V1V2V3VRVS0VS1Thanks Waldo

Hi Waldo,Vs the aircraft's stall speed in clean, or cruise configuration (gear and flaps up). Vso the aircraft's stall speed in dirty, or landing configuration (gear and flaps down). Vx the airspeed that provides the best angle of climb (highest altitude in shortest distance). It is typically a fairly slow speed, and is most useful for taking off over obstacles like trees. Vy the airspeed that provides the best rate of climb (highest altitude in least time). It is faster than Vx, and is most useful for getting to an altitude as quickly as possible (say, to avoid icing). Va the maximum airspeed for turbulence. For a typical light civilian aircraft, Va will be approximately double Vs, to ensure that the plane will stall under acceleration greater than 0 G (0 m/s

Thanks! Great post. Always wondered about a few of those myself.

AHHHHHHHH... :-eekI suddenly had a scary flash back to my PP oral exam. Now that was fun! :-)Nice post Vin, thank you!
