MAINTENANCE MANUAL
(9) Outside Air Temperature “OAT”
(a) QDI ( S/N’s 4636021 thru 4636131 only ).
1 The “OAT” reading will be posted on the LCD when this function is manually
selected.
2 To post the “OAT” reading, press the “N” button with the “OAT” adjacent to it. The
“OAT” reading is displayed in degrees C. (See Figure 6.)
3 To exit from this mode, select any analog indicator from the EMIS system stack, or
any other function button of the QDI.
NOTE: Since the pushbutton designated for the "OAT" display has a secondary
function during exceedance review mode, the "OAT" display mode is
disabled during that mode of operation.
(b) EDI ( S/N’s 4636132 thru 4636374 ).
1 “OAT” is the default display in the left LCD when in the INST mode. (See Figure 4.)
2 When in INST mode, the “OAT” display can be cycled from “° F” to “° C” by pressing
the SET button.
(10) Fuel Imbalance Alarm
If a fuel imbalance greater than 10 gallons is sensed between the left and right fuel tanks, the
alarm output (for an external annunciator) will be activated after 60 seconds. As soon as the
imbalance is corrected, the alarm will deactivate.
(11) Automatic Exceedance Warning Mode
(a) The exceedance warning mode has the highest priority. When an exceedance is detected,
the QDI/EDI will automatically select that indicator and display the readings on the LCD.
The peak exceedance value of the indicator will flash in the display.
NOTE: The QDI/EDI will automatically select and display exceedances in the order they
are detected. Low exceedance recording and the alarm outputs of the VAC and
OP analog indicators will be suppressed until the engine reaches a speed of
1400 RPM.
