</div>### Crew Concept

- **PF (Pilot Flying):**
    - Reviews flight plan
    - Performs MCDU setup
    - Cross-checks entries
- **PM (Pilot Monitoring):**
    - Performs cockpit setup
    - Powers aircraft systems
    - Executes checklists

</div>### Initial Cockpit Setup

**PM:**

1. BAT 1 + BAT 2 → ON
2. External Power → ON (if available)

**Check:**

- ECAM displays active
- No abnormal warnings

</div>### Overhead Panel Setup (PM)

- Fuel Pumps → ON
- Hydraulic Panel → CHECK
- Electrical Panel → CHECK
- Air Conditioning → SET

**ADIRS:**

- Set all IR selectors → NAV

<div contenteditable="false" id="bkmrk--3">---

</div>### Cockpit Lighting (PM)

- Set as required for conditions

</div>### MCDU Initialization (PF)

#### INIT A Page:

- FROM / TO → Set departure &amp; arrival airport
- Flight Number → INSERT
- Cost Index → SET
- Cruise Level → SET

<div contenteditable="false" id="bkmrk--5">---

</div>#### Flight Plan Page:

- Insert route (airways / waypoints)
- Check for discontinuities
- Insert SID (Standard Instrument Departure)
- Verify routing

<div contenteditable="false" id="bkmrk--6">---

</div>#### INIT B Page:

- Block Fuel → INSERT
- Zero Fuel Weight → INSERT

<div contenteditable="false" id="bkmrk--7">---

</div>#### Performance Setup:

- V1 / VR / V2 → CALCULATE &amp; INSERT
- FLEX Temperature → SET (if applicable)
- Thrust Reduction / Acceleration Altitude → SET

<div contenteditable="false" id="bkmrk--8">---

</div>### FMGS Crosscheck

**PM cross-checks all entries:**

- Route correctness
- Fuel values
- Performance data

<div contenteditable="false" id="bkmrk--9">---

</div>### Flight Instruments Setup

**Both pilots:**

- Set Barometric Reference
- Set Initial Altitude
- Set Vertical Display Selector on Above

<div contenteditable="false" id="bkmrk--10">---

</div>### Takeoff Briefing (PF)

Must include:

- Runway
- SID
- Initial altitude
- Expected routing
- Threats &amp; considerations

</div>### Before Start Checklist

Performed when all preparation is complete.

</div>### Key Principles

- Always verify MCDU entries
- Cross-check between PF and PM
- Avoid rushing the setup

<div contenteditable="false" id="bkmrk--13">---

</div>### Philosophy

A correct cockpit preparation ensures:

- Reduced workload during taxi and takeoff
- Fewer errors in flight
- Better situational awareness

A rushed or incomplete setup increases risk significantly.
