	Relaxed stability
		Lowering stability allows the plane to be designed purely for aerodynamic efficiency, as opposed to handling or "flyability", and can have noticeable performance improvements in some designs.
		Most older aeroplane designs are naturally stable across their entire performance envelope, allowing the aircraft to be flown without the pilot needing to constantly correct the flight path.
		Although such systems have been in use for many years in military aircraft, notably for yaw damping, the first true relaxed stability fighter was the F-16 Fighting Falcon, which used an advanced (for the time) flight control system that allowed the plane to fly very "flat" to the air as well, increasing performance and range.

	High-Altitude Handling
		For a statically stable airplane the required column force, as speed varies from the trimmed condition, is less at an aft CG than it is at a forward CG.
		Static longitudinal stability is a measure of the tendency of an airplane to maintain its trimmed angle of attack in 1g flight.
		It is a measure of the longitudinal stability tendencies of the airplane in other than 1g flight, and it accounts for the effects of pitch rate aerodynamic damping during maneuvering, as in the recovery from a pitch upset.

	Stability dependence of the relaxed eddy accumulation coefficient for various scalar quantities
		The coefficient b of the relaxed eddy accumulation (REA) technique was investigated by simulation studies using extensive high-resolution eddy correlation data sets of three different scalar quantities: the air temperature and the concentrations of CO and H
		The wide range of stability conditions during the experiment made it possible to describe the coefficient b as a function of the dimensionless stability parameter z/L within the framework of the Monin-Obukhov similarity theory.
		For stable conditions, however, a significant increase with stability was observed which could be well described by a logarithmic functional relationship between b and z/L.

	Hydrogen bonds shown to play 'conserved' role in protein folding
		By changing individual atoms in key places in proteins, Duke University chemists have found new evidence for the importance of comparatively weak "hydrogen bonds" in enabling stringlike proteins to fold into the maximally stable shape they need to assume their roles as biological workhorses.
		One by one, they slightly "mutated" the normal arrangement of atoms in proteins to effectively delete hydrogen bonds at five analogous positions along the structural "backbones" of two different protein molecules that fold in the same pattern.
		Protein stabilities were tested by measuring their responses to quanidinium chloride, a chemical used to make proteins unfold, or "denature."

	Dassault Falcon Aircraft / What's New / Falconer Online
		Fly-by-wire changes the rules slightly by permitting a state of "relaxed stability," which leaves room for the designer to reduce the size and weight of various aerodynamic surfaces, creating new efficiencies.
		The concept of static stability can be defined as the initial tendency of an object to diverge from or return to a state of equilibrium after having been disturbed.
		By relaxing the margins of stability on the Falcon 7X, aerodynamicists were able to optimize the performance of the airplane within those margins.

		Highlights of these tests included early and accurate projections of aerodynamic, stability, and control characteristics that allowed for resolution of problems before flight tests; rapid acceleration and validation of design methods for the avoidance of wing divergence for forward-swept wing configurations; and risk reduction for engine operations at high angles of attack.
		At low angles of attack, the model was very stable, with no tendency to oscillate or diverge (in agreement with the results of the dynamic force test).
		In the case of the drop model, when the angle of attack was increased to 30 deg and beyond, the oscillations became so divergent that the model exhibited uncontrollable 360-deg rolls that evolved into a roll departure and post-stall gyrations.

	Stability vs. Trimmability
		The relaxed stability and very strong controllability make it a highly maneuverable fighter-the airplane would be extremely difficult to control without the digital flight control computers.
		Static longitudinal stability is normally indicated in terms of stick force versus airspeed measured about a trimmed point of equilibrium.
		The level of positive stability is indicated by the degree of the slope of the curve.

	James S. Robbins on George W. Bush at National Defense University on National Review Online
		President Bush was signaling a historic development — the end of the stability paradigm, i.e., the belief that the objective of international politics is to keep the world in a steady state, blunting the impact of change and extinguishing crises as they arise.
		Hence the stability paradigm; since small crises can lead to the end of the world, they require the full attention of the international community to make sure that they do not spiral out of control.
		Stability became an objective, and in time took on the characteristics of a value.

		Stability is generally considered desirable, and contains all sorts of positive connotations.
		The paradox within "relaxed acoustics" is that by allowing a guitar to freely form many frequencies, you also make it less likely to prefer only a few.
		The main constructional tools available to the maker seeking "relaxed acoustics" are irregular distribution of mass, irregular distribution of stiffness, and asymmetry of design.

		Tilt stability is expected to occur when s < C Z/R_s, where C is an equilibrium dependent constant, Z is the half-height of the FRC, and R_s is the mid-plane radius of the separatrix.
		Initial results were presented of a nonlinear 3D code in cylindrical geometry for the stability studies of FRC, M3D-B. The code utilizes a MHD/particle representation in which background plasma is described by MHD equations and energetic ions are treated using particle simulations.
		Plans are to study the stability as a function of profiles, shape, and s as the energetic ion fraction increases, and for a fully kinetic ion description.

	X-29
		Conventionally configured aircraft achieved stability by balancing lift loads on the wing with opposing downward loads on the tail at the cost of drag.
		The No. 1 aircraft demonstrated in 242 research flights that, because the air moving over the forward-swept wing flowed inward, rather than outward as it does on a rearward-swept wing, the wing tips remained unstalled at the moderate angles of attack flown by X-29 No. 1.
		Phase 1 flights also demonstrated that the aeroelastic tailored wing did, in fact, prevent structural divergence of the wing within the flight envelope, and that the control laws and control surface effectiveness were adequate to provide artificial stability for this otherwise extremely unstable aircraft and provided good handling qualities for the pilots.

	Techniques To Improve Maneuver Stability Characteristics of a Nonlinear Wide-Body Transport Airplane in Cruise Flight, ...
		Abstract: The maneuver control stability characteristics of an aircraft are a flying qualities parameter of critical importance, to ensure structural protection as well as adequate predictability to the pilot.
		It is also recognized that additional engineering guidance is needed for identifying acceptable nonlinear maneuver stability characteristics, particularly as they relate to relaxed stability, highly augmented transport configurations.
		The objective of the present study was to evaluate a broad spectrum of linear and nonlinear longitudinal stability characteristics to generate data for defining satisfactory and unacceptable maneuver characteristics, as defined by pilot opinion.
