text: The tricycle landing gear configuration has 
  an inherent stability d,ue to the relative posi- 
  tion of the main wheels and the center of 
  force produced by a 
  gravity. 
  turn is balanced by the side force on the main 
  wheels and a side force on the nose wheel in 
  the direction of turn. Note that the freeing 
  the nose wheel to swivel produces moments 
  which bring the aircraft out of the turn. Thus, 
  the tricycle configuration has a basic stability 
  which.is given evidence by control displace- 
  ment and a wheel side force in the direction 
  of turn. Because of the contrast in stability, 
  the tricycle configuration is much less difficult 
  to maneuver than the tail wheel configuration 
  and does not provide an inherent ground loop 
  tendency. However, a steerable nose wheel 
  is usually necessary to provide satisfactory 
  maneuvering capabilities.
