WCM Forum - Probleme mit PSS A330 und LOC

Wie aktiviere ich den LOC-Schlater im Anflug??
Aktiviert ist AP1, Auto Throttle, FD und ILS. Vorhin war es beim Anflug auf EDDF in 4000ft Höhe und 200kt Speed.
Gibts bestimmte Höhen oder Geschwindigkeiten, bei denen der LOC aktiviert werden kann? Jedesmal rauscht die Büchse am ILS-Pfad vorbei und ich kann nix machen außer ihn manuell auf den Endanflug zu bringen, was meistens im Durchstarten endet.

Es gibt keinen „ILS-Modus“ das Autopiloten. Wenn die auf „ILS“ drückst, hat das nur etwas mit der Darstellung im PFD zu tun. (Gleiches gilt für die ADF-VOR Select Switches: Die regeln lediglich die Darstellung im ND)

Wenn du den LOC Schalter auf der FCU drückst, folgt die Maschine nur dem Localizer. Mit dem APR Schalter armst du LOC und G/S.

Das ILS fängst du mit Conf 1 und S Geschwindigkeit ein. Dann die Fahrt reduzieren. Das Fahrwerk kannst du 2000ft über Grund ausfahren.

Hier ein paar Auszüge aus der „Bedienungsanleitung“:

UPON REACHING THE INITIAL AREA
ACTIVATE the APPROACH PHASE, either

Automatically, when flying over the DECEL pseudo waypoint (NAV/APPR NAV or LOC* or LOC mode engaged), or

Manually on the PERF page, when the HDG mode is engaged, if an early deceleration is required, or when flying a go-around.

MANAGED SPEED
CHECK that managed speed is active : MONITOR the target speed.

Note : The aircraft decelerates automatically at DECEL pseudowaypoint when managed speed is active and NAV mode is engaged (DECEL point displayed in magenta).
During the approach, the autothrust maintains the maneuvering speed of the current configuration. (GD, S, F, VAPP).

INTERMEDIATE/FINAL APPROACH (ILS approach entered in the F-PLN)
The preferred technique for flying an ILS approach is to fly a decelerated approach using the AP/FDs, the LOC and G/S modes, autothrust in the SPEED mode, managed speed target is recommended.
Decelerated approach
The decelerated approach technique brings the aircraft down to 1 000 feet, at VAPP. In most cases, the interception of the final descent path is achieved with Conf 1 at S speed.

The approach must be stabilized at approach speed (mini ground speed) in the landing configuration before reaching 1 000 feet AGL.
APPROACH MODE ACTIVATION (LOC - G/S)
When cleared by ATC and when appropriate :
PRESS the APPR pushbutton to arm the APPR mode for the approach entered in the flight plan.

Note : If a non precision approach is selected in the active flight plan and if the pilot manually tunes an ILS on the RAD NAV page, the MCDU and PFD display "CHECK APPR SELECTION". This message is a reminder to the pilot that, although an ILS is tuned on RAD NAV page, the available approach guidance modes are APP NAV - FINAL when the APPR pushbutton is pressed in on the FCU.

The FCU APPR pushbutton arms or engages LOC and G/S modes, if :

An ILS approach is entered in the flight plan, or

No approach, or only runway, is entered in the flight plan, and an ILS is manually-tuned on RAD NAV, or

Both RMPs are set to NAV, and an ILS is selected.
AUTOLAND
CHECK that the FMA displays the aircraft capability (CAT2 or CAT3) for the intended ILS approach.
MONITOR the radio automatic callout.

At 350 feet RA :
CHECK that "LAND" is displayed on the FMA.
If LAND is not displayed, do not perform an autoland. A go-around must be performed, if visual references are insufficient.
CHECK ILS course.

Between 50 and 40 feet RA :
CHECK that "FLARE" is displayed on the FMA.

At approximately 30 feet RA :
CHECK that "IDLE" is displayed on the FMA and that autothrust starts to reduce thrust toward IDLE.

At 10 feet, "RETARD" callout comes up :
MOVE the thrust levers to IDLE.
Autothrust disconnects.

At touchdown :
CHECK that "ROLL OUT" appears on the FMA.

At the end of the Rollout
Disengage autopilots :
If an AP is not disengaged at the end of the rollout and the pilot uses the nosewheel steering tiller to taxi the aircraft off the runway, the autopilot will steer the aircraft back to the localizer when the tiller is released.
