The EPRT receives label 242 (total
pressure) and label 206 (airspeed)
normally from the on-side DADC.
The EPRT will use the cross-side
DADC when the on-side is invalid.
Left EPRT: J1-11 = open, J1-47 =gnd
Right EPRT: J1-11 = grid, J1-47= open
The trimplug discretes adjust the
outputed (trimmed) EPR by the following
equation:
Trimmed EPR = ((EPR - 1) * MF) + 1
Multiplication factor (MF) is
determined by the following table:
(parity -- odd)
