Designmaneuvering speed. This is the speed above which it is unwise to make full application of any single flight control (or “pull to the stops”) as it may generate a force greater than the aircraft’s structural limitations.

A. VB
Indicated airspeed at threshold, which is usually equal to the stall speed VS0multiplied by 1.3 or stall speed VS1gmultiplied by 1.23 in the landing configuration at the maximum certificated landing mass, though some manufacturers apply different criteria.

C. VLO
Lift-off speed.
A. VA B. VLE C. VLOF
C. VLOF
Minimum control speed. Mostly used as the minimum control speed for the take-off configuration (take-off flaps) in many publications. Several VMC’s exist for different flight phases and airplane configurations: VMCG, VMCA, VMCA1, VMCA2, VMCL, VMCL1, VMCL2. Refer to the minimum control speed article for a thorough explanation.
A. VA B. VMC C. VLO
B. VMC
Minimum control speed in the air (or airborne) for maintaining steady straight flight when an engine fails or is inoperative and with the corresponding opposite engine set to provide maximum thrust, provided a small (3° – ) 5° bank angle is being maintained away from the inoperative engine and the rudder is used up to maximum to maintain straight flight.
A.VMCA B. VMC C. VLO
A.VMCA
Minimum control speed on the ground is the lowest speed at which the take-off may be safely continued following an engine failure during the take-off run.
A.VMCA B. VMC C. VMCG
C. VMCG
Minimum control speed in the landing configuration with one engine inoperative.
A.VMCA B. VMC C. VMCL
C. VMCL
Maximum operating limit speed.
A. VMO B.VMC C. VMCL
A. VMO
Minimum unstick speed. It is achieved by pitching the aircraft up to the maximum (tail on the runway, for aircraft that are geometrically-limited) during the take-off roll.
A. VMO B.VMC C. VMU
C. VMU
Never exceed speed.
A. VNE B.VMC C. VMCL
A. VNE
Maximum structural cruising speed or maximum speed for normal operations.
A. VNE B.VMC C. VNO

A. VO
Rotation speed. The speed at which the aircraft’s nose wheel leaves the ground during
take-off.
A. VR B.VMC C. VNO
A. VR
Used instead of VR (in discussions of the take-off performance of military aircraft) to denote rotation speed in conjunction with the term VRef (refusal speed).
A. VNE B.Vrot C. VNO
B.Vrot
Landing reference speed or threshold crossing speed.
Stands for refusal speed for military aircraft. Refusal speed is the maximum speed during take-off from which the air vehicle can stop within the available remaining runway length for a specified altitude, weight, and configuration.
