The normal procedures for the Airbus A320 are standardized steps performed by the flight crew to ensure safe and efficient operation of the aircraft. These procedures are outlined in the FCOM (Flight Crew Operating Manual) and vary slightly depending on airline-specific SOPs. Below is an overview of the key phases of flight and the associated normal procedures:

1. Preflight

• Cockpit Preparation

  • Turn on BAT 1 and BAT 2.

  • Connect to External Power or start the APU if external power is unavailable.

  • Perform system initialization, including:

    • Aligning the ADIRS (Air Data Inertial Reference System).

    • Setting up the FMGC (Flight Management and Guidance Computer).

    • Verifying aircraft status on the ECAM.

  • Perform all checklists (e.g., Preflight Checklist, Cockpit Preparation Checklist).

2. Engine Start

• Before Engine Start

  • Coordinate with ground crew for pushback and start clearance.

  • Set Beacon Light to ON.

  • Check the area is clear and ground equipment is disconnected.

• Engine Start

  • Set the Engine Mode Selector to IGN/START.

  • Start engines (typically engine 2 first, then engine 1).

  • Monitor engine parameters on ECAM (e.g., N1, N2, EGT).

• After Engine Start

  • Set the Engine Mode Selector to NORM.

  • Perform the after-start flow and checklist.

3. Taxi

• Configure for taxi:

  • Set Flaps for takeoff (per FMGC settings).

  • Arm the Ground Spoilers.

  • Perform a flight controls check via the ECAM page.

  • Verify brake and nosewheel steering operation.

  • Taxi to the departure runway as cleared by ATC.

4. Takeoff

• Perform the Before Takeoff Checklist.

• Line up on the runway and set TOGA (Takeoff/Go Around) or FLEX thrust as required.

• Monitor takeoff parameters:

  • "80 knots, thrust set, SRS, NAV."

  • At V1, decision is made to continue or abort takeoff.

  • At VR, rotate the aircraft to the proper pitch attitude.

5. Climb

• Retract landing gear at Positive Rate.

• Retract flaps and slats per the speed schedule.

• Engage Autopilot if desired.

• Follow departure procedures and comply with ATC clearances.

6. Cruise

• Perform routine system checks.

• Monitor fuel and engine parameters.

• Maintain situational awareness and respond to ATC instructions.

7. Descent and Approach

• Prepare for descent using the Arrival Briefing:

  • Review weather, landing configuration, and runway data.

• Perform the Descent Checklist.

• Configure for approach:

  • Set slats/flaps and landing gear.

  • Arm the ground spoilers.

8. Landing

• Perform the Landing Checklist.

• Touchdown and deceleration:

  • Use reverse thrust and brakes as needed.

  • Exit the runway when safe and cleared by ATC.

9. Taxi to Gate

• Perform the After Landing Checklist:

  • Retract flaps.

  • Disarm ground spoilers.

  • Turn off landing lights.

  • Start the APU if required.

10. Shutdown

• Park the aircraft and set the parking brake.

• Perform the Parking Checklist:

  • Turn off engines using ENG MASTER switches.

  • Connect to external power or leave the APU running as needed.

  • Switch off unnecessary systems and lights.

11. Securing the Aircraft

• Perform the Securing Checklist:

  • Turn off the APU (if not required).

  • Set BAT 1 and BAT 2 to OFF.

These steps ensure that the A320 operates efficiently and complies with safety regulations. Adjustments may be required based on specific operational scenarios or airline SOPs.
