How much lateral spacing must exist between numbers 1 and 2 in a wing takeoff?

In a wing takeoff, the recommended lateral spacing between number 1 and number 2 aircraft is 20 feet. This spacing is crucial for maintaining safe separation during the takeoff roll and ensuring that the aircraft do not interfere with each other’s operations. The 20-foot distance helps to minimize the risk of wake turbulence and allows for adequate maneuverability, particularly if either aircraft needs to alter its trajectory slightly during takeoff. This standard spacing is often established in training and operational procedures to enhance safety for all aircraft involved in the maneuver.

The other options suggest distances that do not meet the established safety standards for wing takeoffs, potentially leading to increased risk during this critical phase of flight.
