Refer to figure.
Which answer assigns the correct names to the projection types shown in the annex?

  • A

    (A) direct, (B) oblique, (C) transversal

  • B

    (A) cylindrical, (B) conical, (C) azimuthal

  • C

    (A) azimuthal, (B) conical, (C) oblique

  • D

    (A) transversal, (B) azimuthal, (C) conical

This question asks only for the names assigned to different projection types. There are three main projection types used to create the three major forms of aeronautical charts:

Azimuthal/Planar - Used to produce Polar Stereographic Charts
Cylindrical -
Used to produce Direct/Indirect Mercator Charts
Conical - Used to produce Lambert Conformal Charts

Each type is named after what shape part of the Earth is projected onto

In azimuthal/planar projection, a light source projects part of the Earth onto a planar surface. We see a planar surface in Image C, making (C) azimuthal a correct option.

Cylindrical projection projects an image of the Earth onto a cylinder wrapped around it, as in image A - so (A) cylindrical is correct.

Conical projections project part of the Earth onto a cone shape, making (B) conical another correct option.


Note: Even if you are unsure of the word "azimuthal", by simply comparing the shapes to the answer options you could arrive at (A) cyclindrical (B) conical ...
There is only one answer that fits this possibility
