When would you use the Alternate gear extension procedure?

• A. If hydraulic pressure is not available for gear operation or the electrical system fails
• B. When hydraulic pressure is normal
• C. Only when gear doors jam
• D. When the aircraft is on the ground

Answer: (A)

Alternate gear extension provides a backup path to extend and lock the landing gear when the normal hydraulic path isn’t available or the electrical system has failed. That’s why this option is the best: it directly addresses scenarios where the primary gear extension method can’t operate due to loss of hydraulic pressure or loss of electrical power, ensuring you can still get the gear down for landing. If hydraulic pressure is normal, you rely on the standard extension system; gear-door jams and being on the ground don’t define the need for the alternate method, and the procedure isn’t about those conditions.
