Pre-Arm Checks

The Reflex implements a series of pre-flight checks to ensure the drone is in a safe state to arm and fly. These checks include:

  • Throttle Stick Down: The throttle stick must be in the down position, indicating a zero throttle input.

  • Drone Standing Still: The drone should be stationary on the ground, ensuring that it is not in motion before arming.

  • Drone Upright: The drone must be in an upright position, with its orientation aligned properly.

  • Battery Level Above Critical: The battery level needs to be above the 'Low Cell Voltage', ensuring sufficient power for safe flight.

  • Gyro and Accelerometer Check: The gyroscope and accelerometer sensors are checked to ensure they are functioning correctly.

  • State Estimator Running: The state estimator, responsible for estimating the drone's position and attitude, is verified to be running properly.

  • Kill Switch Not Active: The kill switch on the RC (Remote Control) should be turned off to enable normal flight operations.
