See the documentation for your external compass for the right value. The correct orientation should give the X axis forward, the Y axis to the right and the Z axis down. So if your aircraft is pointing west it should show a positive value for the Y axis, and a value close to zero for the X axis. On a PX4 or Pixhawk with an external compass the correct value is zero if the compass is correctly oriented. NOTE: This orientation is combined with any AHRS_ORIENTATION setting.</Description>

      <Description>enable terrain data. This enables the vehicle storing a database of terrain data on the SD card. The terrain data is requested from the ground station as needed, and stored for later use on the SD card. To be useful the ground station must support TERRAIN_REQUEST messages and have access to a terrain database, such as the SRTM database.</Description>

      <DisplayName>Terrain grid spacing</DisplayName>
      <Description>Distance between terrain grid points in meters. This controls the horizontal resolution of the terrain data that is stored on te SD card and requested from the ground station. If your GCS is using the worldwide SRTM database then a resolution of 100 meters is appropriate. Some parts of the world may have higher resolution data available, such as 30 meter data available in the SRTM database in the USA. The grid spacing also controls how much data is kept in memory during flight. A larger grid spacing will allow for a larger amount of data in memory. A grid spacing of 100 meters results in the vehicle keeping 12 grid squares in memory with each grid square having a size of 2.7 kilometers by 3.2 kilometers. Any additional grid squares are stored on the SD once they are fetched from the GCS and will be demand loaded as needed.</Description>

If 2, require rudder stick or GCS arming and send 0 PWM to throttle channel when disarmed. See the ARMING_CHECK_* parameters to see what checks are done before arming. Note, if setting this parameter to 0 a reboot is required to arm the plane.  Also note, even with this parameter at 0, if ARMING_CHECK parameter is not also zero the plane may fail to arm throttle at boot due to a pre-arm check failure.</Description>

If your GCS is using the worldwide SRTM database then a resolution of 100 meters is appropriate. Some parts of the world may have higher resolution data available, such as 30 meter data available in the SRTM database in the USA. The grid spacing also controls how much data is kept in memory during flight. A larger grid spacing will allow for a larger amount of data in memory. A grid spacing of 100 meters results in the vehicle keeping 12 grid squares in memory with each grid square having a size of 2.7 kilometers by 3.2 kilometers. Any additional grid squares are stored on the SD once they are fetched from the GCS and will be demand loaded as needed.</Description>

If you set this to 0 then the top connector on the sensor needs to be the dynamic pressure. If set to 1 then the bottom connector needs to be the dynamic pressure. If set to 2 (the default) then the airspeed driver will accept either order. The reason you may wish to specify the order is it will allow your airspeed sensor to detect if the aircraft it receiving excessive pressure on the static port, which would otherwise be seen as a positive airspeed.</Description>

      <Description>Period in seconds of L1 tracking loop. This parameter is the primary control for agressiveness of turns in auto mode. This needs to be larger for less responsive airframes. The default of 30 is very conservative, and for most RC aircraft will lead to slow and lazy turns. For smaller more agile aircraft a value closer to 20 is appropriate, or even as low as 10 for some very agile aircraft. When tuning, change this value in small increments, as a value that is much too small (say 5 or 10 below the right value) can lead to very radical turns, and a risk of stalling.</Description>

      <Description>这个参数用来设置在最初的起飞阶段，升降舵面的应用比例。这个功能是用于在地面滑行时，保持住后三点飞机的尾轮（转向轮）,保持飞机在起飞时的方向稳定。这个参数应该结合 TKOFF_TDRAG_SPD1 和 GROUND_STEER_ALT 参数一起进行地面转向控制的调整。0值为忽略在起飞时的尾轮保持，并用在投掷和弹射起飞模式下。对于后三点飞机，通常设置为100，这将在起飞时使升降舵处于爬升满舵状态。0值适用于大多数前三点起落架，但是有一些前三点飞机需要在起飞时让升降舵向下，用来保持飞机在起飞加速时，前轮能保持对方向的控制（设置为-20到-30）。除非发现起飞离地前，前轮不能很好的接触地面，否则不要设置为负值。前三点飞机使用大幅度的升降舵向下时，会造成转向不灵，所以调试时，每次最多降低10%来测试。</Description>

      <DisplayName>地面站失控保护</DisplayName>
      <Description>是否允许地面站数据传输的失控保护功能。如果FS_LONG_TIMEOUT参数设定的时间依然没有MAVLink心跳信号，将触发失控保护。这里有两种情况可以设置，设置为1时，如果飞控收不到MAVLink心跳信号，将触发失控保护。设置为2意味着不管是收不到飞控心跳信号，还是无法接收飞控的更新数据，都会触发失控保护。这个情况在 RADIO_STATUS里的remrssi项显示为0. (一般是由于在单向传输数据的地面站或飞控端的无线电噪音造成的）。警告：允许这个选项可能会在地面调试的时候，造成电机意外启动，所以应设置解锁要求ARMING_REQUIRED参数为允许。</Description>

      <Description>If set to a non-zero value then this is an RC input channel number to use for testing manual control in case the main FMU microcontroller on a PX4 or Pixhawk fails. When this RC input channel goes above 1750 the FMU will stop sending servo controls to the PX4IO board, which will trigger the PX4IO board to start using its failsafe override behaviour, which should give you manual control of the aircraft. That allows you to test for correct manual behaviour without actually crashing the FMU. This parameter is normally only set to a non-zero value for ground testing purposes. When the override channel is used it also forces the PX4 safety switch into an armed state. This allows it to be used as a way to re-arm a plane after an in-flight reboot. Use in that way is considered a developer option, for people testing unstable developer code. Note that you may set OVERRIDE_CHAN to the same channel as FLTMODE_CH to get PX4IO based override when in flight mode 6. Note that when override is triggered the 6 auxillary output channels on Pixhawk will no longer be updated, so all the flight controls you need must be assigned to the first 8 channels.</Description>

      <DisplayName>Steering Time Constant</DisplayName>
      <Description>This controls the time constant in seconds from demanded to achieved steering angle. A value of 0.75 is a good default and will work with nearly all rovers. Ground steering in aircraft needs a bit smaller time constant, and a value of 0.5 is recommended for best ground handling in fixed wing aircraft. A value of 0.75 means that the controller will try to correct any deviation between the desired and actual steering angle in 0.75 seconds. Advanced users may want to reduce this time to obtain a faster response but there is no point setting a time less than the vehicle can achieve.</Description>

So if your aircraft is pointing west it should show a positive value for the Y axis, and a value close to zero for the X axis. On a PX4 or Pixhawk with an external compass the correct value is zero if the compass is correctly oriented. NOTE: This orientation is combined with any AHRS_ORIENTATION setting.</Description>

      <Description>Period in seconds of L1 tracking loop. This parameter is the primary control for agressiveness of turns in auto mode. This needs to be larger for less responsive airframes. The default of 30 is very conservative, and for most RC aircraft will lead to slow and lazy turns. For smaller more agile aircraft a value closer to 20 is appropriate, or even as low as 10 for some very agile aircraft. When tuning, change this value in small increments, as a value that is much too small (say 5 or 10 below the right value) can lead to very radical turns, and a risk of stalling.</Description>

      <Description>When enabled this tells the APM to skip the normal gyroscope calibration at startup, and instead use the saved gyro calibration from the last flight. You should only enable this if you are careful to check that your aircraft has good attitude control before flying, as some boards may have significantly different gyro calibration between boots, especially if the temperature changes a lot. If gyro calibration is skipped then APM relies on using the gyro drift detection code to get the right gyro calibration in the few minutes after it boots. This option is mostly useful where the requirement to hold the vehicle still while it is booting is a significant problem.</Description>

    <COMPASS_ORIENT>
      <DisplayName>Compass orientation</DisplayName>
      <Description>The orientation of the compass relative to the autopilot board. This will default to the right value for each board type, but can be changed if you have an external compass. See the documentation for your external compass for the right value. The correct orientation should give the X axis forward, the Y axis to the right and the Z axis down. So if your aircraft is pointing west it should show a positive value for the Y axis, and a value close to zero for the X axis. On a PX4 or Pixhawk with an external compass the correct value is zero if the compass is correctly oriented. NOTE: This orientation is combined with any AHRS_ORIENTATION setting.</Description>
