4.3 Taxi
Objective
To safely maneuver the aircraft from stand to runway while maintaining full control, situational awareness and ground crew safety.
Taxi Phase Definition
The taxi phase begins when:
- Pushback is completed
OR - Aircraft starts moving under its own power (self-maneuvering stand)
Taxi Clearance
PF: Requests taxi clearance
PM: Handles ATC communication
Taxi Procedure
PF:
- Releases parking brake
- Applies minimum thrust required to initiate movement
Thrust Management
- Use IDLE thrust whenever possible
- Apply thrust only to start movement
- Avoid continuous thrust application
Steering
- Nose wheel steering via tiller (PF)
- Rudder pedals for small corrections
- Use smooth and controlled inputs
Speed Control
- Standard taxi speed: ~20 kt
- Outside apron: max 30 kt
- Tight turns: max 15 kt
Brake Usage
- Apply brakes smoothly
- Avoid aggressive braking
- Maintain passenger comfort
Self Maneuvering / 180° Turns
At stands where no pushback is used and a self-turn (e.g. 180°) is required:
Procedure
PF:
- Release parking brake
- Use minimum thrust only
- Initiate slow, controlled turn
Speed & Control
- Maintain very low speed
- Avoid tight or aggressive steering
- Aircraft should roll smoothly through the turn
Lighting Policy (Ground Safety)
During initial movement (nose still facing stand/apron):
- Taxi Lights → OFF
- Runway Turnoff Lights → OFF
Once aligned with taxi direction:
- Taxi Lights → TAXI
- Runway Turnoff Lights → ON
Purpose
- Prevent blinding ground personnel
- Increase apron safety
- Ensure professional operation
Taxi Lights Configuration
During normal taxi:
- Taxi Lights → TAXI
- Runway Turnoff Lights → ON
- Landing Lights → OFF
Monitoring (PM)
- Brake temperature
- Taxi route
- External traffic
- Clearance compliance
Flight Control Check
Performed during taxi:
PF: “Flight Controls Check”
PM monitors ECAM:
- Full and free movement
- Correct deflection
Before Takeoff Preparation
- Complete Before Takeoff Checklist
- Verify aircraft configuration
Key Principles
- Maintain situational awareness at all times
- Taxi with low energy and high precision
- Protect ground crew through proper light usage
Core Rule
“Taxi is a low-energy phase – precision over speed.”
Outcome
A correct taxi ensures:
- Safe ground operations
- Reduced workload before takeoff
- Proper aircraft positioning
Second Engine Start (Single Engine Taxi Operations)
Objective
To ensure both engines are available and stabilized prior to takeoff.
Timing
👉 The second engine must be started:
- At latest 5 minutes before expected takeoff
Procedure
- Start remaining engine according to Engine Start SOP (4.2)
- Ensure full stabilization before runway entry
Monitoring
- Confirm engine parameters stable
- Verify no abnormal indications
- Complete required after start flow
Operational Note
- Plan engine start early enough to avoid:
- Time pressure
- Delays at holding point
Core Rule
“Be ready before the runway – not on it.”
