General
Additional fuel metering valve (FMV) and variable stator vane
(VSV) parameters show on these CDU pages. You see these
pages when you select FMV or VSV from the INPUT
MONITORING CONTROL LOOPS page.
The ACT CH A shows the active channel or the channel that
controls the engine. The GMM CH A shows the ground
maintenance mode (GMM) channel or the channel that
controls CDU BITE.
FMV
The FMV pages show you the fuel metering valve demand and
position values for channel A and B. The SIN and COS values
are voltages from the resolver feedbacks. The OUT and IN
values for channels A and B are the torque motor demand and
return path current values.
VSV
The VSV pages give you the variable stator vane demand and
position the EEC senses for channel A and B. The V1 and V2
values are voltages from the linear variable differential
transformer (LVDT) feedbacks. The OUT and IN values for
channels A and B are the torque motor demand and return path
current values.
Training Information Point
If a parameter is not available, (?) symbols are put in place of
the parameter. If the parameter is out of range, (-) symbols are
put in place of the parameter.

General
More variable bleed valve (VBV) parameters show on these
CDU pages. The VBV DATA pages give you the VBV demand
and position values for channel A and B. You see these pages
when you select VBV from the INPUT MONITORING CONTROL
LOOPS page.
The ACT CH A shows the active channel or the channel that
controls the engine. The GMM CH A shows the ground
maintenance mode (GMM) channel or the channel that
controls CDU BITE.
The V1 and V2 values are voltages read from the LVDT
feedback. The OUT and IN values for channels A and B are the
torque motor demand and return path current values.

General
More high pressure turbine active clearance control (HPTACC)
and low pressure turbine active clearance control (LPTACC)
parameters show on these CDU pages. You see these pages
when you select HPTACC or LPTACC from the INPUT
MONITORING CONTROL LOOPS page.
The ACT CH A shows the active channel or the channel that
controls the engine. The GMM CH A shows the ground
maintenance mode (GMM) channel or the channel that
controls CDU BITE.
HPTACC DATA
The HPTACC DATA pages give you the high pressure turbine
active clearance control demand and position values for
channel A and B. The V1 and V2 values are voltages from the
