<short_desc>Time-out for auto disarm if too slow to takeoff</short_desc>
<long_desc>A non-zero, positive value specifies the time after arming, in seconds, within which the vehicle must take off (after which it will automatically disarm). A zero or negative value means that automatic disarming triggered by a pre-takeoff timeout is disabled.</long_desc>
<long_desc>A non-zero, positive value specifies the time after arming, in seconds, within which the vehicle must take off (after which it will automatically disarm). This is set to 25 seconds to ensure a system will not disarm if the pilot is not immediately taking off, but not so long that a system is completely forgotten about. A zero or negative value means that automatic disarming triggered by a pre-takeoff timeout is disabled.</long_desc>

<long_desc>Condition to enter the prearmed state, an intermediate state between disarmed and armed in which non-throttling actuators are active.</long_desc>
<long_desc>If this parameter is enabled then the estimator will make use of the range finder measurements to estimate it's height even if range sensor is not the primary height source. It will only do so if conditions for range measurement fusion are met. This enables the range finder to be used during low speed and low altitude operation, eg takeoff and landing, where baro interference from rotor wash is excessive and can corrupt EKF state estimates. It is intended to be used where a vertical takeoff and landing is performed, and horizontal flight does not occur until above EKF2_RNG_A_HMAX. If vehicle motion causes repeated switching between the primary height sensor and range finder, an offset in the local position origin can accumulate. Also range finder measurements are less reliable and can experience unexpected errors. For these reasons, if accurate control of height relative to ground is required, it is recommended to use the MPC_ALT_MODE parameter instead, unless baro errors are severe enough to cause problems with landing and takeoff.</long_desc>
<short_desc>Cutoff frequency for angular acceleration (D-Term filter)</short_desc>
<long_desc>The cutoff frequency for the 2nd order butterworth filter used on the time derivative of the measured angular velocity, also known as the D-term filter in the rate controller. The D-term uses the derivative of the rate and thus is the most susceptible to noise. Therefore, using a D-term filter allows to increase IMU_GYRO_CUTOFF, which leads to reduced control latency and permits to increase the P gains. A value of 0 disables the filter.</long_desc>
