/pˈrɛʃər ˈæltɪtjuːd/

Meaning and Usage

Pressure altitude refers to the altitude in the International Standard Atmosphere (ISA) at which the atmospheric pressure is equal to a specific value, usually measured in inches of mercury (inHg) or millibars (mb). This concept is primarily used in aviation and meteorology for aircraft performance calculations, as it helps pilots understand the aircraft's performance characteristics based on the current atmospheric conditions. The term is commonly employed in both spoken and written forms, especially in technical or aviation-related contexts.

Frequency of Use

Pressure altitude is frequently used in specialized fields such as aviation, meteorology, and engineering. While it may not be a term encountered in everyday conversation, it is essential for professionals in air traffic control, piloting, and atmospheric research.

Example Sentences

1. The pilot was instructed to adjust the aircraft's altitude based on the current pressure altitude.

2. Перевод: Пилот получил указание изменить высоту самолета в зависимости от текущей высоты по давлению.

3. Understanding pressure altitude is crucial for maintaining optimal flight performance.

4. Перевод: Понимание высоты по давлению жизненно важно для поддержания оптимальной производительности полета.

5. The meteorologist explained how changes in atmospheric pressure affect pressure altitude readings.

6. Перевод: Метеоролог объяснил, как изменения атмосферного давления влияют на показания высоты по давлению.

Idiomatic Expressions

While pressure altitude itself is not commonly associated with idiomatic expressions, it can appear in several contexts related to aviation and pressure concepts. Here are some related idiomatic expressions that involve the term "pressure":

1. Under pressure: Feeling stressed or pressured due to circumstances.
2. The airline operations center was under pressure to get planes off the ground safely.

3. Перевод: Оперативный центр авиакомпании испытывал давление, чтобы безопасно отправить самолеты в воздух.

4. Pressure cooker: A situation or environment that is characterized by intense stress or anxiety.

5. The chaotic airport was a pressure cooker during the holiday rush.

6. Перевод: Пора года с большим количеством пассажиров в аэропорту была накаленной обстановкой.

7. High pressure: Referring to intense situations or systems that can lead to increased performance or productivity.

8. Working in high-pressure environments is common for air traffic controllers.
9. Перевод: Работать в условиях высокого давления — обычное дело для диспетчеров воздушного движения.

Etymology

The term pressure comes from the Latin word pressura, meaning "a pressing" or "a weight." The word altitude originates from the Latin altitudo, meaning "height" or "elevation." Thus, pressure altitude combines both terms to describe the height related to atmospheric pressure.

Synonyms and Antonyms

Synonyms - Indicated Altitude - Density Altitude (in specific contexts)

Antonyms - Absolute Altitude (which refers to the actual height above sea level) - Ground Level (when considering the base reference point)
