V speeds

Question 1

V1

Answer 1

The speed beyond which takeoff should no longer be aborted.

Question 2

V2

Answer 2

Takeoff safety speed. The speed at which the aircraft may safely be climbed with one engine inoperative.

Question 3

VA

Answer 3

Design maneuvering 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.

Question 4

VRef

Answer 4

Landing reference speed or threshold crossing speed.

Question 5

VX

Answer 5

Speed that will allow for best angle of climb

Question 6

VY

Answer 6

Speed that will allow for the best rate of climb

Question 7

VYSE

Answer 7

Best rate of climb speed with a single operating engine in a light, twin-engine aircraft – the speed that provides the most altitude gain per unit of time following an engine failure, while maintaining a small bank angle that should be presented with the engine-out climb performance data

Question 8

Vsse

Answer 8

Safe single-engine speed

Question 9

VMCA

Answer 9

Minimum control speed air. The minimum speed that the aircraft is still controllable with the critical engine inoperative[18] while the aircraft is airborne. VMCA is sometimes simply referred to as VMC.

Question 10

VLO

Answer 10

Maximum landing gear operating speed. This is the maximum speed at which the landing gear on a retractable gear aircraft should be extended or retracted

Question 11

VLE

Answer 11

Maximum landing gear extended speed. This is the maximum speed at which a retractable gear aircraft should be flown with the landing gear extended.

Question 12

VFE

Answer 12

Maximum flap extended speed.

Question 13

VNE

Answer 13

Never exceed speed

Question 14

VMO

Answer 14

Maximum operating limit speed.

Question 15

VB

Answer 15

Design speed for maximum gust intensity.

Question 16

MMO

Answer 16

Maximum operating Mach number.
