Pressure altitude

+ Save concept

Pressure altitude within the atmosphere is the altitude in the International Standard Atmosphere (ISA) with the same atmospheric pressure as that of the part of the atmosphere in question. [1]

Altimeter

An altimeter or an altitude meter is an instrument used to measure the altitude of an object above a fixed level.

Atmosphere

An atmosphere is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body.

Atmospheric pressure

Atmospheric pressure, sometimes also called barometric pressure, is the pressure within the atmosphere of Earth (or that of another planet).

Aviation

Aviation, or air transport, refers to the activities surrounding mechanical flight and the aircraft industry.

Aviation transponder interrogation modes

The aviation transponder interrogation modes are the standard formats of pulsed sequences from an interrogating Secondary Surveillance Radar (SSR) or similar Automatic Dependent Surveillance-Broadcast (ADS-B) system.

Bar (unit)

The bar is a metric unit of pressure, but is not approved as part of the International System of Units (SI).

Barometric formula

The barometric formula, sometimes called the exponential atmosphere or isothermal atmosphere, is a formula used to model how the pressure (or density) of the air changes with altitude.

Commercial pilot license

A commercial pilot license (CPL), is a type of pilot licence that permits the holder to act as a pilot of an aircraft and be paid for his/her work.

Density altitude

The density altitude is the altitude relative to standard atmospheric conditions at which the air density would be equal to the indicated air density at the place of observation.

Flight level

In aviation and aviation meteorology, a flight level (FL) is defined as a vertical altitude at standard pressure, nominally expressed in hundreds of feet.

Foot (unit)

The foot (feet; abbreviation: ft; symbol: ′, the prime symbol) is a unit of length in the imperial and US customary systems of measurement.

Inch of mercury

Inch of mercury (inHg and ″Hg) is a unit of measurement for pressure.

International Standard Atmosphere

The International Standard Atmosphere (ISA) is an atmospheric model of how the pressure, temperature, density, and viscosity of the Earth's atmosphere change over a wide range of altitudes or elevations.

National Oceanic and Atmospheric Administration

The National Oceanic and Atmospheric Administration (NOAA; pronounced, like "Noah") is an American scientific agency within the United States Department of Commerce that focuses on the conditions of the oceans, major waterways, and the atmosphere.

Pascal (unit)

The pascal (symbol: Pa) is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength.

Paul Kollsman

Paul Kollsman (February 22, 1900 in Germany – September 26, 1982 in Beverly Hills, California) was a German-American inventor.

Private pilot licence

A private pilot licence (PPL) or, in the United States, a private pilot certificate, is a type of pilot licence that allows the holder to act as pilot in command of an aircraft privately (not for remuneration).

QNH

QNH is a Q code indicating the atmospheric pressure adjusted to mean sea level.

New!!: Pressure altitude and QNH · See more »

Sea level

Mean sea level (MSL) (often shortened to sea level) is an average level of the surface of one or more of Earth's oceans from which heights such as elevations may be measured.

New!!: Pressure altitude and Sea level · See more »

Standard conditions for temperature and pressure

Standard conditions for temperature and pressure are standard sets of conditions for experimental measurements to be established to allow comparisons to be made between different sets of data.
