REVIEW BASIC NAVIGATION

To navigate by referring to the moon is one of the method of:

• Pilotage navigation;

• Celestial navigation

• Dead reckoning navigation

• Radio navigation

A method of navigation solely by the aid of visible landmark is

• Pilotage navigation

• Celestial navigation

• Dead reckoning navigation

• Radio navigation

Type of navigation, except

• Pilotage navigation

• Celestial navigation

• Objective navigation

• Radio navigation

Earth, also known as

• Beta

• Terra

• Delta

• Gamma

The angle of parallel of latitude is

• 0⁰ – 90⁰ N & S

• 0⁰ – 90⁰ E & W

• 000⁰ – 180⁰ N & S

• a. 000⁰ – 180⁰ E & W.

Isogonic line is

• Line drawn on maps connecting positions that have zero magnetic variation

• Line drawn on maps connecting positions that have the same magnetic variation

• Line drawn on maps that cuts the meridian of longitudes with the same angle

• Line drawn on maps which join places of equal elevation (equal vertical distance above or below mean sea level)

Agonic line is

• Line drawn on maps connecting positions that have zero magnetic variation

• Line drawn on maps connecting positions that have the same magnetic variation

• Line drawn on maps that cuts the meridian of longitudes with the same angle

• Line drawn on maps which join places of equal elevation (equal vertical distance above or below mean sea level).

This scale “One cm equal to 10nm” known as

• Graduated scale

• Statement in word scale

• Representative fraction scale

• Aviation scale

If 1 cm on the map = 10 km on the earth, means the map have a scale of

• 1 : 10.000

• 1 : 100.000

• 1 : 1.000.000

• 1 : 10.000.000

The map have scale “1 : 500.000”, distance point “A” to point “B” in map is 5 cm. distance point “A” to point “B” actually:

• 25 Km

• 2.500 M

• 1 Km

• 100 M
