PRIMARY PARAMETER
(1) LP rotor speed (N1)
(A) Actual N1
The N1 needle and N1 digital indication are :
‐ Normally green
‐ Amber, when the actual N1 is above the N1 MAX (See E)
‐ Red, when the actual N1 is above the N1 RED line (104.2 %).
When N1 is degraded (in case both N1 sensors fail), the last digit of the digital display
is amber-dashed.
(B) N1 Command (N1 tendency)
The green needle corresponds to N1 demanded by the FADEC. In addition, next to
the N1 trend needle a green triangle indicates the direction of N1 tendency. These
symbols are only displayed when A/THR is active.

(C) Transient N1
Symbolizes the difference between the N1 command and the actual N1. It is only
displayed when A/THR is active.
(D) N1TLA (blue circle)
N1 corresponding to the thrust lever position (predicted N1).
(E) N1 MAX
Amber index at the value corresponding to the N1 limit value of the TOGA or REV
mode.
(F) Max permissible N1
N1 redline is represented by a red arc at the end of the scale, beginning at 104.2 %.
(G) N1 exceedance
If 104.2 % is exceeded, a red mark appears and remains at the maximum value
achieved. It will disappear after a new start on ground, or after maintenance action via
the MCDU.
(H) REV indication
The REV indication appears in amber when one reverser is unstowed or unlocked. lt
changes to green when the doors are fully deployed and reverse mode is selected. (If
unlocked in flight, the indication first flashes for 9 s and then remains steady).
(I) AVAIL indication
Displayed in green to indicate a successful engine start on ground.
It pulses in green to indicate a successful engine relight in flight.
It is triggered when the engine is at, or above, idle.
(2) Thrust limit mode
TOGA, FLX, CLB, MCT, limit mode, selected by the thrust lever, is displayed in blue.
(3) N1 rating limit
Computed by the FADEC, according to the thrust lever angle, and is displayed in green.
Note: The highest thrust limit mode of the four ‐ engines, and its associated N1 limit
value, is displayed.
‐ On ground, with the engines running, the displayed N1 rating limit corresponds to
the TOGA thrust limit, whatever the thrust lever position may be.
On ground, with the engines running and if FLEX mode is selected, FLEX N1 is
displayed, whatever the thrust lever position may be, between IDLE and FLX /
MCT.

(4) FLEX temperature
If a FLEX temperature has been entered via the MCDU and validated by the FADEC, this
temperature is displayed in blue.
(5) EGT indicator
(A) Actual EGT
‐ Normally green
‐ Becomes amber above 915 °C (or above 725 °C during start sequence) except for
high power operation (FLEX takeoff or thrust lever above MCT or at maximum REV,
or activation of alpha–floor).
‐ Becomes red above 950 °C.
(B) EGT Max (amber)
725 °C at engine start then 915 °C.
(C) Max permissible EGT
EGT red line is at 950 °C. A red arc is displayed above 950 °C to the end of the scale.
(D) EGT exceedance
If 950 °C is exceeded, a red mark appears at the max value achieved. It will disappear
after a new start on the ground or after a maintenance action through the MCDU.
(6) HP rotor speed N2
Digital indication normally green is over brightning during engine start and located in a grey
background box.
When the N2 is above 105 % the indication becomes red and a red cross appears next to
the digital indication. The red cross will disappear only after a new start on ground or after a
maintenance action through the MCDU.
When the N2 value is degraded (in case of a dual N2 sensor failure), the last digit is amber
dashed.
(7) Fuel flow
Green indication
(8) A FLOOR message
Is displayed amber when the ECUs receive the corresponding signal from FMGS.
