All airports with ATC control towers in the U.S. (and some non-towered airports) use a standard set of pavement markings and elevated signs to guide pilots from the parking airport to the active runway. Test your knowledge of their location and meaning in this interactive exercise so that you’ll be well prepared on what to expect when taxiing at a large airport.

Calculating the airplane's weight and balance is a mandatory task you must complete before every flight. Many of an airplane's performance, handling, and structural characteristics are a function of weight and balance, not to mention the safety risks associated with operating an overloaded or out-of-balance airplane.

Aircraft engines can provide thousands of hours of reliable service, provided that they are maintained and operated properly. From the pilot's perspective, this involves learning the best practices for power control, leaning procedures, cooling, and other operational considerations.
