Flashcards in ASI Deck (14):
1kt is also equal to?
1.151SM/hr ('miles per hour')
ASI uses which pxs?
Dynamic and static px.
white arc indicates -
Flap operating range
Lower end VS0
Higher end VFE
Green arc -
Normal operating speed range
Lower end: VS1
higher end VNO
VNE is the never exceed speed
What do the blue and 2nd red line indicate in a light twin?
Both blue and 2nd red line are in the slower speed range.
Blue = VYSE
2nd red = VMCA
To calibrate the ASI, it has to be set at a px level, but this will only be accurate if S and L so...
ASI under reads the TAS at altitude.
The discrepancy is called density error. If below MSL, the ASI will over read the TAS.
What errors are there on an altimeter?
Compressibility (> 300TAS)
What acronym is used for blockages in an ASI?
Pitot blocked, under read (capsule contracts)
Static blocked, over read (capsule expands)
What happens to the ASI when there is a pitot leak?
Under reads (within px hull)
Over reads (outwith
Compressibility in an ASI will cause the ASI to...
VFE is the max speed that....
The flaps can be operated.
VLE is the max:
Flight speed with LDG gear down
