Large Height Deviation (LHD) Report Template

            Experience has shown that large height deviations — errors of 90 m (300 ft) or more inmagnitude — have had significant influence on the outcome of safety assessments before and afterimplementation of RVSM. RMAs play a key role in the collection and processing of reports of suchoccurrences.Please find more details about the definition and classification of LHD event in Large Height Deviation Poster.

            Since 2007, China RMA has established the mechanism of LHD reporting over all en-route ATC departments, and the frequency of reporting is on a monthly basis. The controllers identify and confirm LHD occurrences during their daily work and report to their supervisors, after confirmation the detail of the event are reported to the point of contact of the responsible regional ATMB, who will then fill in the ATC LHD reporting template and submit reports to China RMA through the ‘China RMA Data Exchange Platform’.“Report Large Height Deviation (LHD) Report Template for ATC Department (Fill Specification)” has more details and is provided to refer.
