How is the CRJ autopilot engaged?

The autopilot in the CRJ is engaged by selecting the autopilot switch after reaching a stable flight condition. This procedure ensures that the aircraft is in a safe and controlled environment before allowing the autopilot to manage the flying tasks. Engaging the autopilot at a stable flight condition, such as stable altitude and airspeed, minimizes the risk of abrupt control inputs or changes that could affect the aircraft's performance or safety.

The selection of the autopilot switch is typically located on the control panel, and pilots are trained to use this step methodically in conjunction with other flight parameters. Engaging the autopilot under improper conditions might lead to undesired flight characteristics, which is why stability is a prerequisite in this process.

The other choices do not represent the correct method of engaging the autopilot as they either involve actions not directly related to the autopilot system or are unrelated to the process.
