Seven drone exams. One app. Every answer cited.
FAA Part 107, EASA A1/A3 and A2, the UK A2 Certificate of Competency, Transport Canada Basic and Advanced, and CASA. Study once, in one place.
Free to install on iPhone and on Android.
Why the answers can be trusted
Read the reviews of any other app in this category and the same complaint comes back: the answers are wrong. People score full marks in the app and fail the real test. Some apps give two different correct answers to the same question, and the reviewer who spots it gets no reply.
Dronelix shows the rule behind every answer, by section number, and the date that answer was last checked against the current regulation. 14 CFR 107.29. TP 15263 section 4. Regulation (EU) 2019/947. You do not have to trust us. Look it up.
Every question also has a report button. When a report is right, the corrected question travels to your device on its own, without waiting for an app store release. A wrong answer should not survive a review queue.
Inside the app
Reading the chart
Chart symbology is where candidates lose marks and where most apps offer nothing. Solid blue, dashed magenta, a shaded band fading outward: each is a different rule about where you may fly and what you have to ask for first. Dronelix draws every airspace class, airport symbol and obstruction the way the chart draws it, next to what it means for an unmanned flight.
The real format
Mock exams run at the real length, the real time limit and the real pass mark, and practice is weighted the way the authority weights the exam. The FAA changed that weighting in September 2025: regulations is now 48 percent of Part 107 and operations 25, so regulations is what you see most of.
Spaced repetition
Questions come back at the moment before you forget them, not on a fixed rota. What you find hard returns sooner, what you have mastered gets out of the way. Ten minutes a day beats an evening of cramming, and the app tells you when ten minutes has been enough.
One payment
Studying is free on all seven tracks, every explanation and every citation included. One payment of 24.99 dollars adds the full mock exams, forever, and nothing renews. The Part 107 exam itself costs 175 dollars an attempt, with a 14 day wait before you can sit it again.
What each exam looks like
| Track | Where | Questions | To pass |
|---|---|---|---|
| FAA Part 107 | United States | 60 | 70% |
| EASA A1/A3 | European Union | 40 | 75% |
| EASA A2 CofC | European Union | 30 | 75% |
| A2 CofC | United Kingdom | 30 | 75% |
| RPAS Basic | Canada | 35 | 65% |
| RPAS Advanced | Canada | 50 | 80% |
| CASA | Australia | Set by your approved training organisation | |
The fee moves too. Part 107 is 175 US dollars an attempt, a Transport Canada exam is 10.17 Canadian dollars, and a UK A2 course runs from about 49 to 150 pounds depending on the provider. In the European Union each member state sets its own, so the app shows no figure rather than a guess. Confirm the current format and fee with your authority before you book. Rules change, and the authority is the only source that counts.
Free, and what one payment adds
Nothing is locked behind a trial and nothing renews. You can study every track to the end without paying, and the one purchase exists for the part that only matters near the exam date.
- Every practice question, on all seven licence tracks
- The worked explanation and the rule citation behind each answer
- Spaced repetition and a readiness score per subject area
- The sectional symbol reference and the METAR and TAF decoder
- Corrections delivered to the device, without an app update
- Full mock exams on every track, at the real length and clock
- Scored at the real pass mark, the way the authority scores it
- All seven tracks at once, rather than one licence at a time
- Family Sharing, so a second pilot in the house is covered
- It does not renew. There is no subscription to cancel
What a week of study looks like
Open the app, pick your licence, and it starts you on the areas the exam leans on hardest. The first session is deliberately short. It exists to find out what you already know, so the schedule that follows is built on evidence rather than on a syllabus running top to bottom.
After that you get a queue each day, sized to about ten minutes. Questions you miss come back quickly, questions you have answered right three times in a row drift out to a week, then a month. The readiness score on the study screen moves as that happens, per subject area, so a weak spot is visible as a short bar rather than as a bad feeling.
When every area is above the pass mark with room to spare, run a full mock at the real length and the real clock. Most candidates who study daily are ready in two to three weeks. The app is trying to answer one question for you: are you ready to pay for this exam yet.
Questions people ask
Are these the real exam questions?
No, and no study app has them. Every regulator keeps its live question bank closed. Dronelix questions are written from scratch against the published syllabus and the official study guides, which is how every honest study product in this field works. An app claiming to hold the real questions is not telling you the truth.
Which exams does Dronelix cover?
Seven tracks across five authorities: FAA Part 107 in the United States, EASA A1/A3 and EASA A2 in the European Union, the A2 Certificate of Competency in the United Kingdom, Transport Canada Basic and Advanced, and CASA in Australia. You pick a licence when you open the app and can switch at any time without losing progress.
What does Dronelix cost?
Studying is free on all seven tracks, including every explanation and every citation. One payment of 24.99 US dollars adds the full mock exams forever. It is a single purchase, not a subscription, and it does not renew.
What happens when a regulation changes?
A corrected question is pushed to your device without waiting for an app store release, so a wrong answer never has to sit there for a review cycle. Every question also carries the date its content was last checked against the current regulation, and that date is visible while you study.
Does it work without a signal?
Yes. Questions, explanations, citations, the sectional symbol reference and the METAR and TAF decoder are all on the device. You can study on a plane, on a job site or in a field with no bars.
How long does it take to get ready for Part 107?
Most candidates who study daily are ready in two to three weeks. Dronelix shows a readiness score per subject area so you can see whether you are actually there, rather than booking a 175 dollar exam on a hunch.
Is Dronelix on iPhone?
Yes. Dronelix is on the App Store and on Google Play, and it is free to install on both. The same seven licence tracks are there either way, and the lifetime unlock is a single purchase made inside the app.
Dronelix is an independent study app from IOCODO LLC. It is not affiliated with the FAA, EASA, the UK Civil Aviation Authority, Transport Canada or CASA. No study product has the live exam questions, ours included: our questions are written against the published syllabus and the official study guides.
Free to study. One payment for the mock exams.
