Editing Unit load device (section)

==Identification==
[[File:ULD nomenclature.svg|thumb|right|Dimension names of ULD (LD3/AKE shown)]]
All ULDs are identified by their ULD number. A three-letter prefix identifies its type and key characteristics,<ref name=VRR-IATA-ULD>{{cite web |url=https://vrr-aviation.com/uld-info/uld-id-code/ |title=Identifying a Unit Load Device |publisher=VRR Aviation |access-date=21 February 2019}}</ref> followed by a 4 or 5 digit serial number (4 if prior to October 1, 1993; either 4 or 5 if after October 1, 1993) to uniquely identify it from others of the same type, and ending with a two character (alpha-numerical) suffix identifying the ULD's owner (if an airline, often the same as [[IATA]] designator codes). For example, ''AKN 12345 DL'' means that the ULD is a forkliftable LD3 with the unique number ''12345'' and its owner is [[Delta Air Lines]].<ref name="Air_Cargo">
