1 kwi 2018 · This paper studies the ability of the fuselage's lower lobe to absorb the energy during a crash landing, where the introduction of the composite materials can improve the crash survivability thanks to the crushing capability of structural parts to limit the effects of deceleration on the occupants.
scope: Q2507 is about unspecified movement of some passengers ("passengers moving around"). This would hardly be a problem. The scenario presented in this question here is an entirely different one, viz a hypothetical extreme case where ALL passengers gather in 1 spot at the front or back.
Thrust is the forward-acting force that opposes drag and propels the airplane forward. It is through excesses or deficits of thrust that accelerations and decelerations can occur. The aircraft will continue to speed up/slow down until thrust again equals drag, at which point the airspeed will stabilize.
20 lip 2023 · Specifically, we'll look at the relationship between mass, force, and acceleration through Newton's Laws, and how this affects the performance characteristics of an aircraft. These principles form a basis of understanding of the motion of any body with mass on Earth and so are directly applicable to operating a light aircraft.
18 sie 2018 · Due to the simple structure and lack of crashworthiness design in light airplanes, especially the considerations on impact energy absorption, an accident event usually causes significant harm to crews.
Mismanagement of mechanical energy (altitude and/or airspeed) is a contributing factor to the three most common types of fatal accidents in aviation: loss of control in-flight (LOC-I), controlled flight into terrain (CFIT), and approach-and-landing accidents. Thus, pilots need to have: An accurate mental model of the airplane as an energy system.
17 kwi 2006 · In most light planes, the shift is rearward with fuel burn. Its possible, then, to load an airplane within the center of gravity envelope for takeoff, only to have it move out of the envelope during flight. This can set up the pilot for a dangerous landing attempt.
