Flag Display Guide. Displaying the Flag at Half Mast: When you need to display the American flag at half mast, you actually need to hoist it completely to the peak of the pole and then instantly lower it to the half staff position. At the close of the day, the flag should again be raised to the peak of the flag pole and then lowered completely.
When we properly display this powerful symbol, we signal our respect for everything it represents. 1  The flag shouldnât be flown in inclement weather unless itâs an all-weather flag. 2  Flags displayed at night should be properly illuminated. 3  In a time of national mourning, hang the flag at half-mast.
