MANPADS (Man-Portable Air-Defense System)

MANPADS are short-range surface-to-air missiles, most commonly infrared-guided weapons that home on an aircraft's heat signature, though some use command guidance. Their portability is precisely what makes them a security concern: they can be moved, concealed and operated by a small group without fixed infrastructure. Their engagement envelope is limited in altitude and range compared with larger anti-aircraft systems, so the threat to civil aircraft is concentrated near airports and during climb-out and approach, when aircraft are low, slow and predictable.

The danger to civil aviation is driven less by the weapons' performance than by their proliferation. Large numbers have entered illicit circulation from conflicts and stockpile losses, raising the risk that they reach non-state actors operating near civil airfields or under flight paths. International efforts focus on stockpile security, transfer controls and threat reporting, while operators may adjust routing, approach profiles or destinations in response to credible MANPADS reporting in a region.

Because MANPADS exposure is geographic and altitude-dependent, it is most useful when tied to specific airports, approach corridors and conflict areas. Within an aviation security intelligence picture, a platform such as AeroVigil can associate reporting on weapon proliferation and conflict activity with the routes and terminal areas where the lower-altitude threat would actually apply.
