Airspeed Color Coding And V Speeds Flashcards
(Color coding and V speeds ) red line
Indicates the maximum speed the airplane can be operated in smooth air.
Referred to as V NE
(Color coding and V speeds ) the yellow arc
Operation only in smooth air- avoid during turbulent conditions
(Color coding and V speeds ) white arc
there are a series of v speeds.
Shows us the speed range we can operate the flaps in.
(Color coding and V speeds ) The beginning of the white arc what is called and show ?
VSO , shows the stall speed in landing configuration at the slowest speed without running out of lift , which would result in a stall.
(Color coding and V speeds ) what is the edge of the top of the white arc
VFE , flap extension speed. don’t want to go any faster than VFE with flaps deployed.
- could bend metal and cause damage to our flaps.
(Color coding and V speeds ) Green arc shows ?
Normal operating range
Most of your flying will be done here where you want to be if its bumpy
The bottom of the Green arc = VSi lower velocity side of green arc , tall speed in CLEAN configuration.
The Top of the green ac is VNO Normal operating speed , don’t exceed this speed unless the air is smooth
(Color coding and V speeds ) what is the yellow arc show ?
The caution range
Operation in smooth air only
Avoid during turbulent conditions
(Color coding and V speeds ) what is the airspeed that is not measured on the airspeed indicator ?
Maneuvering Speed - V A
Speed at which abrupt control movements can be made without structural damage.
The HEAVIER. The airplane is , the HIGHER. The manuvering speed will be . Manuvering speed changes with weight.
Airspeed indicator description from the air going in to the the pitot tube .
RAM AIR enters the pitot tube
Air strikes a diaphragm inside the airspeed indicator
This activates a series of shafts and linkages and rotates the pointer on the dial .
