The CONF FULL VAPP displayed in the MCDU may be modified,depending on pin program to VLS + 9 + wind from the present logic of VLS + 5 + wind. The objective is to keep, for normal landings, the current VAPP despite the lower VLS (LIP). There is no change in the current philosophy concerning the use and modifications of VAPP on the MCDU for all manual landings and Autolands.
For landing on short runways the MCDU VAPP must be overwritten by the crew to select a lower approach speed (limited to VLS).
When using reduced approach speeds, crews should be aware of the reduced margins relative to a landing tailstrike. Autoland is not allowed with the reduced approach speed.
In failure cases where an approach speed increment is specified (in the QRH), an extra 5 kt should be added in order to keep the same approach speed values for A321-100 and -200.

06 - COMPLETION STANDARDS
.  
Awareness of landing limitations.

.  
Use of correct landing technique and execution of standard landing.

.  
Employs correct technique for use of reverse thrust and manual braking or properly monitors autobrake deceleration.

.  
Avoids significant deviation from runway centerline.

07 - COMMON ERRORS
.  
Overcontrolling in pitch or roll.

.  
Flaring too high.

.  
Failure to flare or flaring too late.

.  
Not selecting idle thrust for landing.

.  
Delayed selection of reverse thrust.

.  
Failure to monitor SD WHEEL page and/or AUTO/BRK panel during deceleration.

.  
Maximum reverse thrust maintained below 70 kt or reverse stowed before taxi speed.

.  
Differential braking used during roll out.

REV 21  MAY 98 

The go-around mode is engaged by setting the thrust levers to the TOGA gate, provided at least CONF 1 is selected. Monitor FMA annunciations for correct operation.
If going around from a visual approach (FDs off), set thrust levers to TOGA, rotate to 15 nose up, and maintain VAPP or above. The restoration of the FDs may not give accurate pitch information as the FDs return in basic modes (HDG V/S).
Lateral navigation will stay in GA TRACK mode until the heading selector knob is pulled or pushed to engage HDG or NAV mode. The go-around can be flown with two autopilots engaged, but when another lateral or vertical mode is selected, one autopilot drops out. Speed target will be green dot when GA ACCEL ALT is reached, as the design assumes another approach will be flown, following the go-around.
