Soaring facts for kids

Kids Encyclopedia Facts

Soaring is a special kind of flight where an aircraft or a bird flies without using an engine. Instead, it uses natural movements of air to stay up in the sky. Think of it like riding an invisible elevator of air! This amazing skill allows birds to travel long distances and people to enjoy silent flights in gliders, hang gliders, and paragliders.

How Does Soaring Work?

Soaring is all about finding and using air that is moving upwards. There are a few main ways this happens:

Thermal Lift

Imagine the sun heating up the ground. Some parts, like a dark field or a paved road, get hotter than others. This hot ground then warms the air above it. Warm air is lighter than cool air, so it starts to rise, forming a big bubble or column of air called a thermal. Pilots and birds look for these thermals and circle inside them, riding the rising air higher and higher, just like a bubble in water.

Ridge Lift

When wind blows against a hill or a mountain, it has nowhere to go but up and over the obstacle. This creates a steady upward flow of air along the side of the ridge. Glider pilots and birds can fly back and forth along these ridges, staying airborne as long as the wind keeps blowing. It's like surfing on a wave of air!

Wave Lift

Sometimes, when strong winds blow over a mountain range, they can create invisible waves in the air on the other side. These are called mountain waves. Pilots can fly into these waves and climb to very high altitudes, sometimes even above the clouds. This type of lift is often very smooth and powerful.

Who Soars?

Many different creatures and machines use soaring to fly.

Birds That Soar

Many large birds, like eagles, hawks, vultures, and albatrosses, are masters of soaring. They have wide wings that help them glide efficiently. By finding thermals or using ridge lift, they can spend hours in the air without flapping their wings much, saving a lot of energy. This helps them search for food or travel long distances.

Human Soaring Sports

People have learned a lot from birds and have developed special aircraft to soar.

Gliding

A glider (also called a sailplane) is an aircraft with long, slender wings and no engine. It's usually launched into the air by being towed by another airplane or by a winch. Once airborne, the pilot searches for thermals or other types of lift to stay in the air. Gliding is a quiet and peaceful sport, allowing pilots to fly for many hours and cover hundreds of kilometers.

Hang Gliding

A hang glider is a lightweight, unpowered aircraft that looks a bit like a large kite. The pilot hangs underneath the wing in a harness and controls the glider by shifting their body weight. Hang gliders are often launched by running off a hill or mountain. It's a thrilling way to experience flight, feeling the wind and air currents directly.

Paragliding

A paraglider is a fabric wing, similar to a parachute, but designed for soaring. The pilot sits in a harness suspended below the wing. Like hang gliders, paragliders are usually launched by running off a slope. They are very portable and allow for a very close connection to the air, making it a popular adventure sport.
