Century 41 Autopilot

The Century 41 is the advanced digital logic design roll/heading/pitch autopilot with built in VOR/LOC/GS couplers and outputs to drive a single-que, V-Bar flight director system. The basic system consists of the mode programmer, system annunciator, directional and attitude gyros and servos.

Century 41 Autopilot

The Century 41 is a proven concept in autopilot design. Unlike competitive autopilots which are either rate- or position-based, the Century 41 uses both for more precise control and a smoother ride. Other features designed to reduce pilot work-load and fatigue include precisely synchronized pitch attitude and altitude hold modes, a pitch modifier, automatic and manual electric trim, and automated preflight testing. Anticipative VOR/LOC/GS capture automatically compensates for ground speed, intercept angle, wind direction, and distance from the station. "Automatic gain reducing soft enroute VOR tracking" means perfectly mannered station passage.

When using the go-around mode in dealer installed systems, the pilot has only to press the go-around button, clean up the airplane and add go-around power. The autopilot flies to a calibrated pitch up attitude that is set for the single engine safety speed of the airplane and heads to the pilot preset go-around heading.

The Century 41's front panel flight adjustments and custom manufactured cable harness reduce installation and maintenance time and expense.

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