Frage 1

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.
  • 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.

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

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 5

Frage
5) Stringers are used in the wing to fix...
Antworten
  • buckling effect
  • Coanda effect
  • Traction forces
  • Torsion forces

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 9

Frage
2) If engines are located “faired” in the wing , the structural design of the joint region is highly complex.
Antworten
  • True
  • False

Frage 10

Frage
3) What is used in fighters.
Antworten
  • Central Box.
  • Formerons

Frage 11

Frage
4) Cruciform tail exposes the lower part of the rudder to undisturbed air during high angle-of-attack conditions and spins.
Antworten
  • True
  • False

Frage 12

Frage
5) Twin tail characteristics: 1) High maniobrability. 2) Reduces the weight. 3) Is proposed to reduce adverse roll-yaw coupling. 4) Fits into existing hangars.
Antworten
  • 1,3
  • 1,2
  • 1,2,4
  • 2,3,4

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
