# 4.5 Climb

### Objective

To establish a stable and efficient climb profile after takeoff.

</div>### After Takeoff Flow

At acceleration altitude:

**PF:**

- Reduce pitch attitude
- Select climb profile

**PM:**

- Monitor speed increase

</div>### Flap Retraction

- Retract flaps according to speed schedule
- Ensure aircraft is clean (Flaps 0)

</div>### Thrust Setting

- Thrust Levers → CL detent

</div>### Autopilot

- Engage when conditions are met (see 4.4)

</div>### Standard Procedure

- **Climb Mode → MANAGED**
- **Speed → MANAGED**

The aircraft shall follow:

- FMGS vertical profile
- SID constraints
- Pre-programmed speed schedule

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

</div>### Exceptions

Selected modes may only be used if:

- **ATC explicitly assigns:**
    - A specific speed
    - A specific vertical rate or altitude constraint
- **Operational reasons require intervention**, such as: 
    - Avoiding traffic
    - Weather deviations
    - Energy management corrections

</div>### Monitoring (PM)

- Both pilots must ensure:
    
    
    - The aircraft follows the intended vertical profile
    - Speed constraints are respected
    - No unintended mode changes occur

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

</div>### Passing Transition Altitude

- Set Standard Pressure (STD)

---

### During Climb

- As soon as its safe: Turn off the seat belt sign
- When passing FL250: Set Vertical Display Selector on Below

</div>### Key Principles

- “Managed by default – Selected only when required.”
- Maintain situational awareness
- Monitor automation continuously
- Anticipate level-off
