Frage
1) ¿What is the “90 seconds rule”?
Antworten
-
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.

Frage 2
Frage
2) Which is the main difference between monocoque and semi-monocoque structures?
Antworten
-
Structural elements to share the load
-
Semi-Monocoque is used in missiles
-
Monocoque is only for wings
-
Semi-monocoque is only for fuselage
Frage 3
Frage
3) Why are cockpit windows made with a thin-film gold?
Antworten
-
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

Frage
4) What is the wing stringers?
Antworten
-
They are span-wise elements to support the skin and increase the rigidity to compression.
-
They are attached to formers in the wing.
-
They are support the main loads of the wing performance.
-
They are used only in military aircraft

Frage 6
Frage
6) The ribs of the wind are orientated....
Antworten
-
In the same direction as the aerodynamic chord
-
Perpendicular to the aerodynamic chord
-
Oblique to the aerodynamic chord
-
Ribs are not located in the wing but in the fuselage.
Frage 7
Frage
7) What is the Skin of the aircraft structure?
Antworten
-
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.
Frage 8
Frage
1) Low-wing characteristic:
Antworten
-
Block pilot’s visibility in a turn
-
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

Frage 13
Frage
6) C-anard disadvantage:
Antworten
-
Reduced forward and down visibility
-
Higher landing and take off speeds
-
Lower maneuverability

May be prone to suffering a dangerous deep stall condition
Frage 14
Frage
7) Which is the main advantage of mid-wings?
Antworten
-
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
