Vs
Stalling speed or minimum steady flight speed is the minimum speed at which a/c is controllable
Vso
stalling speed/minimum steady flight speed is the minimum speed at which the airplane is controllable in the landing configuration at the most forward centre of gravity
Vx
best angle of climb speed is the speed which results in greatest gain of altitude in a given horizontal distance
Vy
best rate of climb speed which results in the greatest gain in altitude in a given time
Static RPM
engine speed attained during a full throttle engine runup when the airplane is on the ground and stationary
Demonstrated Crosswind Velocity
velocity of the crosswind component for which adequate control of the airplane during takeoff and landing during the demonstrated test
Usable Fuel
- fuel available for flight planning
Unusable Fuel
- quantity of fuel that can not be safely used in flight
Course Datum
- compass reference used by the autopilot, along with course deviation, to provide lateral control when tracking a navigation signal
Reference Datum
- imaginary vertical plane from which all horizontal distances are measured for balance purposes
