FLIGHT PHASES
4 GO-AROUND
8.2. Standard GO-AROUND
Go-around initiation
Example shows a go-around after a dual ILS approach. Same logic
applies for other approaches.
PFD:
−
FMA displays: MAN TOGA / SRS / GA TRK / ATHR blue,
−
Target speed is SRS.
SRS mode provides managed speed guidance to existing IAS at GA
initiation (or VAPP if existing IAS<VAPP) until acceleration altitude,
then to green dot speed or as selected on FCU.
GA TRK mode provides lateral guidance to maintain the track existing
at GA initiation, memorized by FMGC.
ND:
Missed approach becomes ACTIVE F-PLN, changing from blue to
dashed green on ND.
MCDU:
PERF APPR changes to PERF GO AROUND, showing:
−
F, S, green dot speeds,
−
THR RED and ACC altitudes for the go-around,
−
ENG OUT ACC altitude,
−
ACTIVATE APPR PHASE and NEXT PHASE prompts.
F-PLN page (A or B) shows WPTs of missed approach routing in green
instead of blue, followed by a F-PLN DISCONTINUITY.
The previous APPR procedure is retained, following the F-PLN
DISCONTINUITY, which can be viewed by scrolling up.
The DEST RWY remains on bottom line; the DIST to destination shown
is total distance to landing, via missed approach and the retained
approach, e.g. PPOS to 3000’, direct to CF27R, plus approach.
Note:
In SRS mode, vertical guidance is not managed. The initial altitude
constraint of the missed approach procedure must be set on FCU after
passing FAF on the approach.
If a constraint exists: "CSTR DEL UP TO XXXX" s-pad msg (white) is
triggered.
