<long_desc>If ASPD_DO_CHECKS is set to true, then airspeed estimation can fallback from what specified in ASPD_PRIMARY to secondary source (other airspeed sensors, groundspeed minus windspeed).</long_desc>

<long_desc>This specifies the minimum airspeed test ratio required to trigger a failsafe. Larger values make the check less sensitive, smaller values make it more sensitive. Start with a value of 1.0 when tuning. When tas_test_ratio is > 1.0 it indicates the inconsistency between predicted and measured airspeed is large enough to cause the navigation EKF to reject airspeed measurements. The time required to detect a fault when the threshold is exceeded depends on the size of the exceedance and is controlled by the ASPD_FS_INTEG parameter.</long_desc>
<long_desc>This sets the time integral of airspeed test ratio exceedance above ASPD_FS_INNOV required to trigger a failsafe. For example if ASPD_FS_INNOV is 1 and estimator_status.tas_test_ratio is 2.0, then the exceedance is 1.0 and the integral will rise at a rate of 1.0/second. A negative value disables the check. Larger positive values make the check less sensitive, smaller positive values make it more sensitive.</long_desc>
<long_desc>Turns the automatic airspeed scale (scale from IAS to CAS/EAS) on or off. It is recommended level (keeping altitude) while performing the estimation. Set to 1 to start estimation (best when already flying). Set to 0 to end scale estimation. The estimated scale is then saved in the ARSP_ARSP_SCALE parameter.</long_desc>

<long_desc>This is the minimum indicated airspeed at which the wing can produce 1g of lift. It is used by the airspeed sensor fault detection and failsafe calculation to detect a significant airspeed low measurement error condition and should be set based on flight test for reliable operation.</long_desc>
<short_desc>Airspeed fault detection delay before RTL (Experimental)</short_desc>
<long_desc>RTL delay after bad airspeed measurements are detected if COM_ASPD_FS_ACT is set to 4. Ensure the COM_ASPD_STALL parameter is set correctly before use. The failsafe start and stop delays are controlled by the COM_TAS_FS_T1 and COM_TAS_FS_T2 parameters. Additional protection against persistent airspeed sensor errors can be enabled using the COM_TAS_FS_INNOV parameter, but these addtional checks are more prone to false positives in windy conditions.</long_desc>

<long_desc>A non-zero, positive value specifies the time-out period in seconds after which the vehicle will be automatically disarmed in case a landing situation has been detected during this period.
