this will reduce confusion when searching for FLIGHT_LAND_* and you get a bunch of takeoff related hits. It will also make more sense when the landing library fully manages the FLIGHT_LAND stage entirely because it will not mange FLIGHT_LAND_ABORT
This should fix CID 91386.
Before removing the 'if', I checked the log to confirm that both branch
didn't end-up being equal by mistake in some commit. But it looks like
the file was added in the project this way.
during the first part of a takeoff when we have not yet reached the
target airspeed this forces the throttle to maximum. This fixes a case
where the throttle may drop too low during the first part of takeoff
and lead to a stall.
recent fixes in Plane have made the stage more accurate so exceptions/hacks are no longer needed to differentiate between knowing if executing NAV_LAND vs being in stage_approach.
we now can exit an underspeed condition if we stay above min speed for
3 seconds and also reach 15% above min speed. This prevents a problem
with the thrust line causing downpitch leading to a crash due to too
much throttle
- throttle slew rate was using % full range including the negative range (-100 to +100 instead of 0 to 100) which meant it was faster
- throttle integrator windup limit was higher than normal because it's a porportional to throttle max - min but that makes no sense when min is negative causing larger limits
// @Description: This is the damping gain for the pitch demand loop. Increase to add damping to correct for oscillations in speed and height. If set to 0 then TECS_PTCH_DAMP will be used instead.
+ // @Description: This is the damping gain for the throttle demand loop during and auto-landing. Same as TECS_THR_DAMP but only in effect during an auto-land. Increase to add damping to correct for oscillations in speed and height. When set to 0 landing throttle damp is controlled by TECS_THR_DAMP.
// @Description: When zero, the flare sink rate (TECS_LAND_SINK) is a fixed sink demand. With this enabled the flare sinkrate will increase/decrease the flare sink demand as you get further beyond the LAND waypoint. Has no effect before the waypoint. This value is added to TECS_LAND_SINK proportional to distance traveled after wp. With an increasing sink rate you can still land in a given distance if you're traveling too fast and cruise passed the land point. A positive value will force the plane to land sooner proportional to distance passed land point. A negative number will tell the plane to slowly climb allowing for a pitched-up stall landing. Recommend 0.2 as initial value.
