Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'лететь-тестировать'. Use 'испытывать в полёте' or 'проводить лётные испытания'.
Common Mistakes
- Using it intransitively (e.g., 'The plane flight-tested' is wrong). Correct: 'They flight-tested the plane.'
- Confusing the verb 'flight-test' with the noun 'flight test'.
- Misspelling as one word 'flighttest'.
