To open the GSD on the CRJ 550, you must turn the operating handle in which direction?

To open the GSD (Galley Service Door) on the CRJ 550, you need to turn the operating handle counterclockwise. This is a standard procedure for gaining access to the galley area, which is essential for loading and unloading supplies or conducting maintenance tasks.

Turning the handle counterclockwise engages the mechanism that releases the door from its locked position, allowing it to swing open. Familiarity with this function is crucial for ground crew and personnel who need to ensure efficient service and safety during pre-flight and post-flight operations.

Understanding the operation of door mechanisms, especially in aircraft like the CRJ 550, is vital for ground handling and maintenance procedures, as it directly impacts the workflow related to passenger service and aircraft readiness.
