Definition
A service in which an air traffic controller provides radar headings and altitude information to a pilot in distress, using an Emergency Obstruction Video Map (EOVM) to keep the aircraft clear of terrain and obstructions during an emergency that requires descent below the minimum vectoring altitude.
Plain English
When something has gone wrong and a pilot needs to fly lower than normally allowed, the controller uses a special map showing terrain and tall obstacles, and gives the pilot headings and altitudes that keep the aircraft safely away from them.
Context Anchor
Seen in discussions of the Emergency Obstruction Video Map, which helps controllers provide safer heading guidance during emergencies.
Derivation
‘Vectoring’ comes from the Latin ‘vector,’ meaning ‘carrier’ or ‘one who conveys’ — in aviation it refers to a controller giving the pilot a heading to fly. ‘Emergency vectoring’ simply means that vectoring service is being used in an emergency situation, where the normal altitude protections may need to be set aside to help the pilot.
Why Pilots Care
Provides immediate, precise guidance that can prevent controlled flight into terrain when a pilot is lost, disoriented, or flying in instrument conditions near high ground.
Grounding Statement
Picture a pilot in an emergency asking ATC for help, and the controller using radar and obstacle information to say which way to turn next.
Intuition Check
Do not assume “service” means ATC takes over the flight or guarantees safety. The controller provides urgent guidance, but the pilot still flies the airplane and remains responsible for accepting or rejecting a heading if it is unsafe.
Example Sentence 1
After losing cabin pressure, the crew declared an emergency and requested emergency vectoring service for an immediate descent.
Example Sentence 2
After declaring an emergency, the pilot accepted emergency vectoring service to reach the nearest suitable airport.
