Pratt & Whitney’s GTF Advantage engine achieves FAA type certification

Aviation Bussiness News

With first production engine deliveries expected later in 2025, the GTF Advantage will provide 4-8% more takeoff thrust, enabling higher payload and longer range, unlocking new destinations for airlines. In the high-pressure turbine (HPT), the enhancements include an advanced airfoil design with improved coatings.

Tailless Aircraft: How Airplanes Fly Without a Tail

Pilot Institute

Use of Reflex Airfoils Ever notice how many tailless aircraft have wings that curve at the trailing edge? This type of design is a reflex airfoil. The reflexed shape of the airfoil usually causes a positive (nose-up) pitching moment coefficient at its aerodynamic center. Flying wings dont have tails or elevators.

Mach Number Explained: What It Is and Why Pilots Use It

Pilot Institute

For example, an airliner might indicate only 250 knots at 35,000 feet, but its true airspeed could be over 430 knots. Making the wing relatively flat on top with a blunter leading edge and more curvature on the bottom gives you a supercritical airfoil. Commercial airliners aren’t designed for supersonic flight.

Types of Pilot Licenses Explained (Student, Recreational, Private, Commercial, ATP, and more)

Pilot Institute

The requirement applies to private, commercial, and airline transport pilots, as well as flight engineers and navigators who fly internationally. While not a ticket to an airline job right away, a CPL allows you to earn money as a skydiving, photography, or pipeline patrol pilot among other entry-level aviation jobs. What does it take?

Is Flying a Helicopter Harder Than Flying a Plane? A Comparative Analysis

Pilot's Life Blog

The wings are designed with an airfoil shape, curved on the top and flatter on the bottom, creating a pressure difference when air flows over them. Each rotor blade acts as an airfoil, and as it rotates, it moves air over its surface, generating lift. This pressure difference produces lift, allowing the aircraft to ascend.
