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

3) The Co-ordinated Universal Time (UTC) is

  • the Local Time.
  • the Zone Time.
  • the time on the longitude 0 degrees. (correct answer)

4) How far will an aircraft travel in 2-1/2 minutes with a groundspeed of 98 knots?

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

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.
