Description should include the following:

- Air traffic control (ATC) is responsible for ensuring that the necessary coordination has been accomplished before allowing an aircraft under their control to enter another controller’s area of jurisdiction.
- Before issuing control instructions directly or relaying through another source to an aircraft that is within another controller’s area of jurisdiction that will change that aircraft’s heading, route, speed, or altitude, ATC ensures that coordination has been accomplished with each of the controllers listed below whose area of jurisdiction is affected by those instructions, unless otherwise specified by a letter of agreement or a facility directive:
  - The controller within whose area of jurisdiction the control instructions are issued
  - The controller receiving the transfer of control
  - Any intervening controller(s) through whose area of jurisdiction the aircraft will pass
