5 free sample questions of the 67 in this topic. The full set is in the app.

1. Question 1

   Variation in navigation is:

   • A.The difference between true heading and magnetic heading (caused by the geomagnetic field)
   • B.The difference between magnetic and compass heading
   • C.Wind correction
   • D.Clock error
   Show answer & explanation

   Answer: A. The difference between true heading and magnetic heading (caused by the geomagnetic field)

   Variation: angular difference between true north and magnetic north. Deviation: difference between magnetic and compass (caused by the airplane itself).

2. Question 2

   How is east variation applied to a true heading to get magnetic heading?

   • A.Add it
   • B.Subtract it — 'East is least'
   • C.Halve it
   • D.Ignore it
   Show answer & explanation

   Answer: B. Subtract it — 'East is least'

   East variation is subtracted from true, west is added. Mnemonic: East is least, West is best.

3. Question 3

   An airplane has a true course of 090°. Winds are from 060° at 20 kt. TAS is 120 kt. The required wind correction angle is:

   • A.Into the wind — to the left (a left crab of several degrees)
   • B.To the right
   • C.Zero
   • D.Downwind
   Show answer & explanation

   Answer: A. Into the wind — to the left (a left crab of several degrees)

   Wind from the left-front requires a left crab to stay on course. (Exact number via E6B.)

4. Question 4

   A cruise ground-speed check shows you are 5 minutes behind flight plan across a 30-NM leg. Your corrective action is:

   • A.Climb
   • B.Recompute ETA/fuel; consider speed adjustment and fuel reserve
   • C.Ignore
   • D.Turn 20° right
   Show answer & explanation

   Answer: B. Recompute ETA/fuel; consider speed adjustment and fuel reserve

   Revise ETA, ground speed, fuel consumption, and alternate options using the updated ground speed.

5. Question 5

   Magnetic compass — during an accelerating level flight on an east or west heading:

   • A.Compass reads a turn toward North
   • B.Compass reads a turn toward South
   • C.No error
   • D.Reads exact heading
   Show answer & explanation

   Answer: A. Compass reads a turn toward North

   ANDS: Accelerate → North error; Decelerate → South error. On east/west headings only.
