Drift
Drift angle is how many degrees the heading is to the right or left of the track.

Following variables must be known in order to find the W/V: HDG, Drift, GS, and TAS.
If drift is not directly given in the question, we can compare our HDG with the TRK to obtain the drift.

1. Heading (HDG): The heading is given in the question = 005°(T)

2. Drift: The drift is given in the question = 5° left

3. Groundspeed (GS): The GS is given in the question = 108 kt

4. True Airspeed (TAS):
Since there is a headwind component, the groundspeed will be less than the true airspeed. Therefore,

• TAS = GS + headwind component
• TAS = 108 kt + 10 kt
• TAS = 118 kt

CALCULATE THE W/V
Now that we have all four variables, we can use a flight computer (CRP-5) to calculate the W/V using the following steps:
Steps 1 & 2 (Figure 1)

1. Set the center to your TAS of 118 kt.
2. Bring HDG of 005° under “TRUE HEADING”.

Steps 3 - 6 (Figure 2)

3. Mark a dot 5° to the left of the centerline, at the point where the GS of 108 kt intersects.
4. Rotate the disk and align the dot under the TAS on the centerline.
5. Read the wind speed of 14 kt by comparing the speed at the dot with the TAS (center).
6. Read the wind direction of 047° under “TRUE HEADING”.

Therefore, the answer is: W/V = 047°/14 kt
