1
Q
Lower end of the VFE section
A
Vso - stall speed at AUW (max all up weight)
2
Q
Green arc
A
From vs1 to vno
3
Q
Light twin vsi red and blue lines in the slow speed section
A
Red - VMCA
Blue - VYSE
4
Q
Reading TAS at altitude
A
Under - reads due to density error
5
Q
Errors with the ASI
A
IMP
Compressibility - CAS to EAS
Density - EAS to TAS
6
Q
Blockages in the descent
A
PUD - pitot blocked will cause an under read
SOD - static blocked will cause an over read
7
Q
Blockages during the climb
A
POC - pitot will cause an over read
SUC - static will cause an under read
8
Q
Leakage in the lines to the ASI
A
Within the pitot line - under read due to less pitot
Static within the pressure hull - oppose the pitot and under read
