13.16 Landing Gear

The advantages of a nose L/G are….

• AofA nearly 0 on landing

• Permits more forceful application of brakes on landing

• Reduces skidding

• Better vision when taxiing

In direct nose wheel steering rudder pedals permit how much deflection each way (in degrees)

• 5 degrees
• 10 degrees
• 3 degrees
• 15 degrees

In indirect nose wheel steering you can steer up to how many degrees in each direction at slow speeds?

• 10 degrees
• 90 degrees

• 30 degrees

• 80 degrees

What provides dampening in an aircraft undercarriage shock strut?

• Metal springs
• Hydraulic fluid

• Nitrogen

What provides the spring in an aircraft undercarriage shock strut?

• Steel springs
• Hydraulic oil

• Nitrogen

• Magnetic force

Why do we only use spherical bearings in an undercarriage shock strut?

• Spherical bearings improve fuel efficiency in undercarriage shock struts.
• Spherical bearings do not transmit torque when transmitting vertical and drag loads.

• Spherical bearings reduce weight and cost in undercarriage shock struts.
• Spherical bearings transmit torque when transmitting vertical and drag loads.

What is used to stop wheel shimmy on an aircraft undercarriage?

• Side strut

• Drag strut

• Shock absorber
• Torsion link Damper

How does a Downlock keep an undercarriage leg down and locked?

• Gravity

• Unlock spring

• Geometric lock

• It uses a magnetic field to attract the leg

In body gear, what direction do the main undercarriage move in to prevent scrubbing of the tyres when the nose wheel is moved?

• Left

• Same direction as the nose wheel
• Opposite direction of the nose wheel
• Right

What disengages the nose wheel steering when the wheel is centered and the aircraft is airborne?

• Landing gear lever
• Interconnect

• Speed brake lever
• Altitude switch
