Autopilot night watch control drill
Practise an autopilot night watch control drill: locate standby, read the active mode and find alarm controls from the position you actually use on watch.
An autopilot night-watch drill checks whether each watchkeeper can identify the active mode, find manual takeover and interpret an alarm from the normal helm position. Prepare the controls in daylight, then review their visibility after dark in suitable conditions. The aim is a clear operating arrangement, not a test of how well someone performs while exhausted.
Make the night setup a daylight job. Stand at the normal watch position, dim each screen and identify the active mode without opening a menu. Ask the next watchkeeper to show the standby control and explain the next navigation event. If the briefing needs a long explanation while everyone is rested, simplify the arrangement before departure. Keep the operating card specific to the installation, including any mechanical release. The useful test is whether another competent crew member can understand the arrangement, rather than whether its owner remembers every shortcut.
Takeaway
Check visibility from the actual watch position
A control that is readable while standing beside the wheel may be obscured when seated, wearing wet-weather clothing or moving between helm stations. Review the active mode, target and alarm indication from those positions. Include chartplotter brightness and cockpit lighting so one bright screen does not undermine the rest of the night setup.
Ask a second regular watchkeeper to explain the display. Record ambiguous labels or controls that need a menu search, and resolve those issues with the installer or instructor. A laminated card can identify the supported takeover procedure, but should not replace practical familiarisation.
Record unresolved night-watch checks
Write down which displays were checked, who completed the demonstration and whether alarm audibility was verified using a supported test. If a remote was included, record where it was tested and the fallback when it is unavailable.
Repeat the review after a display is moved, software changes the interface or a new crew member joins. Keep an unresolved item open rather than marking it complete because another person knows the answer.
Frequently asked questions
Should the drill be carried out while tired?
No. Establish the procedure while rested and in suitable conditions. Fatigue is something the passage plan must manage, not a condition to create for a training exercise.
Does dimming the chartplotter dim every autopilot control?
Do not assume so. Check each installed display and controller; brightness settings and network behaviour depend on the equipment.
