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).
