Dictionary Of Aeronautical Terms

The difference in pressures is calibrated as air speed by a panel instrument. Of or pertaining to the air, atmosphere, or aviation.

Spectral absorptance refers to absorptance measured at a specified wavelength. Each line is associated with a particular mode of electronic excitation induced in the absorbing atoms by the incident radiation. Compare to visual flight rules. The decay time involved is a direct consequence of the charged particle loss mechanisms, such as diffusion and recombination.

An aeroplane with one wing or pairs of wings. Also called otitic barotrauma. In other languages Add links.

Definition from Wiktionary, linguaphone spanish the free dictionary. Please read the Introduction to find out about this dictionary and our plans for it. Dictionary of Aeronautical Terms. Alert Areas are depicted on aeronautical charts for the information of non-participating pilots.

The angle that an aeroplane's wings make relative to the lateral axis horizontal plane, when on level ground. Pilot or crew of lighter-than-air craft.

Study On-The-Fly

The term was borrowed from boat builders. Compare scattering cross section.

The direction in which the aircraft is moving, not to be confused with the heading which is the direction the aircraft is pointing. Branch of a country's military devoted to air warfare. The problem of the effect of reentry on the trajectory of a vehicle is a problem in aeroballistics. Direction of travel is upward and outward from the fuselage to the interplane struts.

In theory, no absolute coordinate system can be established because the reference stars are themselves in motion. Increased lift is usually achieved by increasing the wing area and the camber shape of the wing to a lesser extent. Direction of travel is downward and outward from the fuselage. Hover Out of Ground Effect.

In Britain, an alternative term for airport. Target distance is indicated by the horizontal position of the deflection from one end of the time base.

The Pitot tube is named after its inventor, Henri Pitot, and was modified to its modern form by Henry Darcy. This term is generally considered out-of-date. Description Specifications Reader Resources. The load factor necessary for an airline to break even.

The point at which the mass of the aircraft would be balanced if it were placed on that single point. The act or process of accelerating, or the state of being accelerated. Irregular burning of fuel left in the firing chamber or a rocket after fuel cutoff. The modern term is airship. Also called perfect vacuum.

Its lift is caused by buoyancy relative to the surrounding air. The vertical component of the absolute vorticity as defined above. Compare to instrument flight rules. The course is also different from the track which is properly the path over the ground that the aircraft has already flown although course and track are sometimes used synonymously. It was a principal reason for pressurized aircraft.

Study On-The-Fly

Vertical Speed Indicator, shows the rate of climb or descent. Also called absorption factor. Also called index of absorption. Primarily single-occupant vehicles, although some two-place vehicles are authorized for training purposes. Note that this is not necessarily the same as the aircraft's heading.

Aeronautical

The paved area at an airport. The purpose of such warning area is to warn non-participating pilots of the potential danger. Negative acceleration is called deceleration. Each line is associated with a particular mode of vibration or rotation induced in a gas molecule by the incident radiation. The transient decay of a plasma after the power has been turned off.

We will post new information and terms here as applicable. Ferry flights, under certain conditions, may be conducted under terms in a special flight permit. Adcock antenna A pair of vertical antennas separated by a distance of one-half wavelength or less, and connected in phase opposition to produce a radiation pattern having the shape of a figure eight.

Flightline Tarmac The Prop Shop. Includes helicopters and gyroplanes. Now outdated by more sophisticated means. The spectrum formed by a selectively absorbing liquid or solid is typically continuous in nature continuous absorption. High adaptation luminance tends to produce a high threshold contrast, thus reducing the estimated visual range.

Also called oculoagravic illusion. The vorticity of a fluid particle expressed with respect to an absolute coordinate system.

Increases in steep turns and other abrupt manouvers. The final and initial temperature in an adiabatic, Carnot cycle.

Dictionary of Technical Terms for Aerospace Use - A

An absorption spectrum formed by a monatomic gas exhibits discrete dark lines, whereas that formed by a polyatomic gas exhibits ordered arrays bands of dark lines, which appear to overlap. Caution, many entries have not been updated since the edition. The stellar magnitude any meteor would have if placed in the observer's zenith at a height of kilometers.

Definition of Aeronautic at

An object as in a wing or fuselage whose skin supports the load as opposed to an internal frame. Also sometimes called Spats or, when fully enclosing the wheel struts, Skirts. The latter spelling is a trademark of the Autogiro Corporation. The Kelvin and Rankine scales are absolute scales. Hovering at greater than one rotor diameter from the ground where re is no interaction between rotor downwash and the ground.
