Landing Gear

Question 1

Tail Wheel Landing Gear
1- Where are the main gear located
2- What is the advantage of the increased clearance created from the angle of the fuselage

Answer 1

1- Forward of the CoG
2- Better clearance on non-paved runways

Question 2

How is a tandem landing gear configured

Answer 2

With the main and tail gear aligned on the fuselage

Question 3

Tricycle Landing Gear
1- What are 3 advantages of this gear arrangement
2- How is ground looping prevented
3- What are 2 methods used to control the nose wheel when steering
4- Where is the main gear attached

Answer 3

1- Allows forceful application of brakes without nosing over, enabling higher landing speeds
- Better vis from flight deck
- Prevents ground looping
2- The CoG being forward of main gear, forces acting on CoG tend to keep a/c moving forward rather than looping
3- Differential brakes(castoring nose wheel)
- Nose gear connected through mechanical linkage to rudder pedals in lighter a/c, while larger a/c use hydraulics using a tiller in flight deck
4- Attached to reinforced wing/fuselage structure

Question 4

What is it called when 2 or more wheels are attached to a landing gear strut

Answer 4

A Bogie

Question 5

Why do some light (slower) a/c not use retractable landing gear

Answer 5

The penalty of added weight isn’t overcome by the reduction of drag
