Function
Filter Offset Filter
Output Value = Filter [Convert Source A in
Pressure to Altitude + Offset]
Note: Pressure Altitude calculation is based on
the International Standard Atmosphere 1976.
Source A is a pressure signal and needs to be in
PSI units for the calculation. The calculation is
accurate from sea level to 90,000 feet. It can be
used beyond this range in both directions, but
with loss of accuracy. The standard is based on
an altitude of 0 feet (sea level) pressure of
14.6967 PSI and a temperature of 59 degrees F.
Result of calculation is in feet.
