Can the extension handle be used for retraction after practice emergency gear extension?

The correct choice indicates that the extension handle can be utilized for retraction only if hydraulic actuation has been de-selected. This means that in the event of an emergency gear extension practice, the system operates differently than it would under normal circumstances.

When hydraulic actuation is de-selected, it typically allows for manual operation to control the gear system, which includes the retraction process. This is crucial in emergency situations where hydraulic systems may not function properly, requiring manual intervention to safely manage the landing gear. Using the extension handle in this state ensures that the gear can be safely retracted without risking hydraulic interference.

In contrast, if the hydraulic actuation remains active while attempting to use the extension handle, it could create conflicts within the system. Therefore, knowing when to activate or deactivate the hydraulic functions is essential for safe operation. Understanding these operational protocols is vital for effective emergency gear management.
