What is T-P on Airbus A320? (Turn Point)

The Airbus A320 is a popular narrow-body aircraft used by airlines around the world. It is known for its reliability, efficiency, and advanced technology. One important feature of the A320 is the Turn Point (T-P), which plays a key role in the aircraft’s navigation system. In this article, we will explore what Turn Point is and how it is used on the Airbus A320.

The Importance of Turn Point

The Turn Point on the Airbus A320 is a significant part of the flight management system (FMS). It is a specific location in the flight plan where the aircraft will change its direction during a flight. The FMS calculates the Turn Point based on various factors such as the aircraft’s current position, speed, altitude, wind direction, and the desired flight path.

The Turn Point is crucial for maintaining an efficient route and optimizing fuel consumption. By accurately calculating the Turn Point, the FMS can determine the most efficient path for the aircraft to travel, considering factors such as wind conditions and air traffic. This helps reduce fuel burn and overall operating costs for the airline.

How Turn Point is Calculated

The calculation of the Turn Point on the Airbus A320 involves complex algorithms within the flight management system. These algorithms take into account various parameters to determine the optimal point and angle for the aircraft to make a turn.

One of the key factors considered in the calculation is the aircraft’s ground speed. Ground speed refers to the speed at which an aircraft is moving relative to the Earth’s surface. By analyzing the ground speed and taking into account the desired flight path, the FMS can calculate the precise Turn Point to ensure a smooth and efficient turn.

The FMS also considers the wind conditions, including both direction and speed. By factoring in the wind, the system can adjust the Turn Point accordingly. For example, if the wind is blowing from the left, the FMS will calculate a Turn Point that allows the aircraft to counteract the wind and maintain the desired flight path.

Benefits of Turn Point on Airbus A320

The Turn Point feature on the Airbus A320 offers several benefits for airlines and pilots. Here are some key advantages:

1. Fuel Efficiency: By accurately calculating the Turn Point, the FMS helps optimize fuel consumption during a flight. This can result in significant cost savings for airlines, especially on long-haul routes.

2. Flight Path Optimization: The Turn Point allows for precise control of the aircraft’s flight path. This is particularly important during approaches and departures, where it is crucial to follow specific routes and avoid obstacles.

3. Enhanced Safety: The Turn Point ensures that the aircraft remains within predetermined airspace boundaries. This helps maintain separation from other aircraft and reduces the risk of mid-air collisions.


The Turn Point is a vital component of the Airbus A320’s flight management system. It helps optimize fuel consumption, ensures efficient flight paths, and enhances safety. By accurately calculating the Turn Point, the aircraft can navigate smoothly, reducing operating costs for airlines and providing a more comfortable experience for passengers. The advanced technology and reliability of the Airbus A320, including features like the Turn Point, make it a popular choice among airlines worldwide.
