PREFACE
Applicable to: ALL
The ABNORMAL OPERATIONS chapter highlights techniques that will be used in some abnormal and emergency operations. Some of the procedures discussed in this chapter are the result of double
or triple failures. Whilst it is very unlikely that any of these failures will be encountered, it is useful to have a background understanding of the effect that they have on the handling and management of the aircraft. In all cases, the ECAM should be handled as described in FCTM (Refer to OP-040 PURPOSE OF THE ECAM).
LANDING DISTANCE PROCEDURE
Applicable to: ALL
Should a failure occur with "LANDING DISTANCE PROC....APPLY" message displayed on the ECAM STATUS page, the crew will enter the LDG CONF/APP SPD/LDG DIST/ CORRECTIONS FOLLOWING FAILURES table in QRH abnormal procedures and read:
? The flap lever position for landing
? Delta VREF if required for VAPP determination
? The landing distance factor for landing distance calculation
VAPP DETERMINATION
Applicable to: ALL
1 BACKGROUND
Some failures affect the approach speed.
? Some failures (typically slat or flap failure) increase the VLS. In this case, the VLS displayed on the PFD (if available) takes into account the actual configuration.
? In some others failures, it is required to fly at speed higher than VLS to improve the handling characteristics of the aircraft. This speed increment is to be added to the VLS displayed on the PFD when the landing configuration is reached.
In order to prepare the approach and landing, the crew needs to calculate the VAPP in advance.
The appropriate VLS is not necessarily available at that time on the PFD, because the landing configuration is not yet established.
VAPP = VREF see(1) + ΔVREF see(2) + APPRoach CORrection see(3)
(1) VREF from:
‐ MCDU PERF APPR page provided MCDU F-PLN is updated and sequenced, or
‐ VAPP Calculation in the case of an ABNORMAL / EMERGENCY Configuration (QRH part 2 - ABNORMAL PROCEDURES).
