What is an example of a heading given to depart a fix?

The choice of "American Two, depart Ames heading zero seven zero, when able proceed direct Columbus" is a clear example of a heading given to depart a fix because it explicitly states a direction (zero seven zero) for the aircraft to follow after departing the specified fix, Ames. This aligns with standard air traffic control practices, where pilots are given a specific heading to follow after leaving a waypoint or fix.

This guidance is crucial for ensuring the safe and orderly flow of air traffic, as it provides the pilot with a clear path to follow while also allowing for the possibility of navigating directly to a subsequent waypoint (Columbus). The phrase "when able" indicates that the pilot should proceed direct to Columbus as soon as it is safe and feasible to do so, which emphasizes the need for situational awareness and adherence to airspace structure.

The other options do not provide a specific departure heading from a fix. For example, the first choice gives a heading but does not specify a departing fix. The third option focuses on a direct route to the next waypoint without mentioning a heading initially. The last option instructs the aircraft to maintain its current heading instead of departing on a new one. Each of these examples fails to meet the criteria of providing a clear departure heading
