DME Hold Entries RNAV

An unusual question for Radio Navigation, as holds and hold entries are covered in Air Law.

Sector one is a parallel join and sector three is a direct join. These are the only two possible as you are flying either directly along or back along the hold track when the DMEDME —Distance Measuring Equipment arc is completed.

Sector two, an offset join, cannot be achieved in this fashion.

If you have not studied these sector joins yet, do not worry. The answer is sectors 1 and 3, and that answer only.
