Separation Standards
Definition
Minimum distances or time intervals required between aircraft to ensure safety. Vertical separation is typically 1,000 feet; horizontal separation varies by radar coverage and airspace type.

Wake Turbulence
Turbulent air generated by the wingtip vortices of a flying aircraft. Larger aircraft produce stronger wake turbulence, requiring following aircraft to maintain separation distance.
Radar Vectoring
The process of providing navigational guidance to aircraft by ATC through specific headings (vectors) based on radar observation. Used to sequence arriving aircraft and maintain separation.
Airspace Classification
The categorization of airspace into classes (A through G) based on the level of air traffic control service provided and the flight rules that apply. Class A is the most restrictive.
