Is the alternate gear extension control located in both cockpits?

Is the alternate gear extension control located in both cockpits?

• A. True
• B. False
• C. Only in the rear cockpit
• D. Not used in either cockpit

Answer: (B)

The key idea is how redundancy is implemented for cockpit controls. Not every critical system control is duplicated in a two-seat aircraft; some backups are provided through a single, dedicated control in one cockpit to keep the procedure clear and prevent conflicting inputs. For the alternate gear extension, there is one backup control that allows extending the landing gear if the primary hydraulic system fails. It is not mirrored in both cockpits, so the statement that it’s located in both is not correct. Having one control avoids the possibility of both pilots moving a separate handle and giving conflicting commands during an emergency, which keeps the procedure simple and unambiguous.
