Below TRIM_THROTTLE downtrim is added in proportion to the amount the throttle is below TRIM_THROTTLE. At zero throttle the full downpitch specified in this parameter is added. This parameter is meant to help keep airspeed up when flying in FBWA mode with low throttle, such as when on a landing approach, without relying on an airspeed sensor. A value of 2 degrees is good for many planes, although a higher value may be needed for high drag aircraft.

If you don't want glide slopes to be used in missions then you can set this to zero, which will disable glide slope calculations.

There are two types of stick mixing available. If you set STICK_MIXING to 1 then it will use "fly by wire" mixing, which controls the roll and pitch in the same way that the FBWA mode does. This is the safest option if you usually fly ArduPlane in FBWA or FBWB mode. If you set STICK_MIXING to 2 then it will enable direct mixing mode, which is what the STABILIZE mode uses. That will allow for much more extreme maneuvers while in AUTO mode.

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 plane still while it is booting is a significant problem.

    // @Description: Minimum GPS ground speed in m/s used by the speed check that un-suppresses throttle in auto-takeoff. This can be be used for catapult launches where you want the motor to engage only after the plane leaves the catapult, but it is preferable to use the TKOFF_THR_MINACC and TKOFF_THR_DELAY parameters for catapult launches due to the errors associated with GPS measurements. For hand launches with a pusher prop it is strongly advised that this parameter be set to a value no less than 4 m/s to provide additional protection against premature motor start. Note that the GPS velocity will lag the real velocity by about 0.5 seconds. The ground speed check is delayed by the TKOFF_THR_DELAY parameter.

Setting this value to 0 disables the acceleration test which means the ground speed check will always be armed which could allow GPS velocity jumps to start the engine. For hand launches and bungee launches this should be set to around 15.

    // @Description: This parameter sets the time delay (in 1/10ths of a second) that the ground speed check is delayed after the forward acceleration check controlled by TKOFF_THR_MINACC has passed. For hand launches with pusher propellers it is essential that this is set to a value of no less than 2 (0.2 seconds) to ensure that the aircraft is safely clear of the throwers arm before the motor can start. For bungee launches a larger value can be used (such as 30) to give time for the bungee to release from the aircraft before the motor is started.

    // @Param: TKOFF_TDRAG_ELEV
    // @DisplayName: Takeoff tail dragger elevator
    // @Description: This parameter sets the amount of elevator to apply during the initial stage of a takeoff. It is used to hold the tail wheel of a taildragger on the ground during the initial takeoff stage to give maximum steering. This option should be conbined with the TKOFF_TDRAG_SPD1 option and the GROUND_STEER_ALT option along with tuning of the ground steering controller. A value of zero means to bypass the initial "tail hold" stage of takeoff. Set to zero for hand and catapult launch. For tail-draggers you should normally set this to 100, meaning full up elevator during the initial stage of takeoff. For most tricycle undercarriage aircraft a value of zero will work well, but for some tricycle aircraft a small negative value (say around -20 to -30) will apply down elevator which will hold the nose wheel firmly on the ground during initial acceleration. Only use a negative value if you find that the nosewheel doesn't grip well during takeoff. Too much down elevator on a tricycle undercarriage may cause instability in steering as the plane pivots around the nosewheel. Add down elevator 10 percent at a time.

    // @DisplayName: Takeoff tail dragger speed1
    // @Description: This parameter sets the airspeed at which to stop holding the tail down and transition to rudder control of steering on the ground. When TKOFF_TDRAG_SPD1 is reached the pitch of the aircraft will be held level until TKOFF_ROTATE_SPD is reached, at which point the takeoff pitch specified in the mission will be used to "rotate" the pitch for takeoff climb. Set TKOFF_TDRAG_SPD1 to zero to go straight to rotation. This should be set to zero for hand launch and catapult launch. It should also be set to zero for tricycle undercarriages. For tail dragger aircraft it should be set just below the stall speed.

    // @DisplayName: Takeoff rotate speed
    // @Description: This parameter sets the airspeed at which the aircraft will "rotate", setting climb pitch specified in the mission. If TKOFF_ROTATE_SPD is zero then the climb pitch will be used as soon as takeoff is started. For hand launch and catapult launches a TKOFF_ROTATE_SPD of zero should be set. For all ground launches TKOFF_ROTATE_SPD should be set above the stall speed, usually by about 10 to 30 percent

    // @Param: TKOFF_THR_SLEW
    // @DisplayName: Takeoff throttle slew rate
    // @Description: This parameter sets the slew rate for the throttle during auto takeoff. When this is zero the THR_SLEWRATE parameter is used during takeoff. For rolling takeoffs it can be a good idea to set a lower slewrate for takeoff to give a slower acceleration which can improve ground steering control. The value is a percentage throttle change per second, so a value of 20 means to advance the throttle over 5 seconds on takeoff. Values below 20 are not recommended as they may cause the plane to try to climb out with too little throttle.

    // @DisplayName: FBWA taildragger channel
    // @Description: This is a RC input channel which when it goes above 1700 enables FBWA taildragger takeoff mode. It should be assigned to a momentary switch. Once this feature is enabled it will stay enabled until the aircraft goes above TKOFF_TDRAG_SPD1 airspeed, changes mode, or the pitch goes above the initial pitch when this is engaged or goes below 0 pitch. When enabled the elevator will be forced to TKOFF_TDRAG_ELEV. This option allows for easier takeoffs on taildraggers in FBWA mode, and also makes it easier to test auto-takeoff steering handling in FBWA. Setting it to 0 disables this option.

    // @DisplayName: Level flight roll limit
    // @Description: This controls the maximum bank angle in degrees during flight modes where level flight is desired, such as in the final stages of landing, and during auto takeoff. This should be a small angle (such as 5 degrees) to prevent a wing hitting the runway during takeoff or landing. Setting this to zero will completely disable heading hold on auto takeoff and final landing approach.

If that finish line is crossed then the waypoint is considered complete. Note that the navigation controller may decide to turn later than WP_RADIUS before a waypoint, based on how sharp the turn is and the speed of the aircraft. It is safe to set WP_RADIUS much larger than the usual turn radius of your aircaft and the navigation controller will work out when to turn.

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.

  This is a conversion table from old parameter values to new
  parameter names. The startup code looks for saved values of the old
  parameters and will copy them across to the new parameters if the
  new parameter does not yet have a saved value. It then saves the new
  value.

  Note that this works even if the old parameter has been removed. It
  relies on the old k_param index not being removed

  The second column below is the index in the var_info[] table for the
  old object. This should be zero for top level parameters.
