Definition
Shoulder-fired surface-to-air missiles capable of being carried and launched by a single person, typically using infrared (heat-seeking) guidance to track and engage low-flying aircraft. MANPADS represent a recognized terrorist threat to civil aviation, particularly during low-altitude phases of flight such as departure and arrival.
Plain English
A small, shoulder-launched missile that one person can carry and fire at an aircraft. It locks onto the heat from the engines and is most dangerous to aircraft flying low and slow.
Context Anchor
Pilots may see this term in aviation security information, threat briefings, or flight planning material involving risk near an airport or along a route.
Derivation
The name is purely descriptive: 'Man Portable' meaning carried by one person, 'Air Defense' meaning shooting down aircraft. The term was coined by the military to distinguish these from larger, vehicle-mounted or fixed surface-to-air missile systems.
Why Pilots Care
MANPADS represent a serious, hard-to-detect threat to low-altitude flight; awareness helps pilots follow routing restrictions and security guidance that reduce exposure.
Intuition Check
Do not read “portable air defense” as general safety equipment or airport protection gear. In this context, MANPADS means portable missile weapons that can threaten aircraft.
Example Sentence 1
A suspected MANPADS sighting near the departure end of Runway 27 prompted ATC to hold all departures until law enforcement cleared the area.
Example Sentence 2
After the security briefing, the crew adjusted altitude to stay outside MANPADS engagement range.
