Training - Understanding Handoffs and Coordination (Part 2)
by Jeff Clark

Handoffs and Coordination with Center:

Just like in real life, if a pilot is following his flight plan route, you do NOT need to do anything to coordinate a handoff with Center other than flash the plane on Center’s scope, and make sure that communications are switched prior to the plane entering Center’s airspace.

On the flip side, if the plane has been assigned a route in Center’s airspace which is NOT shown on the flight plan, you MUST tell Center about the new route prior to handoff, to give Center the opportunity to modify the
route if necessary. This works both ways – Center MUST tell you about any arrivals which are on a routing NOT shown on the flight plan before handing the plane off to you.

Additionally, you are not allowed to clear a plane through your airspace ceiling, so any plane that is going to go higher than 13,000 cannot be issued anything higher by SOCAL than 13,000. Center will continue the climb when he takes the handoff and has communications with the aircraft. Similarly, Center will tell all arrivals which would enter your airspace through the ceiling to stop their descent at 14,000, and it will be up to you to continue the descent when it is safe. These procedures ensure that if a controller becomes too busy, aircraft will not continue to enter the busy sector when the controller is too busy to handle them. A sample graphic is below. See current ZLA Policies for updated sector vertical and horizontal climbs and descents.

Aircraft which will enter your airspace laterally (coming in from outside your boundaries at an altitude lower than 14,000) will be flashed on your scope by Center well in advance of reaching the boundary. Accepting the handoff implies that the plane can continue on the published routing and enter your airspace. Center MUST ensure the airplane is on SOCAL’s frequency prior to the plane reaching the airspace boundary.
