  A320 INSTRUCTOR SUPPORT NORMAL OPERATION 1 — AIRCRAFT DOCUMENTATION The MMEL and MEL The MMEL is the Master Minimum Equipment List published by the A/C manufacturer and certified. It allows an aircraft to be dispatched with some items of equipment or some functions inoperative — provided some specific limitations or procedures, or maintenance actions are carried out — in order to avoid delays or cancellations.

• Page 12
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION General Operational Rules for the MEL: 1. The MEL theoretically applies to Revenue flights (out of base, the A/C should be clean of failures, or hold items must be mentioned in the technical log and approved). 2.

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION FMGS programming The normal sequence of FMS programming consists in filling up Navigation Data and then Performance data: Status page Init A page F.PNL A page Navigation Data Sec FPLN Rad Nav Page Init B page Performance Data Perf pages This sequence of data entry is the most practical;…
• Page 15
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION NOTE: It often happens that the loadsheet is brought very late to the crew – However in many cases the crew knows what the expected ZFW is, how much fuel is required for the sector. Thus the crew know the expected TOW which allows then to prepare the expected T/O speeds and FLX TEMP.
• Page 16
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION The climb performance itself: For example, if a climb gradient of 5% is required (e.g. due to obstacles) in the previous take-off conditions, the MTOW is reduced from 257.6 t down to 256.2 t when CG varies from 26% to full forward CG.
• Page 17
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION • Maneuvering criteria — Maneuver point Depending upon the CG location, a given deflection of the elevator causes a more or less sharp aircraft maneuver. In other words, the CG has a direct influence on the maneuverability of the aircraft. If a very small deflection of the elevator causes «a lot of g», the efficiency of the elevator is very high;…
• Page 18
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION • Structural Considerations The CG cannot be too much forward due to Nose Gear structural limits; it cannot be too much AFT due to wing and main landing gear strut limit. • Loading Considerations All the previous criterias allow to determine limits which, for example, would favor AFT CG configurations for obvious performance efficiency.

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION PF/PNF task sharing and cockpit preparation sequence and scan The FCOM and QRH detail this essential phase of the flight. A particular geographic scan has been developed in order to maximize the resource involvement in the spirit of ACRM. Accordingly the PF/PNF concept applies from the time the crew arrives at the aircraft till they leave the machine.

• Page 21: Take Off Briefing

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION 3 — TAKE OFF BRIEFING The main objective of the Take off briefing is for the PF to inform the PNF of his intended course of actions during Take off and initial climb, in normal and abnormal situations. It may be completed by specific Captain’s instructions. Any misunderstanding shall be clarified through questions.

• Page 22: Engine Start

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION 4 — ENGINE START The normal engine start procedure is the AUTO START procedure; the MANUAL START procedure is used exceptionally in specific cases. During an AUTO START procedure the FADEC protects the engines against HOT, HUNG START, START STALL …, it detects these phenomena and takes the appropriate action (reducing the fuel flow, or cutting it off, cranking the engine, attempting a new start etc.

• Page 23
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Furthermore, the starter engagement is limited in time and in number of successive attempts: CFM: 4 times 2 mn with 20 sec between each start. IAE: 2 times 2 mn + 1 time 1 mn with 15 sec between each start. This is the reason why the use of the stopwatch is recommended.

• Page 24: Taxi And Braking

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION 5 — TAXI AND BRAKING Before taxiing, check NW STREERG DISC amber MEMO is not displayed on ECAM to confirm NWS is available. During taxi, there are several issues: taxi roll and steering, braking. Taxi roll and steering In order to initiate the taxi roll, the use of minimum thrust is recommended to avoid FOD (N1 40 % max).

• Page 25
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Minimum Turn Radius (assuming symmetrical thrust and no differential braking). The figures are provided for A320-200. The minimum runway width (pavement) required for 180° turns is 30 m (99 ft). The turn application assumes symmetrical thrust and no differential braking. The specific 180° turn procedure is described in A320 FCOM 3.03.10. Nose radius: A319 16.6 m…
• Page 26
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION OVERSTEERING TECHNIQUE For A 321 (longer a/c), it may be necessary to consider oversteering technique, main gear being 20 m behind the pilot. In case of a 180° turn on the runway a specific procedure is provided in SOP. Keep in mind that: You should not let the G/S drop below 8 kts during the maneuver in order to avoid stopping.
• Page 27
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Parking brake particulars: Note that, when the parking brake is ON, pressing on the pedals has no effect on the braking. Consequently if for any reason the aircraft moves forward while parking brake is ON, the parking brake must be released in order to get braking efficiency from the pedals (on latest A320s, a modification provides the availability of pedal braking even if parking brake is ON).

• Page 28: Take Off

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION 6 — TAKE OFF The take off is actually divided into various sequences: Take off initiation and power set: Set the power in 2 steps in case of headwind and crosswind till 20 kts: • bring thrust levers to 50 % N1 (1.05 EPR) position using the thrust lever symbol on the N1 (EPR) gauge.

• Page 29
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Take off roll: Use the rudder pedals to steer the A/C. The NWS will be effective till 130 kts. Don’t use the tiller beyond 20 kts. Avoid using the stick into wind; indeed this increases the natural tendency of the a /c to turn into wind. In case of low visibility take off (RVR down to 125 m) visual cues are the primary means to track the runway center line.

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Tail strike considerations: Refer to FCOM bulletin 22 for briefing about tail strikes: CONDITION TAILSTRIKE PITCH ATTITUDE LANDING GEAR COMPRESSED EXTENDED A319 13.9 ° 15.7 ° A 320 11.7° 13.7° A 321 9.7° 11.4° The recommended flap configuration to provide best tail clearance at take off is CONF 2. It is therefore to be used whenever performance allows, considering furthermore that when CONF 1 + F is chosen, take off close to V2 mini may have to be achieved.
• Page 31
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Other drills in take off: On the EFIS Control panel, select CSTR. If the A/C is TCAS equipped, select ABV (if available). If there is weather, use the radar and set TILT + 4°. If there is terrain around the airport or along SID, set TERR ON ND to ON to allow EGPWS display. If PACKS are set to OFF at take off, select them back ON only once thrust is reduced in order to avoid potential resulting EGT increase.

• Page 32: Climb

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION 7 — CLIMB The transition into CLIMB phase occurs at ACCEL ALT or more precisely when SRS mode disengages; target speed goes to initial climb speed. Climb Speed profile — Speed managed / Speed selected The best climb speed profile is the managed speed profile which takes into account GW, CI, CRZFL, Altitude and Speed constraints.

• Page 33
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Altitude considerations The FMS PROG page provides: The MAX REC ALT which corresponds to 0,3 g buffet margin The OPT ALT which depends upon GW, CI but also FPLN remaining cruising distance, temp, … This information is used among other to rapidly answer to ATC: « can you climb to FL …» for example. NOTE: A CRZ ALT higher than max altitude corresponding to 0,2 g buffet cannot be inserted.
• Page 34
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Other drills: When crossing 10.000 ft, it is a good practice to watch the ECAM MEMO so as to ensure that some drills have not been left behind: e.g. LDG LT OFF / SEAT BELTS OFF (according to flight conditions). It is also time to clear the manually inserted navaids on MCDU NAVAID page, so as to allow full autotuning, to select ARPT on EFIS Ctl panel and COPY ACTIVE into secondary.

• Page 35: Cruise Management

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION 8 — CRUISE MANAGEMENT Reaching the Initial cruise Flight Level: When reaching the Initial cruise Flight Level: → Ensure ALT CRZ on FMA. → Cross check FMS NAV ACCY. → Review ECAM main pages → Set TCAS to ALL (if applicable), or to BELOW if cruise altitude within 2000 ft from FL 390. →…

• Page 36
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION In order to do so, take the computerized FPLN and determine the waypoints where a wind/temp entry is necessary, according to the following rule of thumb (and use of common sense…): • at the first waypoint in cruise, insert wind DIR/VEL, and temperature at the initial CRZ FL. •…
• Page 37
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION In cruise always fly with ALT CRZ mode on the FMA. If the A/C climbs from one CRZ FL to another, the ALT CRZ is automatically updated. If the A/C descends towards a lower CRZ FL, the ALT CRZ is usually updated except if it does so within 200 NM from destination.
• Page 38
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION NOTE: • CI has an effect on OPT FL. • It is absurd to play with CI to get a given Mach Number in cruise. Select the given Mach number on the FCU; the FMS updates all predictions accordingly. •…
• Page 39
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Fuel considerations The fuel consumption of the A/C is directly affected by: the way the A/C is operated: • fly as close as possible to OPT FL (+1000 ft / -4000 ft), As a rule of thumb up to ISA +15: OPT FL ≈…

• Page 42
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION The descent and approach preparation and briefing must be done early enough to get properly prepared and provide the proper information. Typically 80 NM to 60 NM before TOD is a good time. NOTE: If no data is inserted for the approach 200 NM from DEST, ENTER DEST DATA message comes on the MCDU to advise the crew to get prepared for the arrival.

• Page 43: Descent

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION 10 — DESCENT In order to carry out the descent and to reach the Initial Approach Fix (IAF) in good situation, the crew has at its disposal Descent guidance modes and descent monitoring means. The modes and monitoring means are actually linked.

• Page 44
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION • Case a): If the A/C tends to get below path, the current speed decreases towards the lower limit of the speed target range to keep the A/C on path with IDLE thrust. If the speed reaches the lower limit, then SPEED mode engages on the A/THR, to keep the A/C on path at that lower speed.
• Page 45
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION • Suppose the A/C is below path and the pilot is cleared down. He presses DES mode with managed Speed. A/C below path — Path Intercept Prediction The DES mode will guide the A/C on a shallow descent converging towards the descent profile (1000 ft/mn or less depending on the circumstances) with the ATHR on SPEED mode.
• Page 46
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION If, for any reason, the ATC requests a steeper descent while the A/C is in DES mode, on path or below, pull OPEN DES mode, increase speed and use SPD BRK if necessary. But don’t select higher speed, or extend speed brakes with managed DES, because in most cases this will result in thrust increase, the aircraft being guided on the descent path by DES mode.
• Page 47
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION When V/S is used, the A/C is guided to that V/S with SPEED mode on ATHR. In descent V/S is used: • for small step descent, in order to get a smooth guidance with reduced thrust variations and •…
• Page 48
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Various Drills in descent • Before TOD, select destination VOR/DME needle, press CSTR button on EFIS CTL panel, and set TCAS to BELOW. • As a general rule, preferably set PF MCDU on PROG, PNF MCDU on F PLN. •…

• Page 49: Approaches

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION 11 — APPROACHES The approach briefing by instructors needs to be STRUCTURED so that pilots have a good guideline or SKELETON applicable to any type of approach. All approaches shall then be flown similarly. Therefore, the approach briefing notes are structured as follows: General Approach Briefing ILS Approach Standard ILS,…

• Page 50: 11/1 — General Approach Briefing

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION 11/1 — GENERAL APPROACH BRIEFING All approaches are divided into 3 parts: the Initial Approach, from IAF (≅ 15 NM from destination) to the activation of approach phase materialized by the (DECEL) pseudo waypoint, the Intermediate Approach from (DECEL) to FAF and the Final Approach from FAF to landing or minimum.

• Page 51
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Select the BEST FLYING REFERENCE for the approach. The FPV (called BIRD) is best adapted for all types of approaches and is strongly recommended for NPA or VISUAL approaches (BIRD ON). Attitude associated to FD crossbars is still most commonly used to fly ILS approaches (BIRD OFF). ACTIVATE THE APPR PHASE The purpose of this activation is to initialize the deceleration towards VAPP or towards the speed constraint inserted at FAF, whichever applies.
• Page 52
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Intermediate Approach The purpose of the intermediate approach is to bring the aircraft at the proper speed, altitude and configuration at FAF, and to guide the aircraft to the proper final trajectory at FAF. Aircraft deceleration and configuration changes Managed speed is recommended.
• Page 53
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Final Approach Monitor the Final Approach mode engagement: • G/S * or FINAL engagement when required, or select Final descent path FPA reaching FAF, • if the capture or engagement is abnormal, take over manually by selecting the proper FPA. Monitor the Final Approach using raw data: •…
• Page 54
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION • A deceleration below VAPP may occur in following cases: GPWS terrain avoidance maneuver, Collision avoidance maneuver, Windshear escape maneuver. In all those cases, the pilot shall slam all thrust levers to TOGA. NOTE: Be aware that if you move thrust levers up to TOGA, SRS / GA TRK will engage. •…

• Page 55: 11/2 — Ils Approach

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION 11/2 — ILS APPROACH A) Standard ILS approach Decelerated approach is recommended. The following particulars apply for ILS approaches: Initial Approach For CAT I ILS, insert D(A) value into MDA field [or D(H) value into MDH field for QFE equipped a/c] on PERF APPR page, since these are baro referenced.

• Page 56
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION B) Glide Slope Interception from above The problem is actually linked to the following factors: High speed, FCU altitude usually set at G/S INTCPT altitude and G/S mode does not intercept from above. A/C high above G/S — Potential AP / FD Problem In such a case, the reaction of the crew must be rapid to succeed to stabilize the A/C at 1000 ft AGL, VAPP, LDG CONF on G/S.
• Page 57
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION NOTE: If, with high V/S, IAS increases to VFE, the AP/FD will no longer keep the target V/S. The AP/FD will pitch the A/C up to shallow the descent so as to fly a speed lower than VFE. Do not extend Landing gear at too high speed (> 220 kts) in order not to overstress the doors, and to minimize the noise.
• Page 58
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION The BIRD is NOT best adapted to fly GO AROUND. Indeed, the go around is a pitch dynamic maneuver, during which the bird is lagging behind due to the inertia of the aircraft. Hence if GO AROUND is initiated while BIRD is ON, it is then recommended to ask the PNF to set BIRD OFF, in order to fly with the attitude reference and FD bars.

• Page 59: 11/3 — Non Precision Approaches (Npa)

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION 11/3 — NON PRECISION APPROACHES (NPA) The stabilized approach technique is recommended. Reach FAF with CONF FULL and VAPP. The following particulars do apply to NPAs. The overall strategy of NPA completion is to fly it « ILS alike » with the same mental image or representation, and similar procedure.

• Page 60
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Intermediate Approach It is very important to have a correct FPLN in order to ensure a proper Final Approach guidance. Indeed the NAV and APPR NAV modes are always guiding the A/C along the ACTIVE LEG of the FPLN, and the managed VERTICAL mode ensures VDEV = 0, VDEV being computed along the remaining FPLN to destination.
• Page 61
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION In certain cases, the FINAL APPR flies an « IDLE DESCENT Segment » from one ALT CSTR to another, followed by a level segment. This is materialized by a magenta level off symbol on ND followed by a blue start of descent Final approach trajectory — an idle descent segment If during the final approach the message NAV ACCY DNGRADED comes up, immediately refer to raw data: If the check is OK, you may continue.
• Page 62
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION If SELECTED Approach • Overfly FAF, properly identified, and • select TRK = Final APPR CRS, • select FPA = Final APPR path (actually start the final descent 0.3 NM before FAF). Final approach using the bird with AP/FD — TRK/FPA modes Use ATHR and Managed speed.
• Page 63
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION During intermediate approach: use TRK mode to align the aircraft on the localizer. The PNF ND on ARC mode provide valuable information to achieve that goal, provided FMS ACCY is OK or GPS is Primary. In Final approach: use FPA mode to set the aircraft on the final descent path.

• Page 64: 11/4 — Circling Approach

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION 11/4 — CIRCLING APPROACH The circling approach is flown when the tower wind is such that the landing runway is different from the runway fitted with an instrument approach, which is used to descend and approach in order to get visual of the airfield. The instrument approach prior the circling is a stabilized approach flown in CONF3 — L/G Down — F speed, with BIRD ON or OFF, depending upon the approach type.

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Final instrument approach Fly it with CONF3 — L/G GEAR DN — F speed, with the usual technique. Reaching MDA — push TO LEVEL OFF. • If visual, proceed down wind (HDG SEL or TRK SEL). •…

• Page 66: 11/5 — Visual Approach

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION 11/5 — VISUAL APPROACH The visual approach is flown with (FPV) BIRD ON, AP/FDs off, ATHR ON and managed speed. Typical Visual Pattern — Lateral Profile Initial Approach As a help to have a comprehensive display on ND, ND may be set to ROSE NAV to assist the pilot to visualize the circuit from mid-downwind.

• Page 67: Precision Approaches — Cat Ii — Cat Iii

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION 12 — PRECISION APPROACHES — CAT II — CAT III General Consideration • The only Precision Approaches are CAT I, II and III approaches. Since those approaches are flown to very low DHs, with very low RVRs, the guidance of the aircraft on the ILS beam, and the guidance of the aircraft speed must be CONSISTENTLY of HIGH PERFORMANCE and ACCURATE so that the transition to visual conditions (if any) is achieved with the aircraft properly stabilized.

• Page 68
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION • In order to fly a precision approach: — the aircraft equipment and systems required must be available (FCOM 4.05.70), — the airport equipment and installation required must be available and serviceable, — the airport has to be operating in CAT II/III conditions, — the aircrew must be qualified, — the specific wind limitations (30 kts head, 10 kts tail, 20 kts cross), and the maximum altitude limit as per AFM must be applied:…
• Page 69
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Operational Consequences TASK SHARING • The task of each pilot is essential and complementary. The PF supervises the approach (trajectory, attitude, speed) and takes appropriate decisions in case of failure and/or at DH. Since the approach is flown with AP/ATHR ON, the PF must be continuously ready to take over if any AP hardover is experienced, if a major failure occurs and if any doubt arises.
• Page 70
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Some requirements are specific to CATIII with NO DH, because an Autoland is compulsory. These are not necessarily monitored and thus not indicated. • Incorrect ILS CRS (∆ 5° with runway CRS) leads to incorrect autopilot DECRAB. Check ILS CRS at 350 ft.
• Page 71
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION SOME SYSTEM PARTICULARS The FMGS monitors its landing capability. If both APs are engaged, the capability displayed on FMA corresponds to the LOWEST of both APs. There is no capability degradation below 200 ft (alert height), due to the extremly low probability of a second failure within the remaining time.
• Page 72
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Landing / Roll out Although when LAND mode appears on FMA, this ensures that all is set for autoland, it is most recommended that the PNF announces FLARE. The PF should then notice a pitch up reaction of the aircraft. During FLARE, Decrab and Roll out, the PF shall watch outside to assess that the maneuver is OK considering the available visual references or if DH is very low, to achieve the visual references.
• Page 73
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Approach briefing associated to precision approaches before TOD Considering all the specifics of Precision Approaches, the approach briefing will outline additionally to the standard approach briefing: the airport specific requirements, the general task sharing strategy, and exceedance call outs and the general strategy in case of failure (above/below 1000 ft).

• Page 74: Vapp Determination

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION 13 — VAPP DETERMINATION VAPP in Normal Configuration VAPP is defined by the crew to perform the safest approach; it is a function of GW, CONF, WIND, ATHR ON/OFF, ICING, DOWNBURST. VAPP is computed out of VLS (1,23 VS1G) of the landing configuration: 5kts for ATHR VAPP = VLS + ∆…

• Page 75
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION VAPP in Case of Abnormal Configuration (slats / flaps, flight controls etc…). When a slats / flaps abnormal configuration occurs, the PFD displays a correct VLS related to the actual slats / flaps configuration, except if both SFCCs have failed. In some of these abnormal configurations, it is advisable to fly at a minimum speed higher than VLS to improve the handling characteristics of the A/C.
• Page 76
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION The GS mini guidance has 3 major benefits: 1. It allows an efficient management of the thrust in gusts or longitudinal shears. Thrust varies in the right sense but in a smaller range (± 15% N1) in gusty situations which explains why it is recommended in such situations. 2.
• Page 77
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION In case of a tailwind gust, which often follows a head wind gust in a shear, IAS and speed trend arrow go down, as well as the target sped; N1 smoothly decreases – This is what happens in between b) and c).

• Page 79
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION FLARE ITSELF When reaching 50 ft RA, the pitch law is modified to flare mode: indeed, the normal pitch law which provides trajectory stability is not the best adapted for the flare maneuver. The system memorizes the attitude at 50 ft, and that attitude becomes the initial reference for pitch attitude control.
• Page 80
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION PAPI is aligned with a G/S path. As the VASI it provides an aiming point adjacent to the installation, and materializes a constant visual approach path to assist the pilot in the visual part of the approach. ICAO requirements specify that PAPIs should be positioned such that Minimum Eye Height over Threshold (MEHT) gives adequate wheel clearance for aircraft which are regular users.
• Page 81
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION If the A/C comes for landing with wind from the LEFT, and if the pilot wishes the A/C to land with the fuselage aligned with runway center line, he has to apply some rudder to the RIGHT. Thus, if he does not act laterally on the stick, the A/C will turn to the right because of the resulting bank angle and because of the effect of the wind.
• Page 82
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION ! Derotation, roll out and braking • Derotation When the A/C is on ground, pitch and roll laws are basically direct. As a consequence, when the A/C touches down, the pilot has to fly the nose down gently by maintaining a slight aft pressure on the stick to slow down the de-rotation movement.
• Page 83
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION • Braking A proper braking technic will minimize the landing distance. However there are many factors during final approach which affect the landing distance and reduce some of the regulatory margins built in the minimum required distance for landing: factors increasing the TAS at landing: airport elevation 1000 ft, and/or QNH 980 hPa adds 10% to actual landing distance a 10% excess in approach speed, adds some 20% to actual landing distance…
• Page 84
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Thus the braking efficiency depends upon the A/C speed, the load on wheels, the wheel speed (free rolling, skidding or locked wheels), the runway condition but also the brake temperature and wear. The antiskid system maintains the skidding factor close to the point providing maximum friction force; with full pedal braking with anti skid the typical deceleration rate is 10 kts/sec (or .5g).
• Page 85
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION • Overall recommendations for the ground phase: Always Arm the ground spoilers. Use A/Brake on Short, or on Wet & Contaminated runways, if poor visibility or with Autoland. MED is recommended. Selection of A/Brake is left at Captain’s discretion in other cases; more particularly when significant need of wheel brake application is foreseen (brake wear consideration).
• Page 86
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION • Landing distances in QRH The actual landing distance published in FCOM and QRH (4.0) is the certified landing distance demonstrated using manual landing technique, ground spoilers and full pedal braking from touch down to complete A/C stop, but with no reverser.
• Page 87
  A320 INSTRUCTOR SUPPORT NORMAL OPERATION Shutting down the engines — Potential of Tail Pipe Fire When the aircraft taxies back to the gate, the crew must respect a minimum time required on certain engines between landing (use of reverser) and engine shut down.

  A320 INSTRUCTOR SUPPORT NORMAL OPERATION NOTE: Speed, Speed Trend, Attitude, Flight Path angle, Flight Path vector, V/S are good indicators of the situation. NOTE: Refer to chapter 24 for more details. In approach, use ATHR ON with managed speed, to benefit from GS mini guidance. Volcanic Ashes Volcanic ashes or dust are composed of very ABRASIVE particles which may cause engine surge, accumulation of volcanic material on turbine vanes and cause severe damage to aircraft surfaces most exposed to airflow.
