3. Sequencing and Spacing

One of the important jobs of a CTR controller is managing the sequencing and spacing of aircraft following the same route. Events bring heavy traffic and there will usually be MIT (Miles In Trail) restrictions on how closely aircraft are allowed to be spaced. Be attentive for the effects of pilots with different weather or aircraft types that may cause significantly different speeds while enroute. Use speed restrictions as needed to manage spacing between aircraft.

In addition to following MIT restrictions, be aware and don't let your neighbors get overwhelmed. Use vectors or holds as needed to increase spacing. Note that an aircraft at high altitudes will often have a much larger turn radius than at lower altitudes and speeds.

See the VATUSA Master Class on Sequencing and Spacing for examples of how to manage traffic in this environment.
