Aircraft maintenance guidelines:
Aircraft noise pollution is a serious consideration at MCAS Iwakuni because of the densely populated areas immediately adjacent to the airfield. Particularly sensitive to our Japanese Hosts are Tactical Jet engine turnups after normal working hours and during holidays.

  1. IDLE POWER TURN-UPS ANYTIME EXCEPT DURING QUIET HOURS.
