When we plan for a 255º(T) heading and a track of 252º(T), the expected drift due to forecasted winds is 3º left.

Since we are drifting 3º left in flight, the winds are close to what was forecast, and we will track 252º(T) as expected. The track error angle is therefore 0º.

Note: There are a few different variations of this question so be careful in the exam, and draw a little picture if necessary (remember that drift is from heading to track).
