JAA ATP - GNAV - Dead Reckoning
I noticed that using the CR-3/5 for solving the following type of questions (wind triangles - Dead Reckoning) is not really that accurate, since the given answers are somewhat close together. What's the best way to find the correct answer?
Example:
TAS = 170 kt
HDG (T) = 100°
W/V = 350/30 kt
Track (T) and GS?
1. 109 - 182 kt (correct answer)
2. 110 - 180 k
3. 103 - 178 kt
4. 091 - 183 kt
Thank you!
