Learn how to use the DC-3 autopilot in MSFS 2024, including Sperry controls, heading and pitch hold, safe disconnects and common fixes.
In Microsoft Flight Simulator 2024's DC-3, trim the aircraft for steady flight, synchronise the directional gyro, centre the Sperry Gyropilot's turn and pitch controls, then engage its autopilot or servo control. It holds heading and pitch attitude, not a programmed route or reliably captured altitude; throttle, mixture, propellers, trim and descent planning remain manual.
Which DC-3 autopilot is this procedure for?
These steps apply to the included DC-3's classic Sperry-style Gyropilot rather than a third-party aircraft or retrofit panel with a digital autopilot controller. Look around the lower centre panel and forward pedestal for the Gyropilot controls, using cockpit tooltips to confirm each control.
If your aircraft has a digital controller with separate HDG, NAV and ALT buttons, follow the labelled modes instead; our basic MSFS autopilot operating sequence explains that type of system. The classic DC-3 installation is much simpler:
| Control | Practical function | What it does not do |
|---|---|---|
| Directional gyro | Provides the heading reference after being synchronised with the magnetic compass | Enter or follow a flight plan |
| Turn or aileron control | Commands a gentle turn; centre it again on the new heading | Automatically intercept a GPS course |
| Pitch or elevator control | Changes the pitch attitude held by the system | Capture a selected altitude or vertical speed |
| Autopilot or servo control | Couples the Gyropilot to the flight controls | Control throttles, propellers or mixtures |
How do you engage the DC-3 autopilot?
Engage the DC-3 autopilot only after establishing a stable, trimmed flight condition at a safe height.
- Complete the aircraft setup. Both engines should be running normally, generators and required systems should be online, and the gyro instruments should have settled. If starting from an unpowered cockpit, first complete the DC-3 cold-and-dark start and systems setup.
- Set and balance engine power. Match the engines closely, establish the intended cruise or climb power and let the airspeed settle. Unequal power makes the DC-3 yaw and can leave the autopilot fighting a problem it was not designed to solve.
- Trim by hand. Hold the required attitude and remove most control pressure with pitch, rudder and aileron trim as applicable. Do not engage while climbing steeply, turning or correcting a large trim error.
- Synchronise the directional gyro. While flying straight and steadily, compare it with the magnetic compass and correct the gyro heading. Do this before coupling the autopilot; moving the heading reference after engagement may command an unwanted turn.
- Centre the Gyropilot controls. Put the turn control at neutral and ensure the pitch control is not demanding a large attitude change. A displaced controller is a common cause of an immediate roll or pitch movement.
- Engage the system. Operate the autopilot master or servo control while keeping a hand on the flight controls. If the panel models separate axis or servo switches, couple the required lateral and longitudinal channels as labelled. Some variants expose one master control instead.
- Change heading gently. Ease the turn control left or right, monitor the directional gyro and return the control towards centre before reaching the desired heading so the bank can unwind. With the control centred, the Gyropilot should stabilise the new heading.
- Adjust pitch in small amounts. Move the pitch or elevator control one increment at a time and wait for the aircraft to respond. Protect the airspeed with manual power changes; commanding more nose-up attitude without adding power will slow the aircraft.
Monitor the aircraft rather than leaving it unattended. The directional gyro can drift, power can become unequal and a fixed pitch attitude will not maintain one altitude as speed, loading or weather changes.
Can the DC-3 autopilot follow GPS or hold altitude?
The classic Sperry Gyropilot cannot follow a GPS flight plan or capture a selected altitude. It stabilises heading and pitch attitude, so a well-trimmed DC-3 may remain near the same altitude in smooth air, but that is not true barometric altitude hold.
A moving map or GPS fitted to a retrofit panel does not automatically provide steering. NAV tracking exists only when that particular panel and aircraft implementation present an explicit coupled NAV mode.
Generic MSFS bindings may activate simulator-level NAV or ALT functions even when the cockpit has no matching control. We recommend avoiding those hidden modes with the classic panel: they can produce unexplained turns or pitch changes and do not represent how the Sperry unit works.
Why does the DC-3 turn, pitch or weave after engagement?
Sudden movement after engagement usually means the aircraft was out of trim, a Gyropilot control was displaced or another input is conflicting with the autopilot.
- Immediate hard turn: centre the turn control, check that the heading reference was not moved and confirm no generic HDG or NAV binding is active.
- Sharp climb or descent: disconnect, stabilise and retrim manually, then check the position of the pitch control before trying again.
- Slow weaving: increase from an excessively low airspeed, match engine power and avoid making repeated large turn-control corrections.
- No response: verify aircraft power and gyro operation, then confirm that the master and any separately modelled servo channels are engaged.
- Repeated disconnection: look for duplicate autopilot-master or disconnect assignments, a noisy hardware switch, or an assistance feature issuing control commands.
For faults that persist across aircraft, work through our autopilot power, trim and control-binding checks before reinstalling or resetting the DC-3.
How should you disconnect the DC-3 autopilot?
Take the controls, operate the cockpit autopilot or servo disconnect, and confirm that every coupled axis is off before manoeuvring. Expect some control pressure if the aeroplane has drifted out of trim while the Gyropilot was engaged.
Disconnect well before landing, during strong turbulence, after a major power change or whenever the system begins making corrections you do not understand. The classic DC-3 has no autothrottle or autoland capability, and the final approach and landing remain manual.
