DI-SESS-81450B, DATA ITEM DESCRIPTION: LOADS ENVIRONMENTAL SPECTRA SURVEY (L/ESS) DATA REPORT (24-MAY-2013) [SUPERSEDES DI-MGMT-81450A]., The Loads Environmental Spectra Survey (L/ESS) Data Report is used to present data collected from on-board flight data recorders which describes the actual operational loads environment of an aircraft. After statistical stability of the data has been achieved and if usage differences are apparent, an update of the baseline spectrum with current operational spectra derived from the L/ESS program may be necessary. a. The L/ESS Data Report Data Item Description (DID) is applicable to all programs as described in MIL-STD-1530. MIL-STD-1530 is applicable to all aircraft the USAF acquires, uses, or leases and L/ESS requirements can be tailored when appropriate. b. This DID contains the format, content, and intended use information for the data product resulting from the work task described in the contract per MIL-STD-1530. This DID supersedes DI-MGMT-81450A.
