AIRSPEEDS NORMAL OPS Flashcards
KCAS
Knots calibrated airspeed…indicated airspeed corrected for position and instrument error, is equal to KTAS IN STD ATMOSPHERE AT SEA LEVEL
KIAS
Knots indicated airspeed
…speed shown in the airspeed indicator
KTAS
Knots true airspeed
…calibrated airspeed corrected for altitude and temperature
Va (Vo)
MANEUVERING SPEED in PIPER (PA-28) referred as:
Vo-MAXIMUM OPERATING MANEUVERING SPEED
…is the maximum speed at which full aerodynamic control will not overstress the airplane
(Vo at 1,634 lbs: 89KIAS)
( Vo at 1,917 lbs: 98KIAS)
(Vo at 2,550 lbs: 113KIAS)
Vfe
MAXIMUM FLAP EXTENDED SPEED
…is the highest speed permissible with flaps at an extended position (Vfe-102KIAS)
Vlof
LIFT OFF SPEED
…speed at which the airplane should be rotated to climb attitude during takeoff run (Vlof-60KIAS)
Vne
NEVER EXCEED SPEED
…is the speed limit that may not be exceeded at any given time (Vne-154KIAS)
Vno
MAXIMUM STRUCTURAL CRUISING SPEED
…is the speed that should not be exceeded except in smooth air with caution (Vno-125KIAS)
Vs
STALLING SPEED or MINIMUM STEADY FLIGHT SPEED
…is the minimum speed at which the airplane is controllable (Vs-50KIAS)
Vso
STALLING SPEED or MINIMUM STEADY FLIGHT SPEED (landing configuration & Cg)
…is the minimum speed at which the airplane is controllable in the landing configuration at a the most forward center of gravity (Cg) (Vso-45KIAS)
Vx
BEST “ANGLE” (x-horizontal) OF CLIMB SPEED
…is the speed at which results in the greatest gain of altitude in a given HORIZONTAL distance (Vx-64KIAS)
Vy
BEST “RATE” (y-time) OF CLIMB SPEED
…is the speed at which results in the greatest gain of altitude in a given TIME (Vy-76KIAS)
Vg
BEST GLIDE SLOPE
…speed at which the airplane can glide slope (Vg-76KIAS)
IFR HOLDING PATTERN
90 KIAS
IFR APPROACH
75 KIAS
