V-speeds

Question 1

V(y)

Answer 1

Best rate of climb speed.
Allows pilot to clim to altitude in shortest time.
@ sea level 96 Kias
@ 10,000 92 KIAS

Question 2

V(X)

Answer 2

Best angle of climb.
Allows one to climb to altitude wishing the shortest horizontal distance
81Kias

Question 3

V(S)

Answer 3

Stall speed clean

71KIAS

Question 4

V(SO)

Answer 4

Stall speed full flaps

62KIAS

Question 5

V(O)

Answer 5

Operating maneuvering speed
@3150- 133KIAS
@2600- 120KIAS

Max speeds at which full control travel may be used.
Below this speed the airplane stalls before limit loads can be reached.
Above this speed full control movements can damage airplane

Answer 8

Never exceed speed.
201KIAS
(RED ARC)

Question 9

V(NO)

Answer 9

Max structural crushing speed.
164KIAS
Thins speed should not be exceeded except in smooth air, and even then, with great caution.
(Start of yellow arc)

Question 10

Yellow arc

Answer 10

KIAS 164-201

Caution range. Operations must be conducted with caution and only in smooth air.

Question 11

Red arc

Answer 11

KIAS 201+

Never exceed speed. V)NE)
Max speed of aircraft

Question 12

Green Arc

Answer 12

KIAS 71-164
Normal operating range.
Lower limit is max weight stall speed with flaps clean.
Upper limit is V(NO) (max structural crushing speed)

Question 13

White arc

Answer 13

62-110
Full flap operating range. Lower limit (62KIAS) is stall speed with full flaps V(SO)
Upper limit (110KIAS) is max speed permissible with flaps fully extended
