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).
