Abstract: An aircraft pallet assembly structured to support and retain cargo intended to be loaded on and transported by commercial aircraft, wherein the pallet assembly comprises a base and a surrounding peripheral portion normally including a multi-sided configuration. Each side of the base includes a peripheral flange extending at least along a majority of the length thereof, which is disposed and configured for fixed attachment to one of a plurality of track segments, collectively defining a track assembly, and structured to removably secure a load retaining assembly, typically in the form of a retaining cover or net in overlying, covering relation to the cargo, for purposes of maintaining the cargo in an intended position on the base of the pallet assembly.
