1 GO AROUND 1.GO AROUND INITIATION 3.THRUST REDUCTION/ACCELERATION ALTITUDE 5.DIVERSION 2.LATERAL GUIDANCE 4.HOLD (missed approach) A320 - Version 05

2 1. GO AROUND INITIATION Decision THRUST LEVERS. TOGA ANNOUNCE. GO AROUNDS FLAPS FLAPS RETRACT ONE STEP FMA ORDER.. GEAR UP When positive climb ANNOUNCE. POSITIVE CLIMB L/G....UP ANNOUNCE.. GEAR UP - FLAPS GRND SPLR. DISARM EXTERIOR LIGHTS....SET TOGA GO AROUND PHASE Missed approach becomes the ACTIVE F-PLN and the previously flown approach is strung back into the F-PLN

3 2. LATERAL GUIDANCE NAV or HDG SELECT FMA The GA TRK mode guides the A/C on the memorized track at the time of TOGA selection Push HDG Knob: NAV mode engages (Guidance for published missed approach)... Or Pull HDG Knob and set heading as cleared by ATC...

4 3. THRUST REDUCTION/ACCELERATION ALTITUDE When LVR CLB flashing at thrust reduction/acceleration altitude THRUST LEVERS.CL FMA At F speed with positive speed trend : FLAPS 1 At S speed with positive speed trend : FLAPS 0 AFTER TAKEOFF / CLIMB C/L down to the line F S

5 4. HOLD CONTINUE ON STANDARD MISSED APPROACH PROCEDURE AND ENTER HOLDING PATTERN 3 types of HOLD can be performed Observe on ND the pattern entry type : LATERAL REV at HOLD : Inbound Ex: direct entry FMGS HOLD parameters HOLD EXIT LIMIT information (When established in Holding pattern)

6 5. DIVERSION Divert to another airport : Lat Rev at TO WPT.ENABLE ALTN When cleared to a WPT: IMM EXIT.. PRESS DIR TO PERFORM If necessary, at transition altitude : FMA BARO REF: STD AFTER TAKEOFF / CLIMB C/L below the line CLIMB PHASE ENABLE <- ALTN 1st CLB SPD PROG PAGE DEFAULT CRZ FL = FL220 FL310 if ALTN is at less than 200 NM if ALTN is at more than 200 NM

7 GO AROUND IF : 1.ACTION MONITORING CROSS CHECKING 2.LATERAL GUIDANCE 3.THRUST REDUCTION Approach is not properly stabilized Doubt about situation awareness Malfunction ATC changes the final approach clearance Adequate visual cues not obtained at MDA or DH Any GPWS/TCAS or Windshear alert occurs 4.ACCELERATION 5.FLIGHT CONTINUATION THEN engage GO AROUND procedure LR - Version 02

8 FLIGHT PHASE SWITCHING CONDITIONS Preflight Take Off Climb Cruise Des Approach Go Around or Done FLIGHT PHASES OPTIMUM SPEED PROFILE SWITCHING CONDITIONS TO NEXT PHASE PREFLIGHT / SRS take off mode engaged and N1> 85% (EPR >= 1.25) or Ground Speed > 90 kt TAKE OFF V2 (V2 + 10) At acceleration altitude or by engagement of another vertical mode CLIMB ECON CLB SPD / MACH Reaching cruise FL CRUISE ECON CRZ MACH At descent initiation (if distance to DEST < 200 NM and no step descent) DESCENT APPROACH GO AROUND ECON DES MACH / SPD Vapp (GS Min) Vapp or current SPD whichever is greater. Green Dot at ACC ALT - Over flying (DECEL) pseudo waypoint with NAV (or LOC*/LOC) mode engaged and altitude < 7200 ft AGL - Manual activation of the approach phase. 1. To Go Around : when thrust levers at TO.GA detent or 2. To Done: 30 seconds after landing or 3. To Climb: when inserting a new CRZ FL 1. To Approach : Manual activation of the approach phase or 2. To Climb: Above acceleration altitude by - Selecting ALTN or - inserting NEW DEST and CRZ FL DONE / To preflight when INIT or PERF key depressed

9 HOLD 4. HOLD CONTINUE ON STANDARD MISSED APPROACH PROCEDURE AND ENTER HOLDING PATTERN DATABASE HOLD AT (Database stored HOLD) Three types of HOLD can be performed COMPUTED HOLD AT (Standard HOLD computed by FMGS) Check the accordance between FMGS HOLD parameters HOLD AT and published (Manual data : entry) Observe on ND Reversions REVERT TO COMPUTED The speedrevert TO DATABASE change symbol WPT INB CRS TURN R TIME/DIST. /. For HOLD exit limit information perform a Lateral Revision at WPT : The pattern entry type Ex: direct entry Inbound LAST EXIT UTC FUEL

10 DIVERSION : 3 POSSIBILITIES The ALTN has been prepared CLIMB PHASE Lat Rev at TO WPT.ENABLE ALTN The SEC F-PLN has been prepared to a diversion airfield SEC F-PLN...ACTIVATE CLIMB PHASE Nothing has been prepared! SPD 250 kt + OP CLB... SELECT NEW DEST + CRZ FL.INSERT CLIMB PHASE F-PLN..FINALIZE
