Under what condition can deviations from procedures established in the Aero ARTCC and Jackson ATCT LOA be made?

The correct answer is that deviations from the procedures established in the Aero ARTCC and Jackson ATCT LOA can only occur after coordination. This means that any deviation from established procedures requires prior discussion and agreement among the involved air traffic control units. Coordination is essential to maintain safety, ensure effective management of air traffic, and prevent miscommunication between ATC facilities.

The necessity for coordination helps ensure that all affected parties are aware of changes that might impact air traffic management, thereby minimizing the risk of conflicts or safety incidents. Coordination allows for the assessment of potential effects on air traffic flow and the implementation of any necessary adjustments.

Options suggesting that deviations can happen without prior coordination or by simply consulting nearby units do not adequately address the importance of communication and mutual agreement required for safety in air traffic operations. Additionally, issuing a new clearance does not inherently grant the authority to deviate from established procedures without prior coordination.
