The second pillar of COMPASS is neuro-sensomotoric: hands-on-controls tasks that measure coordination, task management and reaction under load. These are the subtests candidates tend to worry about most, because they cannot be crammed the night before — the underlying skills build gradually with repeated exposure.
What candidates describe
Control and tracking: flying a target or keeping a marker on a path using joystick-style inputs, reported to sometimes combine hand and foot (rudder-pedal style) control simultaneously.
Task management and multitasking: the Task Manager subtest, described in the official test material as two concurrent tasks on one keyboard — entering new altitude, heading and speed values into the autopilot accurately while cancelling red alert signals that come on at irregular intervals, with marks only for alerts cancelled within three seconds.
Reaction and attention: responding quickly and correctly to changing stimuli, choosing the right response among several options, and sustaining concentration through long, monotonous stretches without letting accuracy slip.
How to prepare
This is where early, spaced practice pays off most. The Hand-Eye-Foot Coordination Test and Path Following Test build the coordination base; the Task Manager game reproduces the COMPASS two-task screen itself — autopilot data entry plus the three-second alert rule, on one shared keyboard exactly as the real subtest runs; the Multitasking Test adds the tracking-under-load version of the same skill; and the Complex Choice Reaction Test, the Determination Test and the Vigilance Test exercises cover the reaction and vigilance family, with the Instrument Monitoring Test adding the gauge-watching version of the same vigilance. Practise in short daily blocks over several weeks rather than marathon sessions — motor learning consolidates between sessions, not during them — and watch your trend lines to confirm the curve is still rising before test day.
