Sharklets improve take-off performance
• If facing obstacles or climb limitations, Sharklets will increase take-off weight by: • Improving second segment performance • Clearing more obstacles
Improved operational efficiency around the world
Better take-off
capability

Operational considerations
Entry into service of A320 Sharklets: Effects on Flight Operations and Performance Documentation
Introduction of new imbalance limitations for takeoff • Fuel imbalance limitations in flight and at landing unchanged
CAT II and CAT III Automatic Apprs and Ldgs • Automatic rollout crosswind limitations: 15kt (already on A318/319/321)
Flight control law enhanced • In case of yaw damper loss, when the landing gear is extended, the yaw
damper remains in alternate law (previously: switched to direct law)
CDL Static discharger • Only one static discharger may be missing per Sharklet if the hole is
covered with high speed tape.

Operational considerations
Entry into service of A320 Sharklets: Effects on Flight Operations and Performance Documentation
New LED design strobe & navigation lights • Blue light below the strobe & nav lights flashes when the replacement of
the LED is required by the maintenance personnel
Load Alleviation Function (LAF) • Wing load reduction through upward deflection of ailerons/spoilers • MTOW limited to 76 400kg (168 430 lbs) in case of failure of spoilers 4 or 5
(MMEL items updated accordingly)

FCOM/QRH Performance tables updated
• The following tables were updated to reflect the Sharklets performance improvement:

Performance Data Simplification: Objectives
Entry into service of A320 Sharklets: Effects on Flight Operations and Performance Documentation
• No multiplication of the performance pages (mixed fleet)
To maintain a Simple documentation
• More accurate calculations • Optimized results • Reduced error risk
To Promote the use of performance programs
• A first step in the global flight ops documentation simplification project

Holding performance PER-HLD
One engine inoperative performance PER-OEI & QRH FPE-OEI
Flight without cabin pressure performance PRO-SPO-20 & QRH FPE-CAB

Sharklets vs non Sharklet
Result The non-Sharklet tables are conservative, and can still be used for dispatch and in flight for the Sharklets aircraft
Since most operators use optimized performance computations and not the old paper based calculations
In order to get the full Sharklets benefit, Airbus recommends the use of performance programs
Decision To keep some tables similar to non-Sharklet aircraft

Performance data simplification: MMEL • Flight Ops Performance analysis process
• Same process as for FCOM/QRH • MMEL “paper” penalties cover the whole takeoff and landing environmental envelope • Not available for wet & contaminated runways
Entry into service of A320 Sharklets: Effects on Flight Operations and Performance Documentation
MMEL section MO Reference Spoiler 1 or 3 MO-27-64-02A
Spoilers 1 and 2 MO-27-64-04A
Ground Spoiler Control System MO-27-92-02A
Wing Anti-ice Control Valve MO-30-11-01A
Main Wheel Brake MO-32-42-01A
Minimum Idle on Ground MO-73-20-05A
Result The MMEL paper penalties are too penalizing for dispatch
Decision Paper penalties for takeoff/landing performance calculations are replaced by a performance computation requirement

Summary
• The use of performance program (PEP or equivalent) enables: • Reduced risk of errors • Optimized and Accurate results • Simplified documentation:
• Unique MMEL Operational Procedure from Sharklets onwards • Documentation homogeneity improved
• Full benefit of the Sharklets performance
