What actions are involved in "Emergency Gear Extension"?

The correct answer involves manually operating the gear handle and verifying the gear down indication, which is a critical step in the emergency gear extension procedure. When the primary gear extension mechanism fails, pilots must manually activate the gear handle to ensure that the landing gear is extended for landing safely.

This action is paramount because it not only involves physically moving the gear handle but also requires monitoring the landing gear indicators to confirm that the gear is fully deployed and locked. Verification of the gear down condition is essential, as landing with the gear retracted can lead to catastrophic outcomes.

The other options, while potentially relevant to overall flying safety or technique, do not represent the specific actions required in the emergency gear extension procedure. Adjusting flaps or managing speed may be part of a broader strategy for landing, but they do not directly address the immediate requirement to ensure the landing gear is properly extended and indicated as down. Maintaining straight flight until landing is generally good practice but again does not pertain specifically to the emergency gear extension process itself. Thus, option B is the focused and correct choice for this procedure.
