  1. 11. The reason to produce cilindric fuselage is:
    1. A-more space to store the load or passengers
    2. B-construction is easier compared with a squared fuselage
    3. C-to improve the distribution of the pressure due to the fuselage pressurization
    4. D-to produce a third (1/3) of the total aircraft’s lift
  2. 22. Cylindrical fuselages use less material than the squared fuselages because:
    1. A-the sphere has, for a given volume, less surface than a cube
    2. B-the sphere has, for a given volume, more surface than a cube
    3. C-the sphere has, for a given perimeter, less surface than a cube
    4. D-the sphere has, for a given surface, more perimeter than a cube
  3. 33. The angle of decrease of the back of a fuselage depends on:
    1. A-the load that is going to be transported
    2. B-the aircraft’s stall speed
    3. C-the boundary layer separation
    4. D-the passengers windows' position
  4. 44. Regarding double lobe fuselage:
    1. A-normally both the upper area and the lower are pressurized with the same pressurization system
    2. B-normally the upper area is pressurized with a different system than the lower area
    3. C-normally the upper area is the only area pressurized
    4. D-formers are not used
  5. 55. In order to transport big loads, the best option is:
    1. A-squared fuselage to use less material
    2. B-squared fuselage
    3. C-double lobe fuselage
    4. D-mid-wing structure
  6. 66. Regarding combat aircraft ́s fuselage:
    1. A-is conditioned by the fuel tank and the engine
    2. B-is a monocoque structure similar to boats structure
    3. C-it holds the missiles because all the fuel is hold inside the wings
    4. D-normally is a frame construction so as to fly transonic
  7. 77. Regarding semi-monocoque structures:
    1. A-longerons are used to avoid bending (pandeo) produced by big angles of attack
    2. B-vertical stabilizer are ensambled to the skin of the aircraft using screws
    3. C-longerons provide rigidity against flexion
    4. D-the skin is very thick so it is not used in aviation
  8. 88. Passenger cabin windows:
    1. A-are places where there is an acumulation of pressure
    2. B-filter air outside the aircraft
    3. C-are favorable to the structure design but not to aircraft aerodynamics
    4. D-are favorable to aircraft aerodynamics but not to the structure design
  9. 91. In commercial airplanes, how many sheets does each passenger ́s window have?
    1. Aa. Only a thin one, to be as light as possible.
    2. BTwo, separated by an air gap, and usually a third separated layer that is closest to the passenger that does not take any pressure load.
    3. CAt least two sheets together, to make sure the window is resistant enough against possible impacts.
    4. Dd. One laminated thick window to comply with all impact requirements.
  10. 10Which is the 90 sec rule?
    1. AAll the passengers must leave the aircraft using any of the doors of the plane
      in 90 seconds.
    2. BHalf of the passengers must leave the aircraft using any of the doors of the
      plane in 90 seconds.
    3. CAll the passengers must leave the aircraft using only the 50 % of the doors of the plane in 90 seconds.
    4. DThe crew of the airplane must be capable of opening all the doors in 90 seconds.
