 # PPL test – 6/10 Navigation | Explanations

#### 1) True heading is 270°. Magnetic Variation is 10° East. What is magnetic heading?

• 260° (correct answer)
• 270°
• 280°
• Cannot be calculated

#### Explanation:

See explanation on Wikipedia

#### 2) An aeroplane is on VOR radial 124, and it is flying at magnetic heading 300°. OBS setting is 300°. What does CDI indicate?

• TO/FROM flag is positioned: FROM, the needle moves one dot to the left.
• TO/FROM flag is positioned: TO, the needle moves one dot to the right.
• TO/FROM flag is positioned: FROM, the needle moves two dots to the left.
• TO/FROM flag is positioned: TO, the needle moves two dots to the right. (correct answer)

Explanation:

124°+180°= 304°;One dot 2° on the CDI 304°-300°= 4°;4°/2°= 2 dots

• 2.45 NM.
• 3.35 NM.
• 4.08 NM. (correct answer)

Explanation:

#### 5) Magnetic course is calculated using the equation

• true course plus/minus compass deviation.
• true course plus/minus magnetic variation. (correct answer)
• true heading plus/minus magnetic variation.
• magnetic heading plus/minus compass deviation.
