Overview

The AUTOLAND parameter group appears to contain legacy or alias parameters related to the Automatic Landing sequence in ArduPlane.

Note: In modern ArduPilot firmware, most landing configuration is handled by:

  • LAND_ group: For Copter landing speeds.
  • TECS_ group: For Plane glide slope and descent rates.
  • RTL_AUTOLAND: To trigger landing after RTL.
  • Mission Items: DO_LAND_START, NAV_LAND waypoints.

Key Parameters (Legacy/Reference)

  • AUTOLAND_WP_ALT: Likely referred to the altitude of the final approach waypoint.
  • AUTOLAND_OPTIONS: Bitmask for behavior (e.g., flare logic).

Integration Guide

For setting up Auto Landing in modern firmware:

  1. Plane: Use a mission with DO_LAND_START -> NAV_LOITER_TO_ALT -> NAV_LAND.
  2. Copter: Use LAND_SPEED and LAND_SPEED_HIGH to tune the descent.

Developer Notes

  • These parameters may not exist in the current ardupilot codebase and might be artifacts of older documentation generation.

AUTOLAND_OPTIONS

Default 0

Landing options bitmask (AUTOLAND_OPTIONS)

Description

Configuration bitmask for various landing behaviors.

Tuning & Behavior

  • Default Value: 0
  • Bitmask:
    • 0: honor min throttle during landing flare
    • 1: Increase Target landing airspeed constraint From Trim Airspeed to AIRSPEED_MAX

AUTOLAND_WP_ALT

m
Default 50
Range 0 200

Takeoff mode altitude (AUTOLAND_WP_ALT)

Description

Defines the target altitude for the aircraft to reach when in "Takeoff" mode.

Tuning & Behavior

  • Default Value: 50 m
  • Range: 0 to 200 m

AUTOLAND_WP_DIST

m
Default 200
Range 0 500

Takeoff mode distance (AUTOLAND_WP_DIST)

Description

Defines the horizontal distance from the takeoff point to the designated loiter point where the aircraft will wait after completing the initial climb.

Tuning & Behavior

  • Default Value: 200 m
  • Range: 0 to 500 m
