DRONELINGO

How we build our content — sources and methodology

dronelingo is an independent prep tool for the EASA A1/A3 exam. Our credibility comes from method, not from claims — so here is exactly how the lessons, practice questions, and mock exams are made, and how you can check it yourself.

Only public, official sources

Everything is built from primary, publicly available regulation:

  • Regulation (EU) 2019/947 (consolidated 2022-04-04)
  • Regulation (EU) 2019/945
  • the EASA Easy Access Rules for UAS (2024-07)
  • the public CAA Latvia drone site, droni.caa.gov.lv

The full source library is open on our regulations page. We do not paraphrase from memory: each claim is traced back to the document it comes from.

Every question is cited

Every practice and exam question carries a reference to the exact rule it tests — for example, Reg 2019/947 Art. UAS.OPEN.060. That reference is shown to you on each question review and on your exam result, next to the explanation. Nothing rests on "trust us"; you can follow the citation to the source.

We do not sell leaked or "official" exam questions

The official CAA Latvia exam bank is not public. We do not have it and we do not claim to. Our questions are written from the public regulation and then cited, so they teach the same material the exam is built on without pretending to be a copy of it. Anyone selling "the real exam answers" should be treated as a warning sign, not a shortcut.

Understanding over memorization

The goal is to pass the real exam on your own knowledge, not to memorize a leaked list. Practice uses spaced repetition. Every answer comes with an explanation and the reasoning behind the wrong options, and the mock exam mirrors the real 40-question format. You learn why an answer is correct, which is what actually holds up on exam day and in the air.

Four languages, editor-reviewed

Lessons, questions, and explanations exist in Latvian, English, Russian, and Ukrainian. Each language version is reviewed for meaning, terminology, and readability, and the same cited source stands behind every locale.

What we are, and what we are not

dronelingo prepares you; it does not certify you. The official course and exam both live at e.caa.gov.lv. We are not affiliated with CAA Latvia or EASA. If anything here ever drifts from the current rules, the source library and the FAQ are where we keep that honest.
