Airplane Landing

Target Landing Time (TLDT) is the Targeted Time from the Arrival management process at the threshold, taking runway sequence and constraints into account. It is not a constraint but a progressively refined planning time used to coordinate between arrival and departure management processes.

Each TLDT on one runway is separated from other TLDT or TTOT to represent vortex and/or SID separation between aircraft.

TLDT is a term specified in the Airport Collaborate Decision Making (A-CDM). It is one of several terms related to Landing Time (LDT).
