1.
CAS = TAS (200)
TRACK (T) = 207
HEADING (T) = 200
DRIFT = 7 STARBOARD
G/S = 105/21*60 = 300
CRP-5
Set the middle dot on TAS (200)
Set true heading at the top (200)
Locate the ground speed arc and mark a dot 7 degrees starboard
Rotate the disk so that the dot is directly below the middle dot
Under true heading is the wind speed direction
And to find the speed count the boxes between the two dots
I may be wrong
