the most advanced thrust lever position).
Note: 1. When a thrust lever is set between two positions, the FADEC selects the
rating limit corresponding to the highest mode.
2. When idle is selected, the FADEC selects CL.
3. When MREV is selected, the EPR rating limit value is replaced by amber
crosses (MREV mode is limited by N1).
On ground (with engines running) :
• With engines running, on ground, whatever the lever position, this limit corresponds to
the TOGA thrust limit.
• With engines running, on ground, and if FLEX mode is selected, FLEX EPR is
displayed, whatever the thrust lever position between idle and FLEX/MCT.
(4) FLEX temperature
If FLX mode is selected, the flexible takeoff temperature selected through the MCDUs is
displayed in blue.

(A) Actual EGT
‐ It is normally green.
‐ It pulses amber, when EGT above 610 °C, except for high power operation
(FLEX takeoff or thrust lever above MCT or at maximum REV, or activation of
alpha-floor).
‐ It pulses red, when EGT is above 635 °C.
(B) Max EGT :
The amber index appears at 610 °C.
Not displayed during takeoff.
(C) Max permissible EGT :
EGT redline is at 635 °C. A red arc is displayed from 635 °C to the end of the scale.
(D) EGT exceedance :
If EGT goes over 635 °C, a red mark appears at its maximum value. It disappears
after a new takeoff, or after maintenance action through the MCDU.
(6) LP rotor speed (N1)
(A) Actual N1
It is normally in green.
It pulses amber, when N1 is above N1 rating limit.
It pulses red, when N1 is above 100 %.
(B) Max permissible N1
N1 redline is at 100 %. A red arc is displayed from 100 % to the end of the scale.

(C) N1 Exceedance
If N1 exceeds 100 % during a flight, this red mark appears and remains at the
highest N1 attained. It will disappear after a new takeoff, or after maintenance action
through the MCDU.
(7) HP rotor speed N2
The numbers are normally green. (During the start sequence, they are green on a grey
background).
When N2 is above 100 %, the indication turns red and a red cross appears next to it.
The red cross will disappear after a new takeoff, or after maintenance action through the
MCDU.
(8) Fuel flow
It is indicated in green.
At engine shutdown, the FF indication is replaced by amber crosses for about 15 s, prior
to going to zero.
Note: If case of a discrepancy between the real and displayed EGT, N1, N2, or FF
values, an amber CHECK message is displayed near the affected parameter
indication.
(9) IDLE indication
In flight, this legend appears in green when both engines are at idle. It flashes for 10 s,
then remains steady.

(1) Engine Pressure Ratio ( EPR)
(A) Actual EPR
The EPR needle and EPR digital indication are in green.
(B) EPR Command (EPR trend)
The green needle corresponds to the EPR demanded by the FADEC. In addition,
next to the EPR command needle, a green triangle indicates the direction of EPR
tendency.
These symbols are displayed when A/THR is active.

Symbolizes the difference between the EPR command and the actual EPR. It is only
displayed when A/THR is active.
(D) EPR TLA (blue circle)

(E) EPR max
The EPR MAX amber is the EPR limit value corresponding to the full forward

(F) REV indication
It is displayed in amber, when at least one reverser cowl is unstowed or unlocked.
It becomes green, when the reverser cowls are fully deployed and reverse mode is
selected. (If unlocked in flight, the indication first flashes for 9 s and then remains
steady).
(2) Thrust limit mode
The limit mode (TOGA, FLX, MCT, CL, or MREV), selected by the FADEC is displayed in
