PX4 Flight Modes Overview

This topic is under construction. It is not complete and has not been fully reviewed.

Flight modes define how the autopilot responds to remote control input, and how it manages vehicle movement during fully autonomous flight.

The modes provide different types/levels of autopilot assistance to the user (pilot), ranging from automation of common tasks like takeoff and landing, through to mechanisms that make it easier to regain level flight, hold the vehicle to a fixed path or position, etc.

This topic provides an overview of the available the flight modes, and the (mostly minor) differences in their default behaviour in multicopter (MC), fixed-wing (FW) and VTOL frames.

More detailed information about specific flight modes can be found in Flying > Flight Modes.

Switching Between Modes

Pilots can transition between flight modes using switches on the remote control or with a ground control station (see Flight Mode Configuration).

Not all flight modes are available on all vehicle types, and some modes behave differently on different vehicle types.

Some flight modes make sense only under specific pre-flight and in-flight conditions (e.g. GPS lock, airspeed sensor, vehicle attitude sensing along an axis). PX4 will not allow transitions to those modes until the right conditions are met.

Autonomous and Manual Modes

Flight Modes are either manual or autonomous. Manual modes are those where the user has control over vehicle movement via the RC control sticks (or joystick), while autonomous modes are fully controlled by the autopilot, and require no pilot/remote control input.

Some manual modes may have autopilot-assisted mechanisms to make it easier to gain or restore controlled flight. For example, most modes will level out the vehicle when the RC sticks are centered.

Manual modes may further be divided into "easy" and "acrobatic" modes. In the easy modes, roll and pitch sticks set the vehicle angle, resulting in left-right and forward-back movement in the horizontal plane (respectively). Not only does this make movement predictable, but because angles are controlled, the vehicle is impossible to flip. In acrobatic modes RC sticks control the rate of angular rotation (around the respective axis). Vehicles can flip, and while more maneuverable, are harder to fly.

        <p>
          When under manual control the roll and pitch sticks control the angle of the vehicle (attitude), the yaw stick controls the rate of rotation above the horizontal plane, and the throttle controls altitude/speed.
        </p>

        <p>
          As soon as you release the control sticks they will return to the centre deadzone. The multicopter will level out and stop once the roll and pitch sticks are centered. The vehicle will then hover in place/maintain altitude - provided it is properly balanced, throttle is set appropriately, and no external forces are applied (e.g. wind). The craft will drift in the direction of any wind and you have to control the throttle to hold altitude.

          <a href="../flight_modes/land.md">Land mode</a> causes the vehicle to turn and land at the location at which the mode was engaged. Fixed wing landing logic and parameters are explained in the topic: <a href="../flying/fixed_wing_landing.md">Landing (Fixed Wing)</a>.

        <h2>
          Vertical Take Off and Landing (VTOL)
        </h2>

        <p>
          A VTOL aircraft can fly as either a multicopter or as fixed-wing vehicle. The multicopter mode is mainly used for take off and landing while the fixed wing mode is used for efficient travel and/or mission execution.
        </p>

        <p>
          Generally the flight modes for VTOL vehicles are the same as for <a href="#mc_flight_modes">multicopter</a> when flying in MC mode and <a href="#fw_flight_modes">fixed-wing</a> when flying in FW mode.
        </p>

        <p>
          The switch between modes is initiated either by the pilot using an RC switch or automatically by PX4 when needed in the Auto modes.
