Answer: In the PHAK handbook weight is also known as Mass or Force
Explanation:
The PHAK handbook is the Pilot’s Handbook of Aeronautical Knowledge, which is a reference book published by the Federal Aviation Administration (FAA) for pilots and aviation enthusiasts. It covers various topics related to flying, such as aerodynamics, aircraft systems, weather, navigation, and more.
In the PHAK handbook, weight is also known as mass or force. Weight is the force with which gravity attracts a body toward the center of the Earth. Mass is the quantity of matter in a body. The weight of an object varies with altitude and latitude, but its mass remains constant.
Weight is an important factor in aircraft performance, as it affects the lift, thrust, drag, and fuel consumption of an aircraft. Pilots need to calculate the weight and balance of their aircraft before each flight to ensure safe and efficient operation.
