Hydraulic System Operation - The low pressure switch monitors the hydraulic system fluid pressure. It will make the Crew Alerting System (CAS) show a Hydraulics caution if the hydraulic system fluid pressure falls to below _____.
A shimmy damper is installed on the nose landing gear strut to eliminate nosewheel oscillations.
The Crew Alerting System (CAS) will show a Hydraulics caution in flight after the power pack has been automatically initiated more than six times in an hour by the system pressure switch in order to maintain system pressure.
The Crew Alerting System (CAS) will show a Hydraulics caution for two different functions: In flight a continuous Hydraulics caution means that the power pack pump has been operating for more than 2 minutes or the main system pressure has fallen below operational limits (nominal 1,800 psi) and cannot be relied upon for proper landing gear system operation. The Hydraulics caution is given 30 seconds after the pump has been operating for more than 2 minutes or low pressure is sensed by a low pressure switch mounted in the power pack pressure supply line upstream of the landing gear selector valve. On ground after landing a continuous Hydraulics caution means that the power pack has been automatically initiated in flight more than six times in an hour by the system pressure switch in order to maintain system pressure. This indicates that the pressure leak rate from the system is too high or a low fluid level condition exists. Pilot initiated landing gear cycle will reset this counter to zero when there are less than six counts in an hour.
The landing gear is a conventional tricycle configuration that is extended and retracted using hydraulic pressure produced by an electrically powered hydraulic pump. Landing gear extension and retraction is the only function of the hydraulic system.
The nose gear doors are spring loaded to the open position and are hydraulically closed during nose gear retraction.
The nose gear doors are spring loaded to the open position and are mechanically closed during nose gear retraction. The nose gear retracts rearward into the nosewheel well and is completely enclosed by the gear doors when the landing gear is retracted.
Landing gear position is shown by three icons (one for each gear) in the GEAR window of the systems MFD. What is the meaning of this white hatched lines with red background display?
Landing gear position is shown by three icons (one for each gear) in the GEAR window of the systems MFD. What is the meaning of this white hatched lines with black background display?
Landing gear position is shown by three icons (one for each gear) in the GEAR window of the systems MFD. What is the meaning of this amber cross on black background display?
Emergency Extension System - If the landing gear does not completely extend and show three green indicators, pull the emergency landing gear hand pump handle out of the aft center console and begin pumping. Stop pumping when all three landing gear indicators show green. Experience has shown that approximately _____ of the hand pump are required to fully extend the landing gear.
The pilot will stow the emergency landing gear hand pump handle back into the aft center console before landing. If necessary, yawing the airplane to use the aerodynamic load may assist the emergency extension.
Nosewheel steering is accomplished by mechanical nosewheel steering and by differential braking.

Nose wheel steering is accomplished using the rudder pedals which are mechanically connected to the nosewheel. Additional nosewheel steering is done through differential braking. Use of rudder pedal only will turn the nosewheel plus or minus _____ from center while differential braking will turn the nosewheel plus or minus 60 degrees from center.
Hydraulic System Operation - The system pressure switch monitors the hydraulic system accumulator pressure and controls the operation of the power pack pump. When the pressure in the hydraulic system accumulator is less than _____ the system pressure switch operates and starts the power pack pump.
When the pressure in the hydraulic system accumulator is between 2725 and 2875 psi the system pressure switch operates and stops power pack pump.
Emergency Extension System - To manually extend the landing gear, set the landing gear selector handle to DN with airspeed less than _____ (power to idle momentarily).
This will allow the landing gear to free fall.
