V Speeds

Question 1

Vr

Answer 1

Rotation Speed

Question 2

VLOF

Answer 2

1) Lift‐off speed.
2) Airplane leaves the surface.
3) Some manufacturers reference takeoff performance data to VR, others to VLOF.

Question 3

VX

Answer 3

Best angle of climb speed.

Question 4

VXSE

Answer 4

Best angle‐of‐climb speed with one engine inoperative.

Question 5

VY

Answer 5

Best rate of climb speed.

Question 6

VSSE

Answer 6

1) Safe, intentional one‐engine‐inoperative speed.

2) minimum speed to intentionally render the critical engine

Question 7

VYSE

Answer 7

1) Marked with a blue radial line

2) Best rate‐of‐climb speed with one engine inoperative.

Question 8

what is the legal requirements for VSSE?

Answer 8

Required by 14 CFR Part 23, Airworthiness Standards, to be established and
published in the AFM/POH.

Question 9

VMC

Answer 9

1) Minimum control speed with the critical engine inoperative.
2) Marked with a red radial line

Question 10

What is the purpose of VMC?

Answer 10

1) Only for directional control. 2) There is no requirement that the airplane be
capable of climbing at this airspeed.

Question 11

What do you need to do if engine fails below VMC?

Answer 11

1) on the ground, the takeoff must be rejected.

Question 12

Engine out below VMC, how can you keep the directional control?

Answer 12

promptly closing both throttles and using rudder and brakes as required.

Question 13

what is the first priority after the take off?

Answer 13

1) gain altitude as rapidly as possible.
2) Once leaving the ground, altitude gain is
more important than achieving excess of airspeed
