Function: A-320 autopilot test file Note: this file represents a test only of the new autopilot
setup in JSBSim. The same components used in the FCS
can also be used in the autopilot section. There are
some new FCS input and output identifiers directly
related to the autopilot: ap/elevator_cmd,
ap/aileron_cmd,
ap/attitude_hold,
ap/altitude_hold,
ap/heading_hold,
ap/altitude_setpoint,
ap/heading_setpoint -->

--> <!-- Altitude hold --> <!-- The Altitude Error component below computes the altitude error, subtracting
the desired altitude (altitude_setpoint) from the actual altitude above sea
level (_not_ Above Ground Level). This error signal is interpreted as an
hdot command (hdot is time rate of change of altitude, or rate of climb). As
such it is limited to a maximum absolute value of 12 fps here (720 fpm). The
maximum achievable climb rate depends on altitude. The commanded climb rate
is scheduled in the HDot Command component, below. For the given altitude
(left column in the table), the commanded maaximum climb rate divided by 100
is given in the right column.

Dependent on altitude, the lagged (and limited) altitude error is multipled

the desired climb rate is 100 percent of maximum and the current altitude is
1000.0 ft., then the output from this component would be 24.5 ft. sec.
The equation representing climb rate for the C-310 is:
取决于高度，滞后（和有限）高度误差乘以从下面的函数确定的增益。 该组件的输出是以英尺/秒为单位的绝对预期爬升率。 例如，如果所需爬升率为最大值的100％且当前海拔高度为1000.0英尺，则此组件的输出将为24.5英尺秒。
表示C-310爬升率的公式为：
ROC（英尺/秒）= 25.7 - h / 833.33
