D
Instead of using course error and radio deviation from the SG, a
composite lateral steering command is used from the FMS
navigation computer through the IAC symbol generator function.
D
The IAC supplies the flight control function with required steering
commands.
D
This lateral steering command is lateral gain programmed in the
FMS navigation computer, and therefore, is not gain programmed
again in the IAC.
