Helicopters over Norway: ambulance, rescue and offshore
Who is flying low over the house at night? About the helicopters on the map, and why many of them are not shown.
Helicopters are the part of air traffic most often missing from real-time maps, and the part that most often makes people curious: who is flying low over the house at two in the morning? Here is who flies helicopters in Norway, how they are shown on Kartradar, and why many of them are not shown at all.
Who flies
- The air ambulance. Ambulance helicopters are based all over the country, with a doctor on board, and fly to accidents and acutely ill patients. They fly around the clock and at low altitude, often straight to a landing site at a hospital.
- The rescue helicopters. The large rescue helicopters of the Royal Norwegian Air Force fly search and rescue on land and at sea. They have bases along the whole coast and are tasked by the joint rescue coordination centres.
- Offshore. Helicopters run scheduled flights to and from the platforms on the continental shelf, carrying workers on shift. They fly from Sola, Flesland and Kristiansund, among other places, on fixed routes out over the sea.
- Police, power lines and cargo. Police helicopters, helicopters inspecting power lines, and helicopters lifting cargo to cabins, construction sites and mountain tops.
How to see them on the map
Helicopters are drawn with their own symbol: a helicopter seen from above, with a spinning rotor, in the same blue colour as aircraft. It is the helicopter itself that says it is a helicopter, in the ADS-B signal it transmits (the "rotorcraft" category). If it does not send that category, it is drawn as an ordinary aircraft.
When you tap the helicopter, the panel shows callsign, registration, altitude, speed and climb or descent rate, and the track it has flown.
Why many helicopters are missing
Aircraft positions are collected by volunteers with radio receivers, who pick up the signal the aircraft transmit. The signal follows the line of sight. An aircraft at 10,000 metres can be heard several hundred kilometres away, but a helicopter flying 150 metres above a fjord needs a receiver almost within sight.
That leaves three clear gaps:
- Low over land, between the mountains. Ambulance and rescue missions in fjords and valleys often disappear from the map until the helicopter climbs again.
- Far out at sea. Offshore helicopters are visible near land and disappear on the way out to the fields, where no receiver hears them.
- Helicopters that do not transmit a position. Military and some government helicopters often switch off ADS-B on missions, and older helicopters do not have it.
If you see a helicopter overhead that is not on the map, it is usually because no receiver nearby hears it. More about why aircraft are missing from the map.
How many there are
The number varies a lot through the day. On a Monday evening at nine in October 2026, three helicopters were visible over Norway on the map, out of around a hundred aircraft in total. During the day there are more, especially offshore. From October 2026 Kartradar counts the helicopters every five minutes, and the figures will appear in separate reports.
Altitude and speed
The altitude in the panel is barometric, measured with air pressure, just as for aircraft. Low over the ground it is therefore not necessarily the distance down to the terrain. Why altitude is not the distance to the ground. The speed is speed over the ground: a helicopter hovering in a strong wind can show zero.
A consideration
An ambulance or rescue helicopter on the map means someone needs help. The map shows where the helicopter is, never who the mission concerns. Call 113 in Norway for acute illness or injury, and let the rescue crews work in peace.
