AP/FD COMMON MODES - TAKEOFF
A330/A340 FLEET DSC-22_30-80-20 P 4/4
FCOM 19 AUG 10
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 or if an ILS back course has been selected, 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".

General
GENERAL
Applicable to: ALL
The aircraft can fly different types of approaches:
‐ Precision approaches: ILS, MLS
‐ Non-precision approaches: VOR/DME, VOR, NDB, 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
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 by pressing the APPR pb of the FCU and:
An ILS approach or a runway only or no approach is inserted ‐ in the Flight Management flight
plan (ARRIVAL page), and an ILS frequency is set in on the MCDU, or
‐ Both radio management panels are set to NAV and each one has the ILS frequency and
course set in.
Note: The ILS frequency will be automatically tuned when the direct distance to destination is
below 300 nm.
CHECK APPROACH GUIDANCE MESSAGE
If the flight crew inserts a non-ILS approach in the flight plan and then uses the RAD NAV page
to manually tune an ILS, the MCDU displays the "CHECK APPR GUIDANCE" message. This
message is a reminder that the available APPR guidance modes are APP NAV and FINAL.

Example: OLW was manually entered on the RAD NAV page although a VOR approach is
selected in the flight plan.
APPR MODE
ARMING CONDITIONS OF LOC AND G/S MODES
The flight crew arms the ILS APPR mode (LOC and G/S in blue on the FMA) by pressing the
APPR pb on the FCU, provided that:
‐ An ILS approach is selected
‐ The aircraft is above 400 ft RA
‐ The ILS is available
‐ Go-around or takeoff or final mode is not engaged
‐ ILS frequency and course are identical on both receivers.
LOC and G/S blue are displayed on the FMA. Both modes automatically engage when
conditions are met.
Second autopilot may be engaged.
Current landing capability is displayed on the FMA.
DISARMING CONDITIONS OF LOC AND G/S MODES
ILS APPR mode is disarmed if the aircraft is above 400 ft and meets one of the following
conditions:
‐ When the flight crew presses the APPR pb, both the LOC and the G/S modes disarm. The
HDG/TRK mode engages if the LOC mode was engaged, and the V/S or FPA mode engages
if the G/S mode was engaged
