Environment - Non Weather Related; Human Factors; Procedure
C182/U was traveling eastbound at 5;500 FT and 10 miles west of GBN VOR in contact with Luke Approach Control. Visibility clear below 12;000 FT 20 miles. Visually scanning; Luke called traffic 1-2 o'clock at 5;700 FT descending. Traffic appeared to be a light twin. Immediately initiated a right turn to descend and avoid. Not sure of distance but appeared to be less than a half SM. Luke said traffic was not in contact with them but they tracked him until he landed. The other pilot later called me and we discussed [the event]. There are many aircraft in the area training and the other pilot advised me to monitor 128.925 - seems training traffic should also monitor Luke Approach for safety. I; as an instructor; always advise students to use ATC.
A VFR C182 pilot in contact with Luke Approach was advised of traffic descending and as the near missed was recognized he took evasive action from a VFR light twin returning from the training area.
