4.5 Climb

Objective

To establish a stable and efficient climb profile after takeoff.

After Takeoff Flow

At acceleration altitude:

PF:

• Reduce pitch attitude
• Select climb profile

PM:

• Monitor speed increase

Flap Retraction

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

Thrust Setting

• Thrust Levers → CL detent

Autopilot

• Engage when conditions are met (see 4.4)

Standard Procedure

• Climb Mode → MANAGED
• Speed → MANAGED

The aircraft shall follow:

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

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

Monitoring (PM)

• Engine parameters
• Vertical speed
• Flight path vs clearance

Passing Transition Altitude

• Set Standard Pressure (STD)

Key Principles

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