How is the knowledge hub different from exam prep?

The hub covers regulations, maps, manufacturer guides and calculators. Exam practice lives in the learning area with the question bank and simulator.

Where is the FPV build configurator?

Open Guides → FPV & custom, or scroll to the supplementary FPV tools block at the bottom of Tools. Use the learning area for exam practice.

Are DJI, FPV and enterprise drones covered separately?

Yes. Pick a guide segment — consumer drones, FPV and custom builds, commercial platforms or software — so content does not mix.

Do guides follow EASA rules?

Articles are aligned with EASA Part-UAS and national authority practice, with review dates and links to official sources on pillar hubs.

Where should I start if I do not know which licence I need?

Start with the eligibility test or the licence guide — both are linked from the Start here section.

How do I study by exam topic?

The hub home lists ten syllabus pillars (law, safety, airspace, meteorology and more). Open the guide for your weakest area first.

Do guides cover both A2 and STS prep?

Yes — the licence segment covers A1/A3, A2 and STS. FPV and manufacturer guides are supplementary; use the learning area simulator for exam practice.

Which official sources do you use?

EASA Part-UAS, national authority catalogues and official UTM maps. Pillar articles include review dates and links to primary documents.

Are document templates available?

Yes — flight log, checklist, risk assessment, GDPR consent and more under /knowledge-hub/templates. Download fillable PDF forms with text fields and checkboxes.

What is in Faults & software?

Technical reference after licensing — firmware and fault guides.

Where are all drone fault guides?

In the knowledge hub troubleshooting encyclopedia — 42 step-by-step articles: GPS, battery, FPV, ESC, gimbal.

Which software for FPV?

Betaflight for acro; INAV for GPS return; DJI Fly for ready-to-fly; ExpressLRS for RC link.

Bojājumi un programmatūra

Tehniskā uzziņa pēc licences — firmware un bojājumu ceļveži.
