Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'plain sailing' (лёгкое дело). 'Plane sailing' is технический/исторический термин.
- Beware of false cognate 'plane' (самолёт). Here it relates to 'plane geometry' (плоскость).
- The phrase is often a 'false friend' for the common idiom.
Common Mistakes
- Misspelling as 'plain sailing' when referring to the technical term.
- Using 'plane sailing' in everyday speech when 'plain sailing' is meant.
- Pronouncing 'plane' as /pleɪn/ (like airplane) instead of the correct /pleɪn/ (same pronunciation, but different meaning).

It comes from 'plane' as in a flat geometric surface, referring to the assumption of a flat Earth for the calculation, not from 'airplane'.
Not in practical ocean navigation, which uses spherical models and GPS. It is only of historical and theoretical interest.
It would be considered non-standard or a malapropism by most listeners. You should use the idiom 'plain sailing' for that meaning.
