ATTI Mode: A Guide

ATTI Mode: A Comprehensive Guide

ATTI mode, short for Attitude Mode, is the most hands-on way to operate a drone. It gives the pilot full control over the aircraft's orientation without relying on GPS or visual positioning systems.

As drone technology continues to evolve, many modern drones now come with advanced automation features that make flying easier and safer. However, there are still situations where ATTI mode is not just useful but essential.

One of the main reasons to use ATTI mode is during indoor flights where GPS signals are weak or completely unavailable. In such environments, optical sensors may also struggle, making manual control the best option.

In ATTI mode, the drone’s sensors are disabled, and the pilot must manually adjust the drone’s attitude. This means the drone can drift or lose altitude if not handled carefully. Pilots should activate ATTI mode when they notice erratic behavior caused by sensor limitations in challenging conditions.

What Is ATTI Mode?

ATTI mode is a flight setting that disables all automated assistance, including GPS and optical sensors. In this mode, the drone does not hold its position or correct itself—it relies entirely on the pilot’s input.

Most pilots fly in GPS or OPTI mode, which offer stability and ease of use. But in ATTI mode, the drone becomes more like a traditional remote-controlled aircraft, requiring skill and experience to handle effectively.

When to Use ATTI Mode

While ATTI mode is less common in consumer drones today, it remains crucial for specific applications. Especially in indoor environments, where GPS signals are blocked or unreliable, ATTI mode becomes the go-to choice.

Indoor inspections—such as those in mines, sewers, and other confined spaces—often require ATTI mode. These areas lack satellite coverage, making it impossible to rely on GPS-based navigation.

The mining industry has been one of the early adopters of indoor drone technology. Drones like the Elios 3 are designed specifically for GPS-denied environments, using ATTI mode to navigate safely underground.

Common Use Cases for ATTI Mode

ATTI mode is particularly useful when GPS signals are weak or absent. Here are some common scenarios where it comes into play:

  • Indoor inspections. Drones are used to inspect boilers, sewers, tanks, and mines where GPS is out of range.

  • Bridge inspections. Large metal structures can interfere with GPS signal accuracy.

  • Building inspections. Concrete and steel can cause signal interference, making GPS unreliable.

  • Critical infrastructure. Sensitive areas like military bases often restrict GPS use for security reasons.

The Elios 3 is built for these demanding environments, offering precise control through ATTI mode.

How Does ATTI Work?

In ATTI mode, the drone’s automatic stabilization systems are turned off. Pilots take full control of the aircraft, relying on an onboard barometer to maintain altitude. However, wind and obstacles can still affect the drone’s movement.

What Conditions Can Trigger ATTI Mode Automatically?

  • Flying over reflective or featureless surfaces
  • Dirt or debris on vision sensors
  • Flying near large metal or concrete structures
  • Using high-speed flight modes

Benefits of Flying in ATTI Mode

While ATTI mode is more challenging, it offers several advantages:

1. Better Preparedness for Emergencies

Knowing how to fly in ATTI mode helps you stay calm and in control during unexpected situations like signal loss or interference.

2. Ideal for Indoor Flights

Indoors, GPS is often unavailable. ATTI mode allows you to navigate safely with the help of a skilled pilot and barometric sensors.

3. Smoother Video Footage

Without automatic corrections, the footage tends to be smoother. Many professionals prefer ATTI for high-quality video shoots.

ATTI Mode Flying Tips

Flying in ATTI mode takes time and practice. Here are some tips to get started:

1. Start Slowly

If you're used to GPS-assisted flight, transitioning to ATTI can be tricky. Begin with basic maneuvers like takeoff, hover, and landing before moving on to more complex patterns.

2. Practice in Open Spaces

Find a large, open area free of people and obstacles. This will give you room to learn without the risk of crashing.

3. Watch the Weather

Wind can significantly impact your ability to control the drone. Avoid flying in strong winds until you gain more experience.

4. Use an Affordable Drone

Start with a budget-friendly model to build confidence. You can always upgrade once you feel comfortable with ATTI mode.

The Future of ATTI Mode

Although consumer drones are moving away from manual flight modes, ATTI remains important in specialized industries. As more sectors adopt drones for indoor operations, demand for ATTI-capable models will grow.

Whether you're a professional or hobbyist, mastering ATTI mode is a valuable skill. It prepares you for real-world challenges and expands your capabilities as a drone pilot.

Other Drone Flight Modes

Alongside ATTI mode, there are three other common flight settings: ASSIST, GPS, and OPTI.

What is ASSIST Mode?

ASSIST mode uses sensors to keep the drone stable and stationary. It’s ideal for beginners but can fail in low-light or featureless environments.

What is GPS Mode?

GPS mode uses satellite signals to track the drone’s location. It enables advanced features like Return to Home and Follow Me.

What is OPTI Mode?

OPTI mode uses optical sensors for stabilization, but not GPS. It’s better than ATTI for indoor flights, but still requires careful handling.
