    La primera, estoy haciendo ATPL test y me he encontrado con esto:

    A slow decompression may be caused by:
    1 a slight airtightness defect
    2 a bad functioning of the pressurization
    3 the loss of a window
    4 the loss of a door
    The combination of correct statements is:
    A) 1, 2
    B) 1, 2, 3, 4
    C) 1, 2, 3
    D) 3, 4

    A mi modo de ver, la respuesta correcta es la A, por tratarse de SLOW decompression, pero el corrector me marca como correcta la C. Ustedes dirán.

    Y la segunda pregunta es que no me acuerdo de como se hacia la corrección de minimos por temperatura.

    Gracias y buenos vuelos.

    Por lógica como bien dices la respuesta correcta es la A, una perdida de una ventana sin duda provocaría una descompresión explosiva.

    En cuanto a la segunda pregunta nose a que te refieres. de que minimos hablas?.

    Un saludo.

    Si miran esta página web, verán que pone que una ventana rota no provoca una despresurización explosiva sino una lenta, dice que el agujero tiene que ser del tamaño de una puerta. Yo no se hasta que punto es veraz esta información, pero lleva ya muchos años en internet.

    Es que la respuesta, The loss of a window, yo la interpreto como el desprendimiento de una ventana del avión, y a mi modo de ver, perder una puerta a perder una ventana, la compensación de presiones entre el interior y el exterior seria instantánea y por tanto de carácter explosivo.

    Con la segunda pregunta, me refiero a los mínimos de una ficha de aproximación, como corregir esa altura por temperatura.

    Gracias a los que van contestando.

    recognizes three distinct types of decompression events in aircraft:
    •Explosive decompression
    •Rapid decompression
    •Gradual decompression

    Explosive decompression

    Explosive decompression occurs at a rate faster than that at which air can escape from the lungs, typically in less than 0.1 to 0.5 seconds. The risk of lung trauma is very high, as is the danger from any unsecured objects which can become projectileProjectileA projectile is any object propelled through space by the exertion of a force which ceases after launch. Although a thrown baseball could be considered a projectile, the word more often refers to a weapon…

An explosion s a shock wave. If the shock wave is a supersonic detonation, then the source of the blast is called a «high explosive»…

    s have to pressure-breathe, whereby the lungs fill with air when relaxed, and effort has to be exerted to expel the air again.

    Paul Withey, an aviation expert, described an explosive decompression inside an aircraft cabin as similar to the explosion of a 500 pound (225 kilogram) bomb inside the cabin.

    Rapid decompression

    Rapid decompression typically takes more than 0.1 to 0.5 seconds, allowing the lungs to decompress faster than the cabin. The risk of lung damage is still present, but significantly reduced compared to explosive decompression.

    Slow decompression

    Slow, or gradual, decompression occurs slowly enough to go unnoticed and might only be detected by instruments. This type of decompression may also come about from a failure to pressurize as an aircraft climbs to altitude. This happened on a RyanairRyanair…

    Si falla una ventana la descompresión es lenta.
    Con una puerta incluso la de un carguero es rápida.
