Question

(Hydraulics/Landing Gear) If hydraulic system quantity is below ____ or utility pressure is less than ____ after gear extension, perform MANUAL LANDING GEAR EXTENSION checklist to ____.

Answer 1

If the hydraulic system quantity is low or the utility pressure is insufficient after gear extension, the pilot should use the MANUAL LANDING GEAR EXTENSION checklist.

Step-by-step explanation:

If the hydraulic system quantity is below a certain level, or if the utility pressure is less than a specific value after the gear extension, the pilot should perform the MANUAL LANDING GEAR EXTENSION checklist. This checklist will guide the pilot through the steps necessary to manually extend the landing gear.

In a normal approach to landing, we typically extend the gear between 2500 and 1500 feet in order to achieve a “Stable” profile which for most companies must be 1000 feet above the landing runway (300 meters) The distance will typically be around 10-15 nautical miles or 18-25 km.

The emergency extension system lowers the landing gear if the main power system fails. There are numerous ways in which this is done depending on the size and complexity of the aircraft.
