current altitude, the aircraft will remain in SRS mode until the flight crew takes some
other action.
RUNWAY (RWY)
Applicable to: ALL
GENERAL
The RUNWAY mode has two submodes:
RWY mode, which gives lateral guidance ‐ orders during takeoff roll and initial climb out (up to
30 ft RA) if a LOC signal is available
‐ RWY TRK mode, which gives lateral guidance on the track the aircraft was flying at mode
engagement (at 30 ft RA).

ENGAGEMENT CONDITIONS
The RWY engagement conditions are:
‐ The conditions required for SRS mode engagement:
• V2 is inserted in the MCDU PERF TAKEOFF page
• Slats are extended
• The aircraft has been on ground for at least 30 s.
‐ The aircraft is receiving a LOC signal and LOC deviation is less than 1/2 dot
‐ The aircraft heading is within 20 ° of the ILS related course
‐ The ILS course is identical to the runway heading of the origin airport as selected for the active
flight plan, if any.
The RWY TRK mode engages automatically at 30 ft (RA) if NAV mode does not engage (NAV not
armed prior to takeoff).
DISENGAGEMENT CONDITIONS
RWY mode disengages if:
‐ The LOC signal is lost below 30 ft RA or the aircraft heading and the runway heading differ by
more than 20 °.
‐ Another lateral mode is engaged.
Note: If the takeoff runway has no ILS, RWY mode is not available and the PFD does not
display the yaw bar nor "RWY" on FMA.
GUIDANCE
The RWY mode uses the LOC signal to guide the aircraft on the runway centerline while the
aircraft is on the ground. The PFD displays the FD yaw bar and the FMA displays "RWY".
The RWY TRK mode guides the aircraft on the track the aircraft was flying at mode engagement.
The FD displays the conventional guidance bar and the FMA displays “RWY TRK”.

The aircraft can fly different types of approaches:
‐ Precision approaches: ILS, MLS
‐ Non-precision approaches: VOR/DME, VOR, NDB (if ADF ), RNAV
‐ Non-precision approaches using a Localizer only: LOC, LOC B/C.
The flight crew uses an ARRIVAL lateral revision to insert these approaches into the flight plan:
‐ For precision approaches, the flight crew uses the APPR pb on the FCU to arm or engage the
LOC and G/S guidance modes
‐ For non-precision approaches, the flight crew uses the APPR pb on the FCU to arm or engage the
APP NAV and FINAL guidance modes, except for LOC and LOC B/C approaches, where the flight
crew only uses the LOC pb to arm or engage the LOC mode.

PRECISION APPROACH MODES
Applicable to: ALL
GENERAL
The ILS approach mode includes the following modes:
VERTICAL MODE LATERAL MODE
G/S* (capture)
G/S (track)
LOC* (capture)
LOC (track)
COMMON MODES:
LAND - FLARE - ROLL OUT
The sequencing of these modes is automatic once the flight crew has pushed the APPR pb and
the conditions for engagement are met.
SELECTION
The ILS approach is selected when the APPR pb of the FCU is pressed and:
