What heading should be turned to after being cleared from the Rusty departure from 18/22?

After being cleared from the Rusty departure from runways 18/22, the appropriate heading to turn to is 105°. This departure procedure is designed for pilots to maintain safe separation from terrain and surrounding airspace as they gain altitude after takeoff.

The chosen heading of 105° aligns with the established route that ensures aircraft adequately clear obstacles and follow the designated air traffic flow. In this case, a turn to 105° allows for a smooth transition into the en route phase of flight, facilitating communication and coordination with air traffic control regarding subsequent navigation and altitudes.

The other headings do not correspond with the specified departure route, as they may lead to potential conflicts with terrain, other air traffic, or deviations from the intended path that must be adhered to for safety and operational effectiveness. Thus, selecting 105° is integral to adhering to standard operating procedures and maintaining situational awareness in the departure phase.
