This includes the human-machine interface. The way in which particular vehicle factors affect flying qualities has been studied in aircraft for decades, [3] and reference standards for the flying qualities of both fixed-wing aircraft [4] and rotary-wing aircraft [5] have been developed and are now in common use. These standards define a subset ...
In a statically stable aircraft of conventional (tail in rear) configuration, the tail-plane force may act upward or downward depending on the design and the flight conditions. [14] In a typical canard aircraft both fore and aft planes are lifting surfaces. The fundamental requirement for static stability is that the aft surface must have ...
To ensure stability for safe flight, an LSAS (Longitudinal Stability Augmentation System) was introduced to compensate for the MD-11's rather short horizontal stabilizer and ensure that the aircraft would remain stable. [8] However, there have been incidents in which the MD-11's relaxed stability caused an "inflight upset". [9]
An aircraft in cruise flight is typically speed stable. If speed increases, drag increases, which will reduce the speed back to equilibrium for its configuration and thrust setting. If speed decreases, drag decreases, and the aircraft will accelerate back to its equilibrium speed where thrust equals drag.
A Boeing 737 uses an adjustable stabilizer, moved by a jackscrew, to provide the required pitch trim forces. Generic stabilizer illustrated. A horizontal stabilizer is used to maintain the aircraft in longitudinal balance, or trim: [3] it exerts a vertical force at a distance so the summation of pitch moments about the center of gravity is zero. [4]
A yaw damper may remove the necessity for a pilot to make any contact with the rudder pedals during turns on a range of aircraft, including jet-powered ones. [2] [3] Some aircraft, such as the Boeing 727 and Vickers VC10 airliners, are fitted with multiple yaw damper systems due to their operation having been deemed critical to flight safety ...
A lack of new aircraft is painful. Despite the good news, with the expected increase in travelers, thin margins will still force airlines to search for lower costs. Plus, air travel is ...
An Air Malta crewman performing a pre-flight inspection of an Airbus A320.. Aviation safety is the study and practice of managing risks in aviation. This includes preventing aviation accidents and incidents through research, educating air travel personnel, passengers and the general public, as well as the design of aircraft and aviation infrastructure.
