1. EPR LIM READOUT
Displays digital readout of EPR limit for
selected operating thrust rating mode.
2. CMD EPR REFERENCE READOUT
Digital readout of EPR reference as set with
EPR reference set knob. The EPR reference
bug is set in correspondence with CMD EPR
Reference readout when manual mode is
selected. The manual EPR reference readout
will only be displayed when manual mode is
active.
3. EPR POINTER
Indicates current operating EPR of engine.
Digital EPR readout displays corresponding
value.
4. EPR REFERENCE BUG
Indicates reference EPR. Manually set with
the EPR reference set knob, or automatically
set according to the selected EPR limit thrust
mode on the Thrust Rating Panel.
5. EPR READOUT
Digital readout of current operating engine
pressure ratio of engine. EPR pointer displays
corresponding value.
6. ASSUMED TEMPERATURE SELECTOR
Rotate knob to set assumed temperature for
the TO FLX mode. Temperatures from 0 to
59°C or 0 to 140°F can be selected. The set
assumed temperature is displayed on the
FMA when TO FLX mode is selected.
7. TRP MODE SELECT BUTTONS
TO
If the ART switch is in AUTO, pushing
the TO mode button will cause the
max take-off EPR limit to be
displayed on the EPR LIM readout.
If the ART switch is in the OFF
position, pushing the TO mode
button will cause a computed
reserve thrust EPR limit to be
displayed on the EPR LIM readout.
TO FLX Pushing the TO FLX mode button
will cause a reduced EPR limit to be
displayed on the EPR LIM readout.
Reduced EPR limit is determined by
selecting an assumed temperature
that is higher than ambient
temperature. When a mode other
than TO FLX is selected, the
assumed temperature is reset to
zero.
