BangladeshNumber column of the Wikipedia list table under "Fixed Wing Aircraft". The list's own wording applies; it is a compiled secondary source, not an official census.
United StatesDirectory active-fleet estimate for the source types DHC-3, grouped under De Havilland Canada DHC-3 Otter. Sums only the listed service and role rows; includes training and special-mission versions where explicitly listed. Excludes the separate Ordered column, aircraft in storage, aircraft undergoing or awaiting upgrades, and the directory's other exclusions. This is the dated directory coverage of these types, not a complete owned-fleet census or a readiness count.
Reported count for NU-1B Otter. Service scope: Navy; does not replace a national total. 1 distinct quantity component(s) from the same source list; shared rowspan cells counted once. Explicit source inventory scope: active; no other stock status or total inferred. Count column(s): in service: 1. Origin: Canada. The listed variants/roles are the scope, not an immediately deployable count. The components do not establish one inventory census date; the stored date is the retrieved source snapshot.
