There is a number of MAVlink parameters which are changed on the autopilot during operation. Some parameters are set on first vehicle connect, some are set during route upload and command execution. Any mavlink parameter supported by the autopilot can be set on vehicle connect using conf file setting vehicle.ardupilot.parameter

Parameters common for fixed wing and copters

Parameter	Description
GND_ALT_OFFSET	Modified if set_ground_alt_offset is set to yes. See also Set ground altitude offset
MIS_RESTART	Modified during commands AUTO and CONTINUE
RALLY_LIMIT_KM	Used to keep the hash of uploaded route. See also Saving route hash on vehicle	Ardupilot has the following battery-related parameters:
BATT_LOW_VOLT	Battery voltage that triggers a low battery failsafe.
BATT_LOW_MAH	Battery capacity at which the low battery failsafe is triggered.
BATT_FS_LOW_ACT	Low battery failsafe action

Copter parameters

Parameter	Description
BATT_FS_LOW_ACT	Modified if route parameters sets failsafe action on low battery.
FS_EKF_ACTION	Modified if route parameters sets failsafe action on GPS signal loss.
FS_THR_ENABLE	Modified if route parameters sets failsafe action on RC signal loss.
RTL_ALT	Modified if route parameters sets Emergency return altitude.
WP_YAW_BEHAVIOR	Set to 0 if autoheading is set to yes. See also Vehicle heading control
