The student pilot performed low pass flying four times over runway 27.
Since the wind direction was from 090 until 120 with velocity of 8 to 10 knots, the flight instructor advised the controller to change the runway in use to runway 09 and was approved. The flight instructor then instructed the student pilot to exercise a low pass on runway 09. The student pilot performed low pass three times over runway 09.
