- Explain why timed systematic observations are needed before a radar contact can support a relative-motion, CPA or TCPA forecast.
- Interpret the relative-motion line, CPA geometry and the effect of own-ship movement without confusing relative and true target motion.
- Construct an auditable relative plot from timed ranges and bearings and independently calculate relative speed, CPA and TCPA.
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.
