What Do Police Helicopters Do? & More | Explained
What exactly is the purpose of that whirring machine circling overhead, a ubiquitous presence in our skies? Police helicopters, a common sight, are far more than just aerial observers; they represent a multifaceted tool in modern law enforcement.
If you've noticed a police helicopter diligently circling your neighborhood, it's likely engaged in a specific operation, or perhaps even several simultaneously. Law enforcement agencies employ helicopters for a diverse range of tasks, designed to enhance public safety and investigative capabilities.
So, what are these tasks?
Helicopters are often utilized for patrol and surveillance. From a vantage point, they can monitor vast areas, providing officers with a comprehensive view of ground-level activities. This is particularly useful for identifying potential criminal activity, tracking suspects, and providing real-time information during emergencies. Equipped with advanced cameras and sensors, these aircraft can capture high-resolution images and video, contributing vital evidence in criminal investigations.
Search and rescue missions represent another critical function. When time is of the essence, helicopters provide rapid access to remote or inaccessible locations. Their ability to hover allows for precise positioning during rescue operations, while their maneuverability makes them ideal for navigating challenging terrain. Helicopters are often equipped with specialized equipment, such as hoists and medical supplies, enabling them to extract injured individuals and provide on-site medical assistance.
The versatility of police helicopters also extends to supporting ground units during active situations. They can provide aerial support during pursuits, assisting in tracking suspects and coordinating the actions of officers on the ground. In the event of a natural disaster or major incident, helicopters are essential for damage assessment, providing situational awareness to emergency responders and assisting in the distribution of aid.
Beyond these core functions, police helicopters contribute to a variety of additional tasks. They may be involved in traffic monitoring, identifying traffic congestion, and assisting in accident investigations. They are used for aerial photography, documenting crime scenes, and creating records of evidence. Helicopters often play a role in transporting personnel and equipment, enhancing the efficiency of law enforcement operations.
The helicopter itself is an engineering marvel, offering capabilities that traditional airplanes simply can't match. Lets take a closer look at the science behind the machine.
A helicopter's rotors are the key to its unique capabilities, allowing it to perform maneuvers impossible for fixed-wing aircraft. Unlike an airplane, which depends on forward motion to generate lift, a helicopter does not require speed to stay aloft. This fundamental difference gives helicopters a distinct advantage in certain operational scenarios.
The fact that a helicopter can generate lift without forward motion means it can move straight up or down. Most airplanes cannot do this. The ability to take off and land vertically, without the need for a runway, opens up a world of possibilities for helicopters. They can operate in confined spaces, such as densely populated urban areas or mountainous regions, where traditional aircraft are unable to operate safely or efficiently.
When it comes to aircraft, helicopters are in a league of their own. Unlike airplanes, which require a runway to take off and land, helicopters possess the extraordinary ability to do both vertically. This capability helps helicopters operate in environments that are inaccessible to airplanes, such as dense urban areas, mountainous terrain, and areas affected by natural disasters.
The core of a helicopter's operation lies in its ability to manipulate air currents. A rotating set of blades, known as rotors, acts as a spinning wing, generating lift as they move through the air. The pilot has precise control over the angle of these blades, which determines the direction and magnitude of the lift produced. By adjusting the pitch of the blades, the pilot can control the helicopter's ascent, descent, and horizontal movement. The rotor of this seahawk helicopter is spinning on the silver shaft on the right of the photo.
In addition to the main rotor, located on the top of the aircraft, helicopters also typically have a tail rotor. The tail rotor counteracts the torque generated by the main rotor, which would otherwise cause the helicopter to spin uncontrollably. The tail rotor allows the pilot to control the direction of the helicopter's yaw, enabling it to move sideways or rotate in place.
The mechanics of helicopter flight is a delicate dance of forces. The pilot uses three primary controls to maneuver the aircraft. The collective lever, located to the pilot's left, adjusts the pitch of the main rotor blades, controlling the overall lift of the helicopter. The cyclic stick, positioned between the pilot's legs, is used to tilt the rotor disc, determining the direction of movement. The pedals control the pitch of the tail rotor blades, controlling the helicopter's yaw.
Although some small helicopters still use piston engines (also called reciprocating engines, similar to the ones used in cars and trucks), most now use gas turbines more like the jet engines on conventional airplanes. Helicopters are remarkably versatile machines. They can do many things that airplanes cannot.
The operation of a helicopter is undeniably complex, but it's also a testament to human ingenuity and a symbol of the advancements in modern aviation. Whether it's a police helicopter patrolling the city skyline, a rescue helicopter assisting in a disaster, or a civilian helicopter transporting passengers, these machines are constantly at work.
A fascination with flight has captivated people for generations. From the earliest attempts to soar through the air to the sophisticated technology of modern aircraft, humans have strived to achieve the dream of flight. One aspect of this enduring fascination is the world of aircraft dispatchers. Whether you are interested in becoming an aircraft dispatcher for traditional airplanes or helicopters or if you are just curious about how they work, the world of aviation is an exciting field.
How fast do helicopters fly? This is a common question, and the answer depends on the specific type of helicopter and the conditions of flight. However, most helicopters typically cruise at speeds ranging from 100 to 170 miles per hour. This speed is slower than that of conventional airplanes, but the helicopter's ability to take off and land vertically and its maneuverability make it a valuable asset in many situations.
Unlike airplanes, helicopters use rotors instead of wings to generate lift. The rotors, rotating blades on top of the aircraft, create a downward airflow, generating an upward force that counteracts gravity and allows the helicopter to take off and stay airborne. This unique design is what sets helicopters apart and gives them their exceptional capabilities.
The helicopter's rotors perform the same function as an airplane's wings: to provide lift. The rear rotor can face different directions, allowing the helicopter to move forward, backward, and sideways. A #helicopter has no wings, but still manages to fly. And you need three different controls to do it! See how it all works!

Let's take a moment to step away from the technology and talk about fun: the helicopter dance move. It is a simple yet entertaining dance move that can be fun to perform.
Watch a guy perform the helicopter dance move. You take a deep breath and first you use your own hand to get it going the correct direction while your hips are going the same direction. Once you feel you can take off the training wheels, let loose. Try this method at least a few times and in no time you'll be doing the helicopter like a professional.
