in Table 1-24 and should only be adjusted after studying the descriptions to
properly understand their effect on the pitch servo.
Pitch Servo Gain
The pitch servo gain settings should be configured only after the pitch/roll servo max
torque and servo gains have been set per the preceding pages.
The minimum maximum airspeed limit entries set the limits of the autopilot vertical
authority. The autopilot will limit the pitch control to stay within these airspeed limits.
The vertical speed gain entry is one of the most important gains in the system since
it controls the behavior of the VNAV, ALT, and VS modes and also largely determines
how well the plane flies approaches with vertical guidance.
The vertical speed gain is adjusted in a very similar manner to the pitch servo gain.
Engage the autopilot in ROL/VS mode in level flight (vertical speed approximately
zero).
Adjust the vertical speed gain so that the aircraft properly responds to the VS
guidance from the flight director.
1)
Overpower the autopilot to fly away from the current flight director
commanded vertical speed.
2)
Release the controls and monitor the autopilot response and closure back
to the commanded vertical speed.
3)
Set the vertical speed gain higher to make the autopilot more aggressive if
it feels “lazy” or not as responsive as desired.
4)
Set the vertical speed gain lower to make the autopilot less aggressive if
the control is too “harsh” or more responsive than desired.
The vertical acceleration gain can often be left set at 1.00, but can be used to
improve altitude captures when climbing or descending in VS or VNAV mode.
1)
Climb to an altitude target in VS mode and observe the altitude capture.
2)
Set the vertical acceleration gain higher if the aircraft objectionably
overshoots the altitude target before leveling off at the correct altitude.
3)
Set the vertical acceleration gain lower if the aircraft objectionably
undershoots the altitude target before leveling off at the correct altitude.
Similar to the vertical speed gain, the airspeed gain can be used to improve airspeed
hold performance when needed.
