What Is a Touch-and-Go Landing?
Have you heard of touch-and-go landings? It’s a common flight maneuver performed by pilots in training. According to the Federal Aviation Administration (FAA), commercial pilots need 1,500 hours of training. During their training, many pilots will perform touch-and-go landings to … Read More
5 Facts About Composite Materials in the Aerospace Industry
Airplanes today are no longer made entirely of traditional metals and alloys. Many of them now feature composite materials in their construction. Composite materials are characterized by the use of multiple materials, such as a reinforcing fiber and a matrix. … Read More
Why Airlines Weigh Luggage
Weighing luggage is a common practice in the commercial aviation industry. Whether you’re taking a domestic or international flight, the airline will probably weigh your luggage prior to boarding. If your luggage exceeds the airline’s maximum weight, you may have … Read More
Why Do Airplanes Have Unusable Fuel?
