Examen Diagnóstico para Nuevos Alumnos 3

✅ PRODUCES CERTAIN INCREASES IN VELOCITY WITH CORRESPONDING REDUCTION IN TEMPERATURE.

Airflow over an aerodynamic surface accelerates as it moves around the shape of the surface. When the airflow velocity increases, the static pressure and temperature decrease. This principle is important in understanding how air behaves over wings, airfoils, ducts, and other aerodynamic surfaces.

✅ TOMAR NOTA DE CUALQUIER EVIDENCIA DE FILTRACIONES.

Antes de limpiar una aeronave o parte de ella para una inspección, se debe observar y registrar cualquier evidencia de filtraciones de combustible, aceite, fluido hidráulico u otros líquidos.

Esto es importante porque la limpieza puede eliminar rastros útiles para detectar el origen de una falla o condición anormal.

✅ LIST OF CAPABILITY.

The Certificate of Approval of a DAN 145 CMA must always be accompanied by its List of Capability. This document defines the aircraft, components, or specialized work that the CMA is authorized to maintain.

It is essential because the certificate alone does not show the full approved maintenance scope.

✅ AIR.

In every type of aircraft powerplant, except the rocket, the principal fluid used for propulsion is air. Engines accelerate or use airflow to produce thrust or power. A rocket is different because it carries its own oxidizer and does not depend on atmospheric air.

✅ IN ALL TYPES OF MATERIALS.

Ultrasonic inspection equipment can detect defects in many kinds of materials, including metals, composites, plastics, and ceramics 🔊. It works by sending high-frequency sound waves through the material and analyzing the reflected signals to find internal flaws, cracks, voids, or separations.

✅ LAS RELACIONES Y EL TIEMPO.

En Stoner, Freeman y Gilbert, las funciones de planificación, organización, dirección y control no se entienden como actos aislados, sino como actividades que dependen continuamente de las relaciones entre personas y del tiempo en que se desarrollan. Son elementos intangibles porque no se pueden medir como un recurso físico, pero resultan esenciales para coordinar acciones, tomar decisiones y alcanzar metas dentro de la organización.

✅ THE SPEED OF SOUND.

In the study of high-speed airflow, the speed of sound is very important. As airflow approaches this speed, compressibility effects, pressure changes, and shock waves become significant. This is why high-speed aerodynamics is closely related to Mach number.

✅ LA SALUD, LAS PREOCUPACIONES Y EL ESTADO ANÍMICO.

La pregunta apunta a los factores humanos personales que afectan el rendimiento del técnico. En este contexto, la performance no depende de un solo elemento, sino de una combinación de condiciones del propio individuo. Por eso, la alternativa más completa y fiel al enfoque del texto es la que reúne salud, preocupaciones y estado anímico, ya que todos esos aspectos pueden alterar la atención, el juicio y la ejecución de tareas.

✅ ELECTRICAL HEATING ELEMENTS.

Many pitot-static tubes are equipped with electrical heating elements to prevent ice formation during flight. This is important because ice can block the pitot or static openings, causing incorrect readings on instruments such as the airspeed indicator, altimeter, and vertical speed indicator.

✅ RAPIDLY CORRODE ALUMINUM ALLOY AND OTHER METAL.

Some fire extinguishing agents can rapidly corrode aluminum alloys and other metals if they are not removed after use. For that reason, after extinguishing a fire, the affected area must be cleaned and inspected carefully to prevent structural or component damage.
