Displaced threshold

A preliminary NTSB report on last month’s fatal Citation crash at Conway Municipal Airport in Conway, Ark., said a witness reported seeing the aircraft land long and then the pilot “added power at the last second, lifted the nosewheel off the ground and struck the [jet-blast deflector]” situated at the end of the runway.

About six months ago, someone–either a customer or an aircraft manufacturer–queried Rockwell Collins about a runway with a displaced threshold in a Pro Line FMS database. The airport databases in FMSs used in the Pro Line 4 and 21 avionics suites provide total runway length but not available landing distance (runway length less displaced threshold or usable length).
