ASI = B L I P D C

S
B = blockage T - tied gyro
G - gimal
H - horizontal
Altimeter = B L I P T B L = leakage
A - axis
R - random wander
I = instrument error A - apparent wander
P = position error R - uses rigidity
P - lat. nut uses precision V - varying rpm
Machmeter = B I P D = density error
T - transport wander
C = compressibility 2 - 2 ° of freedom coz 2
T = temperature error gimbals
VSI = B L I P

DGI principle = T H A R P 2 A- artificial horizon


V- vertical Axis
E- Earth gyroscope
DGI = G R A V T 2- 2 gimbal i.e 2° freedom

Artificial horizon = A V E 2
T- TSI
TSI = T H A P 1 H- horizontal
A- Axis
P- precision
Magnet = A T P L M A 1 - I freedom as in 1 gimbal
A- acceleration error
T - turning error
P - parallax error
L - liquid swirl
M - misalignment
A - altitude error
