PC-21 Airspeed Limitaitons

Question 1

Maximum Operating Speed Vmo / Mmo

Answer 1

Vmo = 370 KIAS
Mmo = 0.72M

Do not exceed this airspeed or mach number in any operation

Question 2

Manoeuvring Speed Vo

Answer 2

370 KIAS

Question 3

Manoeuvring Speed for aileron/rudder

Answer 3

220 KIAS

Do not make full and/or abrupt control movements above this speed

Between 220 and 370KIAS, the pedal deflection must be linearly reduced from 100% to 30% maximum pedal travel

Abrupt = Control movement from neutral to full deflection in less than 1s

Question 4

Maximum speed with flaps and/or landing gear extended/operating V(FE), V(LO), V(LE)

Answer 4

180 KIAS

Do not extend or retract the landing gear and/or flaps above this speed

Do not exceed this speed with landing gear or flaps extended

Question 5

ASI Red line

Answer 5

370 KIAS

Max speed for all operations

Question 6

ASI Green arc

Answer 6

97 to 370 KIAS

Normal operating range. Lower limit is stall speed at max weight with flaps and landing gear retracted

Upper limit is max operating speed limit

Question 7

ASI White arc

Answer 7

86 to 180 KIAS

Full flap operating range

Lower limit is maximum weight stalling speed in landing configuration

Upper limit is max speed permissible with flaps extended

Question 8

Weather Penetration

Answer 8

200 KIAS

Question 9

Turbulence Penetration

Answer 9

160 to 200 KIAS

Question 10

Manoeuvring speed for elevator

Answer 10

220 KIAS

Do not make abrupt control movements to full deflection above this speed

For control inputs at speeds faster than 220 KIAS, the G limit must be respected
