What does a yellow helicopter mean? Are you curious about the Yellow Helicopter Flying Low Meaning? The helicopters belong to Western Power Distribution who are carrying out routine checks on power lines in the city.
They can survey about 130km to 160km of line during a normal five-hour flying day split into two sorties.
“The larger machines have also been equipped with special capabilities for stringing of lines which can help make the task much more efficient and also avoid any risk of land damage.”

Yellow Helicopter Flying Low Meaning
The helicopters are used primarily within the electricity distribution industry for the maintenance and repair of networks, and also during emergency and fault conditions.
A Western Power spokeswoman said: “I can confirm that a WPD helicopter was flying over Market Bosworth on Wednesday.
“The helicopter was carrying out an inspection of local power lines following reports of a fault.
“The crew successfully identified the cause of the fault and this is now being resolved by WPD engineers.”
She added that the aircraft flew from Bristol directly to Market Bosworth before returning to the south east, however, the helicopters can land if necessary at local airports.
WPD’s Helicopter Unit is operated by a staff of five pilots, six observers, four assistant observers and three maintenance engineers under the charge of manager Robin Tutcher.
The team operates out of a specially constructed hangar and offices at Bristol Airport.
Robin said: “The crews are highly skilled and experienced and notch up a total of over 3,000 flying hours annually inspecting approximately 50,000kms of network.
“They will ultimately decide if bad weather such as high winds, poor visibility or heavy rain makes flying hazardous or impractical.
“We know we can rely on each other to get the job done safely and efficiently which is very important.”
Routine Visual Line Patrol
“This makes up 70% of our work. The helicopter flies just above and to one side of the line. Trained observers, using OS maps with overlays showing power lines and installations, report on 40 kinds of faults – ranging from deterioration to damage caused by storms, vandals and woodpeckers. If the condition is urgent, details are immediately telephoned to our electricity network control centre.
“All routine work is plotted onto report maps or stored in a computer system.
“About 130 to 160 km of line can be surveyed in a normal five-hour flying day split into two sorties. Two men and a Land Rover would take 10 days.”
Thermal Line Patrol
“A forward looking infra-red Kelvin 275 electronic camera is used with a digital video recorder to detect hot spot faults. Used mainly on the 132kV and 33/66kV systems, this technique can also show heat coming from buildings to measure how energy efficient they are. Utilising superior four-axis stabilisation, this camera system delivers exceptional TV performance, together with the latest technology in thermal imaging.
“The system also gives advance warning of potential faults, helping to improve fault records, and ensures that we have an effective preventative maintenance policy.”
Lifting and Stringing
“All WPD helicopters have external lift capability of up to 750 kg, depending on fuel requirements. This work includes lifting and planting poles, lifting transformers and stringing conductors.”
Transportation & Ferry Flights
“This service covers any flight that is not line patrol and saves considerable time and money.
The helicopters can carry up to six passengers and provide an excellent aerial platform for photographic, video and film work.”
Emergencies & Post-Fault Patrols
“This is probably the most effective use of helicopters. The Unit has a great deal of experience in adapting to all kinds of emergency conditions. Some of the many tasks undertaken include detailed inspection, transporting work teams and equipment to difficult sites, lifting and construction.138212091369
“Our contribution has often been a major factor in restoring electricity supplies as quickly as possible. We can also provide a quick response to requests for post-fault patrols. Reports are regularly available within three hours of a request for help.
