🔍 Key Concepts

• Set and drift of current – drift is the distance the current moves you from your DR track; set is the direction it moves you • Difference between DR (dead reckoning) position, fix, and EP (estimated position) • How current is actually determined on a plot: comparing the DR position (no current) to the observed position (with current) over a known time interval

💭 Think About

• Look at each choice and ask: does this describe how navigators really measure or use current on a standard plotting sheet? • Which position pair do you use to determine current: DR-to-fix, DR-to-EP, or something else? Why? • If you have found current once, would a prudent navigator ignore it for later plotting, or would they carry it forward (with caution)?

✅ Before You Answer

• For each option, verify whether it uses the correct pair of positions (simultaneous DR and fix vs DR and EP) to determine set and drift • Check your definition: drift = distance of the current’s effect over a known time, not a rate unless divided by time • Ask yourself if a statement that calls current an "unknown variable" matches good navigation practice once you’ve just measured it on the chart

Question 1 of 20

Which statement concerning current is TRUE?

The distance between a simultaneous DR position and fix is equal to the drift of the current.

The drift of the current should be averaged out on a one-hour basis.

After the current is determined, it should not be used for further plotting because it is an unknown variable.

Current can be determined by measuring the direction and distance between simultaneous EP and DR positions.
