When I was a "Runway Controller" [ATCA11] at Manch, I was instructed to do
FOUR runs on the Active Runway...Up and Down to the Left/Right of the centreline and same again to the opposite side. Two mile runway x 4 equals eight miles. At the posted "Airside speed limit of 15MPH" I think is "about" the 20 min mark. that does not include stopping/circling to look at "suspicious" objects...dark stains, etc
I also did the Taxyways and aprons...
