How To Fly In Air? Flying, whether in a commercial airliner or a small aircraft, hinges on understanding fundamental principles of aerodynamics and flight controls; FlyerMedia.net can give you an overview. This article explores the forces at play, the controls pilots use, and some fascinating aspects of flight, like breaking the sound barrier, ultimately, we will share how aspiring aviators can learn flight at the best flight schools in the US.
1. What Exactly Is Air and How Does It Enable Flight?
Air is a physical substance possessing weight, and its molecules are in constant motion. Air pressure arises from the movement of these molecules. The force of moving air can lift objects like kites and balloons. Air, a combination of oxygen, carbon dioxide, and nitrogen, is essential for all forms of flight. It provides the power to push and pull on birds, balloons, kites, and planes. In 1640, Evangelista Torricelli’s discovery that air has weight laid the groundwork for understanding how it supports flight.
- Air’s Weight: Air is not weightless; it exerts pressure due to its mass and the constant motion of its molecules.
- Gas Composition: Air comprises various gases, including oxygen, nitrogen, and carbon dioxide, each playing a role in atmospheric properties.
- Air Pressure: The continuous movement of air molecules creates pressure, a critical factor in generating lift for aircraft.
- Force of Moving Air: Moving air possesses a force that can lift objects, as seen with kites and balloons.
- Torricelli’s Discovery: Evangelista Torricelli’s experiment in 1640 revealed that air has weight, influencing scientific understanding of atmospheric pressure and laying the groundwork for future aviation advancements. According to research from the University of Florence, in July 2023, Torricelli’s barometer experiments provided insights into air pressure and its effects.
2. How Do Airplane Wings Generate Lift?
Airplane wings are designed to make air flow faster over the top surface. Faster airflow results in lower air pressure. This means the pressure on top of the wing is less than the pressure underneath. The pressure difference creates a force that lifts the wing—and the entire aircraft—into the air. This principle, often referred to as Bernoulli’s principle, is fundamental to how airplanes achieve and maintain flight.

- Airfoil Shape: Airplane wings are shaped as airfoils, with a curved upper surface and a flatter lower surface.
- Bernoulli’s Principle: This principle states that faster-moving air has lower pressure.
- Pressure Difference: The faster airflow over the wing’s top surface creates lower pressure compared to the slower airflow underneath.
- Lift Generation: The pressure difference generates an upward force, known as lift, which counteracts gravity.
- Angle of Attack: The angle at which the wing meets the oncoming air also affects lift; a higher angle of attack can increase lift, but only up to a certain point.
3. What Are Newton’s Laws of Motion and How Do They Apply to Flight?
Sir Isaac Newton’s three laws of motion, formulated in 1665, are pivotal in explaining how airplanes fly.
- First Law (Inertia): An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by a force.
- Second Law (Acceleration): The acceleration of an object is directly proportional to the force acting on it and inversely proportional to its mass (F = ma).
- Third Law (Action-Reaction): For every action, there is an equal and opposite reaction.
- Inertia and Flight: A plane requires a force (thrust) to overcome its inertia and begin moving.
- Force and Acceleration: The thrust from an airplane’s engines must be strong enough to overcome drag (air resistance) and accelerate the plane to takeoff speed.
- Action-Reaction in Flight: The wings push air downward (action), and the air pushes the wings upward (reaction), creating lift.
4. What Are the Four Fundamental Forces of Flight?
There are four forces of flight that act on an aircraft in flight.
- Lift: The upward force that opposes weight, generated by the wings.
- Weight: The force of gravity pulling the aircraft downward.
- Thrust: The forward force produced by the aircraft’s engines, propelling it through the air.
- Drag: The backward force that opposes thrust, caused by air resistance.
| Force | Direction | Description |
|---|---|---|
| Lift | Upward | Opposes weight, generated by the wings |
| Drag | Backward | Opposes thrust, caused by air resistance |
| Weight | Downward | The force of gravity pulling the aircraft downward |
| Thrust | Forward | Produced by the engines, propelling the aircraft through the air |
- Lift vs. Weight: For an aircraft to take off and stay airborne, lift must be greater than or equal to weight.
- Thrust vs. Drag: To accelerate and maintain speed, thrust must be greater than or equal to drag.
- Balanced Forces: When all four forces are balanced, the aircraft maintains a constant speed and altitude.
**5. How Do Pilots Control an Airplane During Flight?
Pilots manipulate flight using controls that adjust the aircraft’s orientation in three dimensions: roll, pitch, and yaw. These controls include ailerons, elevators, and the rudder, allowing pilots to execute various maneuvers.
- Ailerons (Roll): Located on the wings, ailerons control the aircraft’s roll, enabling it to bank left or right.
- Elevators (Pitch): Found on the tail, elevators adjust the aircraft’s pitch, allowing it to climb or descend.
- Rudder (Yaw): Positioned on the tail, the rudder controls the aircraft’s yaw, directing the nose left or right.
6. How Do Ailerons Control the Roll of an Airplane?
To roll an airplane to the right or left, the ailerons are used. Raising the aileron on one wing and lowering it on the other causes the wing with the lowered aileron to rise, while the wing with the raised aileron drops. This differential lift creates a rolling motion.
- Aileron Movement: When the control wheel is turned clockwise, the right aileron raises, and the left aileron lowers.
- Differential Lift: The wing with the lowered aileron experiences increased lift, while the wing with the raised aileron experiences decreased lift.
- Rolling Motion: This difference in lift causes the aircraft to roll in the direction of the lowered aileron.
7. How Do Elevators Control the Pitch of an Airplane?
Pitch makes a plane descend or climb. The pilot adjusts the elevators on the tail to make a plane descend or climb. Lowering the elevators causes the airplane’s nose to drop, sending the plane into a descent. Raising the elevators causes the airplane to climb.
- Elevator Movement: Moving the control wheel forward lowers the elevators, while pulling it backward raises them.
- Pitch Adjustment: Lowering the elevators causes the airplane’s nose to drop, resulting in a descent. Raising the elevators causes the nose to rise, leading to a climb.
- Angle of Attack: Elevators control the angle of attack of the horizontal tail, which in turn affects the airplane’s pitch.
8. How Does the Rudder Control the Yaw of an Airplane?
Yaw is the turning of a plane. When the rudder is turned to one side, the airplane moves left or right. The airplane’s nose is pointed in the same direction as the direction of the rudder. The rudder and the ailerons are used together to make a turn.
- Rudder Pedals: The pilot controls the rudder using left and right pedals.
- Yaw Adjustment: Pressing the right rudder pedal moves the rudder to the right, causing the aircraft to yaw to the right. Pressing the left rudder pedal moves the rudder to the left, causing the aircraft to yaw to the left.
- Coordinated Turns: The rudder is used in conjunction with the ailerons to execute coordinated turns, keeping the aircraft aligned with its direction of travel.
9. What Instruments Do Pilots Use to Control an Airplane?
To control a plane a pilot uses several instruments…
- Throttle: Controls engine power. Pushing the throttle increases power, and pulling it decreases power.
- Control Wheel (or Stick): Controls the ailerons and elevators, affecting roll and pitch.
- Rudder Pedals: Control the rudder, affecting yaw.
- Brakes: Located on the rudder pedals, used to slow down the plane on the ground.
- Navigation Instruments: Radar Display, Direction Finder, Altitude Indicator.
| Instrument | Function |
|---|---|
| Throttle | Controls engine power |
| Control Wheel/Stick | Controls ailerons and elevators, affecting roll and pitch |
| Rudder Pedals | Controls rudder, affecting yaw |
| Brakes | Slows down the plane on the ground |
| Navigation Instruments | Radar Display, Direction Finder, Altitude Indicator. |

- Throttle Management: Pilots adjust the throttle to control engine power and maintain desired speed.
- Control Wheel Coordination: Pilots use the control wheel to manage roll and pitch, ensuring smooth and stable flight.
- Rudder Pedal Usage: Pilots employ rudder pedals for yaw control, particularly during turns and crosswind landings.
- Brake Application: Pilots use brakes to decelerate the aircraft on the runway, ensuring safe taxiing and stopping.
- Instrument Monitoring: Pilots continuously monitor navigation instruments to maintain situational awareness and adhere to flight paths.
10. What Is the Sound Barrier and How Do Airplanes Break It?
The sound barrier is the point at which an aircraft reaches the speed of sound, approximately 760 mph at sea level. As an aircraft approaches this speed, air compresses in front of it, forming a shock wave. To break the sound barrier, an aircraft must overcome this shock wave with sufficient thrust.
- Sound Waves: Sound is made up of molecules of air that move. They push together and gather together to form sound waves.
- Speed of Sound: Sound waves travel at the speed of about 750 mph at sea level.
- Shock Wave: When a plane travels the speed of sound the air waves gather together and compress the air in front of the plane to keep it from moving forward. This compression causes a shockwave to form in front of the plane.
- Sonic Boom: When the airplane moves through the waves, it is makes the sound waves spread out and this creates a loud noise or sonic boom. The sonic boom is caused by a sudden change in the air pressure.
- Mach Number: A plane traveling at the speed of sound is traveling at Mach 1 or about 760 MPH. Mach 2 is twice the speed of sound.
