Overview

The FLIGHT parameter group (specifically FLIGHT_OPTIONS) is a high-level bitmask that enables or modifies miscellaneous flight behaviors across different vehicle types.

This is often a "catch-all" for options that don't belong to a specific sensor or flight mode.

Key Concepts

1. Flight Options Bitmask

The bits in this parameter toggle experimental or non-standard behaviors.

• Examples (Variable by Vehicle):
  • Force arming even if some checks are failing (Advanced/Dangerous).
  • Enable specific MAVLink status reporting.
  • Alter behavior of the GCS failsafe.

Parameter Breakdown

• FLIGHT_OPTIONS: Bitmask.

Integration Guide

• Recommendation: Leave at 0 (Default) unless you are looking for a specific feature documented in the ArduPilot Wiki (e.g., "Set bit 5 of FLIGHT_OPTIONS to enable X").
