What is the required wake turbulence separation for N18NC, a LJ35, departing Runway 28R?

The correct answer indicates that a wake turbulence separation of 3 minutes from N18NC's rotation is required for a Light Jet aircraft (like the LJ35) departing from Runway 28R. This is in line with established wake turbulence separation standards, which account for the size and weight of the aircraft as well as the potential for turbulence generated by its departure.

When an aircraft rotates and takes off, it generates wake turbulence that can affect trailing aircraft. The recommendation of 3 minutes is significant because it allows enough time for the turbulence to dissipate before another aircraft operates in the same airspace behind it. This separation time is especially crucial when larger categories of aircraft are involved, as their wake vortices can be powerful and potentially hazardous to smaller aircraft that may be taking off or landing subsequently.

Understanding wake turbulence is essential for ensuring safe operations at airports, particularly where numerous departures and arrivals occur. In this context, the 3-minute separation helps ensure the safety of subsequent aircraft and aligns with aviation safety standards.
