* Previously, the ELEVON_REVERSE parameter was equivelant in function to the
ELEVON_CH1_REVERSE parameter. These parameter values are found in
g.reverse_elevons and g.reverse_ch1_elevon, and used to map to the radio_out
channels in ArduPlane/Attitude.pde
* It seems the author's intent was for ELEVON_REVERSE to change the sign for
the combination of pitch & roll into ch1 & ch2, as there are already
parameters which change just the sign of ch1 and just the sign of ch2.
* Discovered this bug because I happened to build an elevon airframe which was
not possible to setup with the existing ELEVON_ and RCn_REV parameters.
* This will break existing elevon setups if the user used ELEVON_REVERSE
instead of ELEVON_CH1_REVERSE, since they were previously interchangable.
setting ARSPD_ENABLE to 1 and ARSPD_USE to 0 allows the airspeed
sensor to be initialised and logged without it being used for flight
control. This is very useful when initially testing an airspeed sensor
in a new plane. It also makes it possible to enable/disable the use of
the airspeed sensor during a flight at any time.
This patch will boost the target airspeed as necessary to keep the ground speed above a parameter value - param_min_groundspeed. Airspeed is still limited to FBW-max. Setting min_groundspeed to zero (default) disables the feature.
The g_rc_function[RC_Channel_aux::k_flap_auto] ptr came out as NULL
during one HIL run on a desktop CPU, which led to ArduPlane
crashing. I am not yet sure if this can happen in real flight, but I
think the NULL check is worthwhile to be sure.
Add code to disable throttle if we are on the ground and in FBW_B or higher. We believe we are on the ground if speed < 5 and alt < 5. Also check that we are not trying to perform a takeoff.
