AeroLens · Beta 0.1.0-beta.1

Aircraft Systems, Explained.

Textbooks teach you the theory. AeroLens helps you see how it works.

Explore the Airbus A320 in 3D, understand aircraft systems through interactive visualizations, and prepare for EASA ATPL examinations and airline technical interviews.

The A320, from the outside in.

Every animation and diagram below is part of the current beta.

CFM56-5B engine cutaway with the combustor lit and airflow particles

ATA 70–80 · CFM56-5B

An engine you can look inside.

Move the thrust lever through its detents and watch the spools, airflow and combustor respond, with a cutaway, a 2D diagram and engineering fundamentals at three levels.

Detailed main landing gear during retraction, with actuators labelled

ATA 32 · Landing gear

Mechanisms in motion.

Extension, retraction and gravity extension, step by step: doors, uplocks, side stays and actuators, synchronised with the hydraulic schematic.

APU schematic during start: starter cranking, combustor burning

ATA 24 · 29 · 36 · 49

Systems you can operate.

Press MASTER SW and START and follow the APU start in the diagram. Connect external power and watch the buses come alive. Hydraulics, fuel, pneumatics, fire, oxygen and doors work the same way, and every change is explained.

Learn · Revise · Practise

From first principles to the interview.

Lessons linked to EASA ATPL learning objectives, spaced-repetition flashcards and technical interview questions with key points and model answers.

Learning modes

One platform. Three ways to learn.

Switch at any time: the same aircraft and the same systems, explained at the depth you need.

Discover how aircraft work.

Explore modern aircraft systems through interactive 3D experiences and clear, beginner-friendly explanations.

For aviation enthusiasts, beginners and future student pilots.

Why AeroLens

Built by a student pilot. Driven by curiosity.

“I’m not just building AeroLens for other pilots. I’m building the learning tool I want to use myself.”

AeroLens is created by a French student pilot who has completed the EASA ATPL theoretical exams and is continuing practical flight training. Seeing real engines and mechanisms made theory click, but not every student has that access. AeroLens aims to make some of that visual learning available to everyone.
