What Is Adverse Yaw and What Causes It?

Have you heard of adverse yaw? Yaw, of course, is one of the three axes of flight. It represents the oscillation or rotation of an object, such as an airplane, around a vertical axis. Pilots can control the airplane’s yaw … Read More

Why Airplanes Use Knots Instead of MPH

Ever wonder why airplanes use knots to measure their speed instead of MPH? The speedometers in cars, trucks and other land-based vehicles display speed in MPH. The airspeed indicators in airplanes, however, display speed in knots. What Is a Knot? … Read More

How Retractable Landing Gear Works

Ever wonder how retractable landing gear works? With the exception of small private airplanes and commuter airplanes, most airplanes don’t have fixed landing gear. Instead, they have retractable landing gear. Their landing gear systems are concealed within the belly of … Read More

Alternative Wing Configurations: What Is a Canard?

Not all airplanes have a traditional wing configuration consisting of a single horizontal wing around the middle of the fuselage. There are alternative wing configurations available, one of which is a canard. Canards are commonly found on military jets. Some … Read More

What Are Autobrakes on Airplanes?

Modern-day airplanes are designed with a variety of automated systems. In addition to autopilot, for instance, many of them feature an automatic braking system. Known as autobrakes, it’s used during landings and rejected takeoffs. To learn more about autobrakes and … Read More

Do Airplanes Fly Faster at Higher Altitudes?

Ever wonder if the altitude at which an airplane flies affects its speed? Most commercial jets have a cruising altitude of 31,000 to 42,000 feet. After taking off, they will climb for about 10 minutes to reach this altitude. Yes, … Read More

Zero Fuel Weight Explained

Zero fuel weight is an important metric for fixed-wing aircraft. Not to be confused with maximum takeoff weight (MTOW), it represents the total weight of an aircraft minus fuel. Whether you’re a private pilot or aerospace engineer, you can’t ignore … Read More

Aircraft Fuel Systems: What Is a Header Tank?

Aircraft fuel systems are more complex than their automotive counterparts. While most cars, trucks and other automobiles have a single fuel tank, large commercial airliners typically have at least two fuel tanks. The Boeing 787, for instance, has three fuel … Read More

5 Facts About Airplane Wing Spoilers

When most people think of spoilers, they envision the wing-like structures found on the back of sports cars. Spoilers such as these are common. They are aerodynamic devices that disrupt or “spoil” the airflow, resulting in better performance. But spoilers … Read More
