon arrival we were asked if we were aware of the shortened runway and copilot replied with an affirmative. We touched down and made a normal landing and were told we had landed inside the displaced threshold. The copilot and myself never saw any indicators that a pilot normally looks for on a displaced threshold. There were no obvious markers leading to where the threshold starts. As a crew we feel we did everything to prepare for the flight and never saw exactly where the threshold began or anything to lead to it. The only obvious thing on the runway was a tarp over the numbers. We feel thresholds need to be marked clearly so high performance jets can have a clear aiming point.
The reporter state that the only indication of the location of the displaced threshold were two traffic cones placed on either side of the runway.
CE650 Captain reports being aware of a NOTAM for AHN creating a 1;500 foot displaced threshold for Runway 27. The reporter is informed after landing that he touched down in the displaced threshold. Nonstandard displaced threshold markings were cited as the cause.
