NIFE AERO QUESTIONS AND ANSWERS RATED A+ What is a vector? direction and magnitude What is air density? Total mass of air particles per unit volume. m/v What is a moment? Force that is moved some distance. What are the requirements for an airplane to be in equilibrium flight? Sum of all forces and all moments around the center of gravity are equal to 0 Can equilibrium flight be achieved in a turn? No. Acceleration is occurring. There are moments What are the requirements for an a...

NIFE Aero Latest Version with Certified Solutions Define Vector A quantity that expresses both magnitude and direction. A vector quantity is represented by an arrow that displays direction and has a length proportional to magnitude Moment Force applied at some distance from an axis or fulcrum F x d (Distance: from the point of rotation that is perpendicular to force, "moment arm") Equilibrium Flight When the sum of all FORCE and all MOMENTS around the COG are equal to zero ...

AMT Airframe Written Test (FAA) Questions and Answers Already Passed What is the primary benefit of using composite materials in aircraft construction? They provide high strength-to-weight ratios and corrosion resistance, enhancing performance and longevity. How do winglets improve an aircraft's efficiency? They reduce induced drag by controlling the airflow around the wingtip, leading to better fuel efficiency. What is the purpose of the aircraft's pitot-static system? To m...

You climb to 17,000 feet in a turbocharged airplane and maintain the same true airspeed as you had been maintaining near sea level. What would you expect to observe about pitch attitude under these conditions? A-to maintain altitude, you need to maintain a more nose-high attitude because of the reduced air density compared to sea level B-to avoid climbing, you need to maintain a more nose-low attitude because of the reduced drag compared to sea level C-to maintain altitude, you need to ma...
