Human Factors
I was in the right seat at BMQ with my student; a 60-hour student pilot nearing his checkride; in the left. We were holding short of Runway 19 and as he ran a before takeoff check for a short field takeoff; I cleared final for traffic. No one was announcing their intentions to land and no one was in the pattern; and I couldn't see anyone on final; so we taxied into position on the end of the runway to perform a short-field takeoff. The procedure calls for holding the brakes while lined up on the runway; so I instructed the student to point down the runway and apply brakes as I talked through the procedure once more; per his request. As I reiterated the short field procedure; I saw a King Air perform a go around on Runway 19 to our right. He did not make a go around call and my student attempted to raise the aircraft on the radio to apologize; but was not being acknowledged by the King Air. After the King Air was a safe distance upwind; we departed and returned to [home base] where we debriefed the risk of turning our backs to final. [At] uncontrolled airports; where radio communications aren't necessary; [it] becomes essential to avoid situations like that; especially when aircraft are painted the same color as the sky. The aircraft on final probably didn't see us because we were painted white; we were lined up on the numbers; and blended in with the runway. I learned not to try and teach while my back is turned to final.
