- Use a disciplined chartwork routine that turns current source information and observations into a labelled, checkable navigation decision.
- Build and distinguish a dead-reckoning position and an estimated position while carrying their uncertainty forward.
- Assess a visual or transferred fix by the quality, timing and geometry of its observations rather than treating the plotted symbol as proof.
A self-guided revision companion that explains essential concepts, then helps you practise and test them. It supports—but does not replace—recognised instruction, practical training, assessment or certification. Access is a one-time payment, not a subscription.
