It encompasses a variety of systems, protocols, and technologies used to coordinate and manage the movement of aircraft in the airspace, both at various altitudes and across different regions and jurisdictions.

Fossil resins, commonly known as amber, are natural polymers that have undergone fossilization over millions of years. They originate from the resin secreted by various trees, particularly coniferous species, which is a sticky substance produced as a defense mechanism against pests or disease. Over time, the resin can become buried under sediment, and through processes such as heat and pressure, it hardens and transforms into a solid material.

Agarwood, also known as Oud or Aoud, is a highly valued and fragrant wood that is derived from the Aquilaria tree, particularly from species such as Aquilaria malaccensis. When the tree gets infected with a specific type of mold (Fusarium species), it responds by producing a dark, aromatic resin as a defense mechanism. This resin is what gives agarwood its distinctive scent and makes it so sought after.
