Advantages Of Using Helicopters For Utility Inspections
Helicopters are a better option for longer distance inspections, can carry larger payloads, and have more experienced pilots who provide greater stability in adverse weather conditions, which is essential to cover larger geographic areas of utility inspection.
Ability To Cover Larger Geographic Areas
One clear advantage of using helicopters for utility inspections is their ability to cover larger geographic areas. Helicopters can fly at higher altitudes and travel faster than drones, allowing them to inspect vast utility fields or pipelines in a shorter amount of time.
This makes them the preferred option for long-distance inspections or surveys that require covering large expanses of land. For instance, helicopters are ideal for powerline inspections across mountainous terrains where rugged terrain and elevation changes make ground inspection impossible.
Helicopters Can Carry Larger Payloads
One of the biggest advantages of using helicopters for utility inspections is their ability to carry larger payloads compared to drones. Helicopters can transport heavier equipment and personnel, making them ideal for conducting complex and detailed inspections in challenging locations.
For example, during power line inspections in mountainous areas or rough terrain where access by land can be difficult or impossible, a helicopter’s payload capacity allows it to transport personnel and specialized equipment more efficiently than a drone.
Additionally, its ability to lift heavy equipment such as transformers ensures that comprehensive assessments are completed in one operation, saving time and reducing costs.
More Experienced Pilots
Another advantage of helicopters for utility inspections is the availability of more experienced pilots who have specialized in such utility inspection operations for years. These skilled pilots have extensive training and knowledge to handle complex and challenging situations, such as flying in adverse weather conditions or dealing with unexpected mechanical issues during flights.
Greater Stability In Adverse Weather Conditions
Helicopters also have better suitability to operate in certain adverse weather conditions in comparison to drones. Helicopters are designed to deal with harsh weather environments to a certain extent, which drones may struggle with due to their smaller size and lightweight construction.
This means that during emergency outage situations caused by extreme weather events, a helicopter may be the best option for inspecting power lines quickly and efficiently.
