Browser air traffic control: keep arrivals and departures apart.

OUR TAKE Quietly the hardest thing on this list. Read the tutorial.
Open vector-tango.com and take the control scope.
Vector aircraft — heading and altitude — to keep separation between arrivals and departures.
Land and launch without a collision; the shift ends when the traffic does.
Give one instruction at a time. A simultaneous turn and descent is how separation breaks.
Hold traffic in a stack rather than circling it near the runway.
Land into the wind; the usable runway changes with the weather.
