Study Notes
A220 Operations and Performance Notes
- Start configuration at 400/40 N2 for takeoff.
- Verify that "disco" indication does not appear in flight plan before submission.
Ctwo Briefing
- Operational aspects include brake settings, exit strategy, runway length, and remaining fuel.
- Navigation to be transferred with a specific heading and rearmed for approach.
- Monitor F2 overspeed; select speeds cautiously below limits.
- Set a configuration speed of 180 knots; maintain up to 30% during critical phases.
- Remove brakes gently to avoid excessive deceleration.
- Maintain speed of 6 knots for tight turns and reduce energy to 8 knots for landing approach.
Glideslope Management
- Ensure awareness of position relative to the glideslope; utilize full speed brakes or none at all.
- Maximum speed of 300 knots below 8,000 feet altitude.
- Before inputting arrival data, confirm the absence of "disco" on the via page.
Departure Procedures
- Utilize NADP procedures for departures and ensure reversers are ready for use.
- Cannot flex thrust settings within 5 degrees of flex temperature.
- Input N1 takeoff thrust and passenger numbers in the scratch pad.
- Set altimeter barometric settings as reminders.
Electrical and Systems Checks
- During first flight, check for weather and turbulence conditions.
- Review barometric settings, HUD, weather radar, and central task panel status.
- Monitor APU fuel consumption; will reset upon engine start.
- Conduct synoptic checks on air, electrical, and flight control systems.
Flight Operations
- Ensure alternative arrival routes cannot be entered on the first page; require navigation to the second page.
- Flap configuration V2 + 10 above flap 2 for safety.
- Set appropriate heading and navigation for VNAV mode configuration.
- Avoid pushing back with battery CB bat 9 engaged.
Performance Metrics and Adjustments
- Adjust speeds on the performance page based solely on QNH changes.
- Deceleration necessitates specific speed reduction procedures (F1).
- Monitor vertical manage and clear all previous altitude restrictions with vertical direct.
- Flap 4 configuration is designated solely for engine failure scenarios due to a single bleed source.
Approach and Landing
- Threats during missed approaches include potential auto-throttle dropout, which may cause flap overspeed issues.
- If climb thrust adjustments are made, revert back to auto mode to enable go-around procedures.
- Vpath management may change flight director mode if above the target path or using FLC.
Documentation and Regulations
- Crews are required to familiarize themselves with various operational manuals and performance computation documents.
- OM-A guidance emphasizes NOTAM assessments, performance calculations, and company departure protocols.
- Attention to typographical errors in operational landing distance charts and fuel planning requirements is crucial.
Fuel Planning
- Ensure compliance with minimum fuel over alternate requirements, which includes considerations for endurance, company buffers, final reserves, holding, and approach fuels.
- Use TO-2 as the derate setting unless operational requirements dictate a higher thrust.
Dynamic Updates
- Be aware of updates to the Dynamic Airport Database affecting default derate settings, impacting calculations and performance metrics.
