Century 4000 Autopilot

Century Flight Systems understands the real world of the cockpit and knows how to transpose these conditions to reliable hardware. Now it's done in a way to allow each pilot the equipment needed to do the job.

Century 4000

As new requirements arise, functions can be added as desired to the expandable Century 4000.

To begin with, the main frame is the best designed autopilot built today fully worthy of the legacy of Century autopilots. The capture, track, soft-ride, and gust alleviation of this system are unparalleled!

Standard lateral axis features include Heading Hold, NAV intercept and track, fully coupled ILS approaches, localizer back course, VOR approach outbound intercept and track, lateral navigation steering and sequencing including en-route, terminal and approach segments with compatible GPS receivers providing ARINC 429 steering commands.

The pitch axis comes complete with trim prompting, pitch attitude hold, altitude hold, vertical speed select and hold, glideslope capture and track from above or below the glide slope and is fully capable of LPV and LNAV/VNAV approaches with compatible GPS WAAS receivers.

Automatic electric pitch trim, Flight Director or yaw damper expansions may be easily added to the Century 4000.

Options: The NSD slaved or non-slaved HSI system or other compatible HSIs may be substituted for the directional gyro. Altitude preselect and alerter is also available.

Century 4000 Specifications

Basic 2-Axis Trim Prompt

Panel Space 6.35 x 1.5 inches
Weight 8.2 lbs.
Power 1.5 amps nominal @ 14 or 28 VDC
The roll axis channel features continuous roll/nav/voltage monitors, heading hold, heading select, NAV (VOR/RNAV) /LOC/BC/LNV (GPS Steering), anticipative intercept and track, automatic soft track, auto 45-degree intercept, and all angle intercept with HSI.

Pitch channel features altitude hold, attitude command, electronic altitude hold, vertical speed hold, G/S capture and track, proportional pitch trim prompting, control wheel steering, continuous pitch/GS monitors, and automatic pitch synchronization.


Automatic Pitch Trim Expansion

Panel Space No additional required.
Weight 2.7 lbs.
Power 1.1 amps nominal @ 14 or 28 VDC

The autotrim expansion adds automatic electrical pitch trim during autopilot operation and yoke mounted command electric pitch trim.


Flight Director Expansion

Panel Space No additional required.
Weight 0.4 lbs.
Power 0.3 amps @ 14 or 28 VDC
Flight Director
The flight director expansion computes the necessary roll and pitch attitudes needed to intercept and maintain headings, courses, attitudes, and altitudes. These computations are then displayed through the flight director horizon as steering commands, greatly simplifying instrument flight.

Yaw Damper Expansion

Panel Space No additional required.
Weight 2.8 lbs.
Power 1.9 amps @ 14 or 28 VDC

Yaw Damper
The Yaw Damper is a subsystem which enhances directional stability by reducing short-term oscillations in the yaw axis, therefore enhancing passenger comfort. In addition, it maintains coordinated flight during turns. The yaw damper is activated with autopilot engagement but may be operated independently. This expansion may be added to any package.
