Simultaneous takeoffs between aircraft departing in the same direction from parallel runways/helicopter takeoff courses can be authorized if the centerlines/takeoff courses are separated by at least 200 feet and the courses diverge by 15 degrees or more immediately after departure.
Step-by-step explanation:
In aviation, simultaneous takeoffs between aircraft departing in the same direction from parallel runways/helicopter takeoff courses can be authorized if the centerlines/takeoff courses are separated by at least 200 feet and the courses diverge by 15 degrees or more immediately after departure.
