1) ¿What is the “90 seconds rule”?

Selecciona una de las siguientes respuestas posibles:

  • Every comercial aircraft must be able to be evacuated, in medium density configuration,within 90 seconds, using only 50% of the doors. In order to measure the time, the passengers are a representative sample of population without any preparation.

  • Every comercial aircraft must be able to be evacuated, in maximum density configuration,within 90 seconds, using only 50% of the doors. In order to measure the time, the passengers are a representative sample of population without any preparation.

  • Every comercial aircraft must be able to be evacuated, in medium density configuration, in more than 90 seconds, using only 75% of the doors. In order to measure the time, the passengers are a representative sample of population without any preparation.

2) Which is the main difference between monocoque and semi-monocoque structures?

Selecciona una de las siguientes respuestas posibles:

  • Structural elements to share the load

  • Semi-Monocoque is used in missiles

  • Monocoque is only for wings

  • Semi-monocoque is only for fuselage

3) Why are cockpit windows made with a thin-film gold?

Selecciona una de las siguientes respuestas posibles:

  • Because it is stylish

  • In order to increase the windows resistance

  • thin-film gold is needed for the airplane’s anti-fog system

  • It reduces the radar signature

7) What is the Skin of the aircraft structure?

Selecciona una de las siguientes respuestas posibles:

  • It is the external part of the structure, which mission is to resist shear and isolate the fuel from the atmosphere.

  • It is a lift device attached to the fuselage

  • It is the internal part of the structure, which mission is to resist shear and isolate the fuel from the atmosphere.

  • It is the external part of the window, which mission is to resist shear and avoid hits on the window surface.

  • Wing can be manufactured in only 1 section

  • The center wing structure is used for the cabin flood and to accommodate the landing gear without aerodynamic penalty

  • Structural carrythrough

7) Which is the main advantage of mid-wings?

Selecciona una de las siguientes respuestas posibles:

  • Aerobatic maneuverability

  • Prevent "floating" (ground effect) that complicates the landing and the placement of motors allow landing in unimproved fields

  • Delay the critical Mach

  • The center wing structure is used for the cabin floor and to accommodate the landing gear without aerodynamic penalti
