What is the answer to this question about aircraft position based on an NDB? An aircraft is intending to track from NDB ‘A’ to NDB ‘B’ on a track
  of 050° (T), heading 060° (T). If the RBI shows the relative bearing
  of ‘A’ to be 180° and the relative bearing of ‘B’ to be 330° then the
  aircraft is:
  
  
  A. Port of track and nearer ‘A’
  B. Port of track and nearer ‘B’
  C. Starboard of track and nearer ‘A’
  D. Starboard of track and nearer ‘B’
Yes, "D" is correct. A picture is worth a thousand words......
