AOM VOL2 Flashcards
Spirit Airlines operates three Airbus models:
-A319
-A320
-A321
The aircraft are essentially identical except for:
-fuselage length
and
-engine thrust
The Spirit Airlines A320 Series Operating Manual information is divided into four manuals:
- Aircraft Operating Manual (AOM) Volume 1 2. Aircraft Operating Manual (AOM) Volume 2
- Cockpit Operating Manual (COM)
- Operating Bulletins.
Aircraft Operating Manual (AOM) Volume 1
contains:
System descriptions and operations
Aircraft Operating Manual (AOM) Volume 2
contains:
- INTRODUCTION
- CHECKLIST
- NORMAL PROCEDURES
- FLIGHT CREW TECHNIQUES
- Only AOM Volume 2 is kept on board the aircraft in paper or electronic form.
The Cockpit Operating Manual (COM) contains:
- Limitations
- Memory & Proficiency Items
- LDG DIST PROC
- Fuel Penalty Factors
- Performance
- Abnormal/Emergency Procedures
- Special Operations
- Supplementary Procedures
The Operating Bulletins Binder contains:
-OPERATING BULLETINS (OBs)
And
-OPERATIONS ENGINEERING BULLETINS (OEBs)
OPERATING BULLETINS (OBs):
Issued by Spirit Airlines to provide:
- Necessary operating information more rapidly than possible with the regular manual revision method.
- Background, explanatory, or educational material when it would help ensure proper understanding of the aircraft systems and procedures.
- essentially a temporary revision for a Pilot’s manual
OPERATIONS ENGINEERING BULLETINS (OEBs)
Issued by Airbus
-Rapidly inform operators of any deviations from initial design objectives that have a significant operational impact on the safe operation of the aircraft.
-Operators with technical information and temporary
operational procedures that address these deviations.
- If the OEB conditions are applicable, or are encountered, the Flight Crew must apply the operational procedure(s) in the OEB.
The Flight Crew must use headsets from:
Engine start to 18,000’, and on the descent from 18,000’ until the aircraft is parked at the gate.
The PF will use the “ON” or “OFF” callout when engaging or disengaging the following:
- AP
- FD
- A/THR; or
- Flight Path Vector (bird)
Speeds displayed on the PFD are computed by
Flight Augmentation Computer (FAC)
- according to the FMS weight data
- aerodynamic data
VS: Stalling speed
Not displayed.
Because aircraft of the A320 family have a low-speed protection feature in normal law (alpha max) that the Flight Crew cannot override.
VLS: Lowest Selectable Speed
- computed by the FAC
- top of amber hook along the airspeed scale
- minimum speed in normal operations in smooth air or during a descent
- selected speed/Mach target can be set beyond VLS or VMAX, but when autothrust is active, the guidance limits the speed to VLS or VMAX
- Above 20,000 ft, VLS is corrected for Mach effect to maintain a buffet margin of 0.2 g
- equal to VREF of the selected landing configuration
F: “F Speed.”
- Minimum speed at which the flaps may be retracted at takeoff
- In approach, used as a target speed for autothrust in managed speed
S: “S Speed.”
- Minimum speed at which the slats may be retracted at takeoff
- In approach, used as a target speed for autothrust in managed speed
O: Green Dot speed.
- Engine-out operating speed in clean configuration
- (Best lift-to-drag ratio speed)
- Also corresponds to the engine inoperative final takeoff speed
- Should not be used as the minimum speed above 25,000’
- displayed in CONF 0 only
Protection Speeds:
- Vα PROT
- Vα MAX
- VsW
-computed by the FAC, based on aerodynamic data
-only used for display on the PFD, and not for
flight control protection
(the activation of the protections is computed by the ELAC).
Vα PROT:
Angle of attack protection speed.
- angle of attack at which the angle of attack protection becomes active.
- top of a black and amber strip along the PFD speed scale, in normal law
Vα MAX
Maximum angle of attack speed.
-maximum angle of attack that may be reached in
normal law.
-top of a red strip along the PFD speed scale, in
normal law.
VsW
Stall warning speed.
-red and black strip along the speed scale when the flight control normal law is inoperative.
VMAX
- bottom of a red and black strip along the speed scale.
- Determined by the FAC according to the aircraft configuration.
- Is equal to VMO (or speed corresponding to MMO), VLE or VFE.
Va
Maximum design maneuvering speed. This corresponds to the maximum structural speed permitted for full control deflection, if alternate
or direct law is active
VFE NEXT
- Maximum speed for the next (further extended) flap lever position.
- The VFE NEXT symbol is an amber “=” sign on the PFD airspeed scale.
- It appears when the aircraft altitude is below 15,000’ or 20,000’, depending on the FAC standard
V1
- The maximum speed in the takeoff at which the Pilot must take the first action to stop the airplane within the accelerate-stop distance.
- V1 also means the minimum speed in the takeoff, following the failure of one engine, at which the Pilot can continue the takeoff and achieve the required height above the takeoff surface within the takeoff distance.
- Represented by a blue “1” on the airspeed scale (or a blue number when it is off the airspeed scale).
Vr
- The speed at which the Pilot rotates in order to reach V2 at an altitude of 35 ft at the latest after an engine failure
- Represented by a blue circle on the speed scale.
V2
- Takeoff safety speed that the aircraft attains at the latest at an altitude of 35 ft with one engine failed, and maintains during the second segment of the takeoff.
- Represented by the magenta triangle on the speed scale (or a magenta number when it is off the airspeed scale)
Vref
- Reference speed used for normal final approach.
- top of Vls hook in landing configuration
Vapp
- Final approach speed
- Vapp = Vls + wind correction
- Calculated by the FMGCs.
- The Flight Crew may modify VAPP through the MCDU.
Vapp TARGET
- Represented by a magenta triangle.
- Calculated by the FMGCs.
- VAPP TARGET = GS mini + actual headwind (measured by ADIRS).
- Takes advantage of aircraft inertia when the wind conditions vary during the approach
Rudder Usage
- Manufacturers strongly recommend that the rudder not be used in a stall or unusual attitude recovery
- A rudder input is never the preferred initial response for events such as any type of turbulence encounter, windshear, or to reduce bank angle preceding an imminent stall recovery.
Responsibility for ANTI ICE and IGN in Flight
-PF is responsible for selecting or calling for ENG ANTI ICE, WING ANTI ICE, and/or IGN when required by the present conditions
-PM is responsible for cross-checking ENG ANTI ICE, WING ANTI ICE, and/or IGN at certain procedural times. The PM should also remain
aware of conditions that require these systems to be on
Transit Stops
-when the last checklist performed by the crew was the Parking Checklist, and the Flight Crew is continuing with the same aircraft
-applies only to the following sections of the flight preparation: • Aircraft Acceptance • Preliminary Cockpit Preparation • PF Cockpit Preparation • PM Cockpit Preparation
If a gate return is necessary, perform:
After Landing Normal Procedure, including the After Landing Checklist.
If it is necessary to shut down engines to save fuel during a ground delay after departure from the gate refer to the
Engine Shutdown During Ground Delay Procedure in AOM 2.

DIFSRIPP flight number
Enter the FLT NBR as shown on the flight paperwork and drop any preceding zeros for the flight number itself.
For example, if the flight paperwork shows NKS0714, enter NKS714.
Re-enter winds and temps when
at waypoints where a large difference is expected (greater than 30 kts or 30° for wind; 5° for temperature)
If weather is below landing minimums at the departure airport, in the SEC build
a flight plan to the takeoff alternate airport
DIFSRIPP FINAL fuel
- Domestic flight plan = /45, or
- International flight plan = actual number of CONT (10%) +
FINAL RESERVE (e.g., 8.6).
V1 Brief
Prior to V1:
• It will be my decision to reject.
• I will bring the aircraft to a stop, put the parking brake ON, and call for “Flight Attendant
Stations.”
• Analyze the situation and call for ECAM actions and/or Emergency Evacuation Checklist, if required.
After V1:
We will continue.
• If we have an engine fire or failure:
- The EO SID is ___ (Brief the EO SID, acceleration altitude, and activation of FMS SEC F-PLN, if appropriate.)
- We will plan to land at ___ (Brief return or no return to origin airport considering weight, weather, landing minimums, and if there is a
takeoff alternate.)
- If it is anything else, we will treat it as an in-flight emergency.
- If all is normal, we will continue with the assigned SID.
FUEL QUANTITY CHECK
- Verify ECAM FOB: dispatch release TOTAL RAMP FOB = ECAM FOB within +/- 500 lbs.
- Ensure sufficient fuel aboard prior to pushback (RQD AT TO + TAXI OUT).
- Verify any fuel imbalance is within COM Limitations.
Pushback and taxi without performance and weight & balance data
authorized provided the crew considers the planned GTOW and verifies that the Aircraft Load Sheet and Zone Report are reasonable.
**set flaps to 1+F
“SHIP’S PAPERS ON BOARD”
- international flights only
- verify international documents binder on board
If the ECAM does not display the N WHEEL
STEERG DISC memo, but the ground crew
confirms that the tow pin is in the towing position,
the Flight Crew should not start the engine during pushback. This is to avoid possible nose landing gear damage upon yellow hydraulic pressurization.
To dispatch the aircraft in such a case, refer to the
MEL
If starting engines before pushback or if no pushback is required,
check that the PRK BRK handle is ON, and check the BRAKE PRESS indicator.
If during engine start with the parking brake ON and the aircraft starts to move due to a parking brake failure, immediately
turn the PRK BRK handle to OFF to restore braking by pedals.
GROSS WEIGHT COMPARISON
- Takeoff data calculated GTOW
- Dispatch release ETOW
- MCDU INIT B page TOW
- ECAM GW (after one engine is started)
An amended dispatch release is required if the actual takeoff gross weight is greater than
planned takeoff weight (Dispatch release
ETOW) plus 2000 lbs.
An amended dispatch release is not required
if the actual takeoff gross weight is less than planned takeoff weight
Takeoff at reduced thrust is not permitted:
- On contaminated runways
- For known windshear conditions
- When a Special Departure Procedure specifies
full thrust for takeoff (AeroData requirement) - When a deferred maintenance item per the
MEL requires full thrust for takeoff - When the flex temp is within 10C of actual
OAT.
Takeoff is prohibited on runways where the contaminant is determined to exceed
Level 3
Chart in AOM VOL2 under ACARS preflight section
After receiving the Aircraft Zone Report, ensure the numbers for
“Total checked in” and “On board” match.
In the event the numbers do not match,return the Aircraft Zone Report to the Gate GSA and request a new Aircraft Zone Report.
If the new report provided by the Gate GSA still does not have matching counts, the Captain will request a passenger headcount from the Flight Attendants
for non-standard loading, such as a ferry flight, test flight, or unusual cabin loading, use
AOC LOADSHEET page 2/2
• CATERING: In the event that catering carts are empty, selecting 1L will account for this
• TRPD CTR FUEL: Trapped Center Tank Fuel.
- If the aircraft is to be flown with fuel trapped in the center tank, entering a fuel value in pounds will account for fuel that cannot be used in the center tank.
• EXTRA: Enter a weight in the extra field of the respective zone if there is cargo in the cabin.
- For example, if a passenger is transporting a large musical instrument in the cabin, enter the weight of the instrument in the extra field for the zone in which the instrument is being transported.
If performance and weight and balance data is obtained via ACARS after an engine is started,
the ZFW/ZFWCG will not automatically update.
The ZFW/ZFWCG must be manually corrected on the FUEL PRED page.
If there is a calculation CAUTION or ERROR message
• In the case of a CAUTION or an ERROR condition (not related to fuel on board) where crew entries are correct:
a. Recheck the .Z Report to ensure that it is for the correct date, flight number, and city pair.
b. If all of these are correct ask the Lead Flight Attendant to give a souls on board count. This count should be a simple count with out the complicity of infants and children being separated out.
c. In the event of an ERROR condition, call dispatch with new passenger count and together determine if this was the reason for
the lockout. Dispatch will then reset the system for the Pilot.
- A CAUTION condition allows the weight and balance calculation to continue, but advises the crew that an allowable limit may have been exceeded, and entries should be reviewed for accuracy.
- An ERROR condition stops the W&B calculation and warns the crew that a preset limit has been exceeded.
Takeoff performance data is valid only if the following conditions are met:
- If there is a tailwind component, takeoff performance data must indicate tailwind data.
- Actual QNH is no less than takeoff data QNH minus 0.10”.
- Actual OAT is no less than takeoff data OAT minus 10°C.
- Actual takeoff weight is less than or equal to MTOW.
- The specified flap setting must be used.
- If PACKS OFF is required, bleeds/packs must be appropriately set.
FLEX Takeoff with High OAT
when the OAT is very close to the Maximum Flex Temperature entered in the MCDU.
EPR/N1 discrepancy may result where one engine’s FADEC goes to FLX while the other goes to MCT
To avoid this issue, it is recommended that, when the FLEX temperature and the OAT are within 10°C of each other, a TOGA takeoff should be used.
AeroData Takeoff Weight Variance
- A 500 pound variance (or buffer) is added between the ACARS GTOW and MTOW
- The variance will always ensure the aircraft is under the MTOW in the event that all of the planned taxi fuel is not used (i.e., shorter than expected taxi)
- If actual conditions require greater performance, the 500 pound variance will automatically be reduced in order maximize performance.
(“VAR RDCD TO XXX LB”) will be displayed on the
applicable runway TAKEOFF DATA
Engine 1 is normally used because it pressurizes
the green hydraulic system (normal braking)
Single-engine taxi using Engine 2 is authorized only if
required (e.g. if necessary to reposition after Engine Start with External Pneumatic
Power at the gate and before Crossbleed Engine Start).
Spirit Airlines engine warm-up policy is:
Shutdown for ≥ 2 hrs
5 min before high power
Shutdown for < 2 hrs
3 min before takeoff
When to manually abort an automatic start
- Tail Pipe Fire
2. Loss of both ECAM DUs
TAIL PIPE FIRE:
- Shut down the engine (MASTER OFF).
- Do NOT press the ENG FIRE pushbutton.
- Accomplishthe COM Abnormal/Emergency Procedures “Engine Tailpipe Fire” procedure.
LOSS OF BOTH ECAM DUs duration eng start
• Shut down the engine (MASTER OFF).
• perform a 30 second dry crank by accomplishing COM Supplementary
Procedures “Dry Crank”
PW1100G) If, during the engine start, the ground crew reports a leak from
the engine
abort the engine start sequence. Maintenance action is due before the flight, contact MOC.
When COOLING is displayed on the E/WD
NEO FADEC commanded an automatic dry cranking (engine cooling)
Amber crosses (XX) are displayed on N1 and N2 until they
respectively reach approximately 4.5% and 3.5% during engine start.
DUAL COOLING pb-sw (NEOs)
- The dual cooling function becomes available when the required cooling times of both engines are displayed.
- if dual cooling is required, wait until the indication COOLING is displayed for both engines before setting the DUAL COOLING pb-sw to ON.
Setting the DUAL COOLING pb-sw to ON enables to arm the dual cooling function: When the ENG MASTER lever is set to ON, the FADEC
commands an automatic dry cranking on both engines simultaneously (if cooling is required).
This enhances the overall time to start the engines when cooling is required.
When this function is armed, the memo DUAL COOLING is displayed on the E/WD.
Start valve closes
V2500
Slightly above 43% N2
PW1100G
At approximately 55% N2
If an automatic start on the ground is not successful, the Flight Crew must
- use the ECAM and avoid instinctively selecting the ENG MASTER switch to OFF.
- This would interrupt the FADEC protective actions (e.g., cranking after hot start).
A PTU FAULT is triggered if the last engine is started
within 40 seconds following the end of cargo doors operation.
If ENG ANTI-ICE is selected ON and the valve(s) do not open (FAULT light(s) remain on),
increase the N2 of the associated engine by about 5%. When the valves are open, retard the thrust lever(s) to idle.
FLT INSTRUMENTS . . . . . . . . . . . . . . . . CHECK
Check the following on the PFD:
- V1 and V2 (if entered) display correctly.
- FMA indicates both FD selected ON (1FD2), and other FMA indications are appropriate.
- Selected altitude.
- Preset heading, only if required.
- Flight instruments indicate appropriately and there are no unexpected red indications.
After rudder trim reset, the Flight Crew may observe an indication of up to
0.3° (L or R) in the RUD TRIM position indication.
When to delay after start flap extension:
- taxiing in icing conditions with rain, slush, or snow
- takeoff performance data is not yet available
Authorized takeoff FLAPS settings
- CONF 1 + F
- 2
- 3
During taxi, control may be temporarily
transferred to the First Officer for
only as long as is operationally necessary
The 4 major procedural events that occur during taxi:
- Mini Brief
- Engine 2 Start and After Start Checklist (if single-engine taxi)
- ECAM Status check and Flight Control Check
- Before Takeoff Normal Procedures
Max thrust during taxi
Do not exceed 40% N1 during single-engine taxi
If an arc is displayed above the brake temperature on the WHEEL SD page,
set the brake fans on, if installed.
If the aircraft has been parked in wet conditions for a long period, the first brake application
at low speed is less effective.
During engine start, a slight jerk forward may occur if
brakes are applied while the aircraft is moving.
“FLIGHT CONTROL CHECK”
- After both engines are operating AND before arming the autobrake
- The aircraft should be moving in a straight line or stopped
- It is essential that the CA remains head-up throughout the
procedure.
The purpose of the Mini Brief is to
- refresh Crew Members’ memory of critical information for the takeoff
- to ensure that this information is properly shown on cockpit displays.
To facilitate the Mini Brief, it is recommended that the crew display
- F-PLN page on the PM side
- PERF TAKEOFF on the PF side
If Runway or Takeoff Data Changes after the Mini Brief was already accomplished
a new Mini Brief must be conducted.
Before start ENG INDICATIONS
- Do not turn the ENG MASTER switch ON before all amber messages and crosses (except on N1 and N2) have disappeared
- Wait for bleed pressure to be available.
Use to set takeoff PITCH TRIM
GTOW/CG
-Do not confuse this with ZFW CG
When both engines are shut down what’s erased from the FMGC
-ZFW/ZFWCG
and
-BLOCK fuel
For takeoff, it is recommended that the crew display the on MCDU
- PF……… PERF TAKE OFF
- PM…….. F-PLN
In mountainous areas, the use of TERR ON ND is
mandatory (if operable).
If it is necessary to monitor both radar and terrain,
- PF………..RADAR
- PM……….TERR ON ND
Before entering or crossing a runway, both Crew Members must check that the runway and approach path is clear of traffic,
-visually
and
-using TCAS display on ND
Maximum brake temperature for takeoff
-300°C.
-150°C if brake fans running
(Brake fans should not be used during takeoff, in order to avoid Foreign Object Damage to fans and brakes)
Use of APU bleed is not authorized during takeoff if
wing anti-ice is to be used
When MULTISCAN selector is set to AUTO and when flying below FL 200
Gain must be manually set to +4
Before takeoff responding FLEX/TOGA
- For flex: “temp SET” (“45 SET”)
- For toga: “TOGA SET”
Check aircraft approaching correct takeoff runway using all available visual cues, including:
- Signage and markings
- Heading indicator
Setting T/O thrust
If the crosswind is at or below 20 KT and there is no tailwind
Progressively adjust engine thrust in two steps:
1- From idle to about 50% N1 (1.05 EPR V2500)
2- From both engines at similar N1 to takeoff thrust
Apply half forward stick until the airspeed reaches 80 KT. Release the stick gradually to reach neutral at 100 KT.
Setting T/O thrust
In case of tailwind or if the crosswind is greater than 20 KT
Set 70% N1 (PW1100G) or 1.05 EPR (V2500) on both engines then increase thrust progressively to reach takeoff thrust at 40KT groundspeed
Apply full forward stick up to 80 KT.
Release the stick gradually to reach neutral at 100 KT.
keep-out zone
(V2500)
The FADEC is designed to avoid steady-state operation inside a N1 range between 60% and 74% due to fan flutter phenomenon
Can result in discontinuous EPR increase during thrust setting
The connection between nosewheel
steering and the rudder pedals is removed at
130 kts (wheel speed)
T/O ROTATION
15° THEN SRS (12.5° if one engine is failed)
initiate the rotation to achieve a continuous rotation with a rate of about 3° per second
If a tailstrike occurs,
avoid flying at an altitude requiring a pressurized cabin, and return to the originating airport for damage assessment. Refer to COM Abnormal/ Emergency Procedures Tailstrike
When does NAV or RWY TRK automatically engage?
30ft
Turns after takeoff
In order to comply with our runway analysis (provided by AeroData), the following restrictions apply:
No turns shall be commenced below 1,000’ above field elevation (AFE) when takeoff weather is less than a 1,000’ ceiling and/or less
than 3 SM/5 KM visibility unless a Special Departure Procedure prescribes otherwise or the assigned instrument departure procedure specifically requires a turn before reaching 1,000’ AGL.
During all other weather conditions, normally, turns after takeoff should not be made below an altitude of 400’ above the departure end
of the runway except when necessary in the interest of safety or to conform to established departure and noise abatement procedures.
Thrust reduction altitude
- normally corresponds to 1000 ft AGL
- FD BAR (10°) then,
- Check the target speed change from V2 + 10 to the first CLB speed (either preselected or managed)
(SRS modes reverts to CILMB at ACCELERATION ALT)
Automatic flap retraction speed
210 KT
WING ANTI ICE during takeoff
WING ANTI ICE cannot be included in takeoff performance calculations.
For this reason, WING ANTI ICE may be used after the
flaps/slats are fully retracted.
PACKS OFF for takeoff
- Select PACK 1 on after CLB thrust reduction.
- Select PACK 2 at least 10 s after PACK 1 is selected on, for passenger comfort. (or after flap retraction)
Note: - Selecting pack on before reducing takeoff thrust would result in an EGT increase.
- If packs are not switched on after the takeoff phase,an ECAM caution will be triggered.
When does the CRUISE SD page replaces the ENG SD page.
Flaps to 0
No Flight Director Takeoff
Procedure located in AOM VOL 2
Failure of Both FDs After the Start of Takeoff
- The FD bars disappear.
- The FCU window displays the target speed, which synchronizes on V2, or the current speed (if it is higher).
- The autothrust remains armed.
- At thrust reduction altitude, LVR CLB flashes. When the Pilot sets the thrust levers to the CLB detent, the autothrust becomes active in selected SPD mode (no FDs selected).
- At acceleration altitude the target speed does not change, since it is selected.
Takeoff With No V2 Entry
This is not an authorized normal procedure
- (SRS) will not engage for takeoff
- 5 seconds after lift off, V/S mode will engage. When V/S engages, the current airspeed becomes the FCU target speed.
To regain a normal speed target, the Pilot must:
• SELECT the appropriate climb speed on the FCU and PULL out the knob.
At acceleration altitude:
• PUSH the A/THR pb on the FCU.
• SET the thrust levers to CL detent.
• PUSH in the SPD selector knob to get a managed speed target.
Should an FMGS failure occur, how can crew determine the OPT FL and REC MAX?
COM Performance charts
MAX REC FL
gives the aircraft at least a 0.3 g buffet margin
“CHECK GW” Message
If the MCDU “CHECK GW” scratchpad message appears,
refer to COM Supplementary Procedures “Auto Flight” “FMGS Reset and Other Abnormal Procedures” “Other Abnormal Procedures.”
Expedite Climb
- not recommended above FL 250
- the target speed is now Green Dot
Immediate Return to Origin Airport
• ACTIVATE the SEC F-PLN
Or
• PERFORM a lateral revision at TO waypoint
