The fly-by-wire system also allows automatic signals sent by the aircraft's computers to perform functions without the pilot's input, as in systems that automatically help stabilize the aircraft.

Some aircraft, the Panavia Tornado for example, retain a very basic hydro-mechanical backup system for limited flight control capability on losing electrical power, in the case of the Tornado this allows rudimentary control of the stabilators only for pitch and roll axis movements.

Reflections from terrain, water, and weather produce signals much larger than aircraft and missiles, which allows fast moving vehicles to hide using nap-of-the-earth flying techniques and stealth technology to avoid detection until an attack vehicle is too close to destroy.

This beam configuration allows the radar operator to detect an aircraft at a specific azimuth but at an indeterminate height.

Pilots of surviving or reproduction aircraft fitted with rotary engines still find, however, that the blip switch is useful while landing rotary-engined aircraft, as it allows pilots a more reliable, quicker source of power in case it should be needed, rather than risking a sudden engine stall at the worst possible moment.

They designed and built the radios that communicated the Apollo Moon landings and the high frequency radio network that allows worldwide communication with US military aircraft.

The capability to efficiently hover for extended periods of time is due to the helicopter's relatively long, and hence efficient rotor blades, and allows a helicopter to accomplish tasks that fixed-wing aircraft and other forms of vertical takeoff and landing aircraft could not perform at least as well until 2011.

This then allows airplanes to take the most direct approach path to the runway and land without worrying about interference from other aircraft.

In comparison to training in an actual aircraft, simulation based training allows for the training of maneuvers or situations that may be impractical ( or even dangerous ) to perform in the aircraft, while keeping the pilot and instructor in a relatively low-risk environment on the ground.

Its compact span for a given lifting area allows for great maneuverability and it is still used for aerobatics aircraft and crop dusting.

When an aircraft's lift is less than what is required for it to continue flying and stalls, ideally the nose should drop, which allows the aircraft to regain flying speed.

Perhaps the most important advantage to mounting the engines under the wings is that the total aircraft weight is more evenly distributed across the wingspan, which imposes less bending moment on the wings and allows for a lighter wing structure.

To enhance the effect of aerobatic maneuveres smoke is sometimes generated ; the smoke allows viewers to see the path travelled by the aircraft.

Although under ACC, it is best known for its role as the location of the Air Force Materiel Command's 309th Aerospace Maintenance and Regeneration Group ( AMARG ), better known as the sole aircraft boneyard for all excess military and government aircraft, as its location allows for preservation of the aircraft.

Davis-Monthan was selected due to its low humidity and hard, alkaline soil, which allows the aircraft to be naturally preserved for cannibalization or possible reuse.

In comparison to training in an actual aircraft, simulation-based training allows for the training of maneuvers or situations that may be impractical ( or even dangerous ) to perform in the aircraft, while keeping the pilot and instructor in a relatively low-risk environment on the ground.

A general aviation airport, Chester County G. O. Carlson Airport, which allows private and corporate aircraft to easily access the town, is located in Valley Township.

The horizontal stabilizer contributes extra stability and this allows the center of gravity to be a small distance aft of the aerodynamic center without the aircraft reaching neutral stability.

This combined with a large apron allows it to handle some of the world's biggest aircraft such as the Antonov An-124 or Boeing 747 Large Cargo Freighter, both types being frequent visitors.

A higher gear allows a cyclist to make fewer pedal turns to maintain a given speed, but with more effort per turn of the pedals.

All living canids ( Caninae ) have a ligament analogous to the nuchal ligament of ungulates used to maintain the posture of the head and neck with little active muscle exertion ; this ligament allows them to conserve energy while running long distances following scent trails with their nose to the ground.

* “ non-intrusive “ — the help menu must not interfere with the user ’ s primary path of work and must maintain a distance that allows for its use only when requested

The brain therefore exists in neutral buoyancy, which allows the brain to maintain its density without being impaired by its own weight, which would cut off blood supply and kill neurons in the lower sections without CSF.

A database management system ( DBMS ) is a system that allows to build and maintain databases, as well as to utilize their data and retrieve information from it.

While Gramsci's views argue that culture ( beliefs, perceptions and values ) allows the ruling class to maintain domination, Marx's explanation is along more economic lines, with concepts such as commodity fetishism demonstrating how the ideology of the bourgeoisie ( in this case, the existence of property as a social creation rather than an ' eternal entity ') dominate over that of the working classes.

A database management system ( DBMS ) is a system that allows to build and maintain databases, as well as to utilize their data and retrieve information from it.

A salt bridge allows the flow of ions to maintain a balance in charge between the oxidation and reduction vessels while keeping the contents of each separate.

This prevents all outsiders ( with hostile intent, or otherwise ) from approaching the planet and allows the Time Lords to maintain their status of absolute neutrality.

This is done to avoid catastrophic accidents caused by lack of knowledge / skill as much as possible, and also allows the government to maintain information on who reloads their own cartridges.

Along with helping IKEA make non-taxable profit, IKEA's complicated corporate structure allows Kamprad to maintain tight control over the operations of Ingka Holding, and thus the operation of most IKEA stores.

This gives laser light its characteristic coherence, and allows it to maintain the uniform polarization and often monochromaticity established by the optical cavity design.

Such superexploitation of the poor ( undeveloped ) countries allows the wealthy ( developed ) countries to maintain some homeland workers politically content with a slightly-higher standard of living, and so ensure peaceful labour – capital relations in the capitalist homeland.

International portability of social security rights allows international migrants, who have contributed to a social security scheme for some time in a particular country, to maintain acquired benefits or benefits in the process of being acquired when moving to another country.

Most structural proteins are fibrous proteins ; for example, actin and tubulin are globular and soluble as monomers, but polymerize to form long, stiff fibers that make up the cytoskeleton, which allows the cell to maintain its shape and size.

Power sliding allows a kart to maintain its speed while turning, although executing the maneuver for too long causes the kart to spin.

This, combined with swifter acceleration and braking, lets trams maintain higher overall speeds than buses, if congestion allows.

This allows winemakers to maintain the acidity levels that balances the fruity and flint earthiness that have characterized Washington Chardonnay.

This allows the drinker to regularly top-up the beer and thereby maintain a frothy " head.

PCAs facilitate the independence of their employers by assisting them with their daily personal needs in a way that allows them to maintain control over their lives.

This allows an organ to maintain constant flow despite a change in central blood pressure.

Anti-lock braking system ( ABS ) is an automobile safety system that allows the wheels on a motor vehicle to maintain tractive contact with the road surface according to driver inputs while braking preventing the wheels from locking up ( ceasing rotation ) and avoiding uncontrolled skidding.

This allows the animal to make dorsal turns and maintain a streamlined posture.

But fate – in the form of a sympathetic mayor and governor and their entourages – unexpectedly steps in and allows Annie to maintain her charade and keep Louise from learning the truth.

This type of fiber allows them to propel themselves forward at great speeds and maintain it for an extended distance.
