Spotter community
Photos aviators upload in the app — approved, curated, every shot links to that aircraft's profile. No stock photos, all real.

Approved photos only, usernames only — never IDs or e-mail addresses. Same privacy as the in-app leaderboard.
The flightbag
From live radar to a crosswind calculator — the tools that matter in the cockpit and on the ground. All in the app, free for now.

Act II · The Academy
The full EASA syllabus, an AI instructor that answers your question, spaced repetition that reviews exactly when you're about to forget, and real mock exams. For PPL(A) & PPL(H), in German and English.
What sets us apart
Other PPL tools are question databases for rote learning. We build the theory teacher you rarely meet at flight school: personal, patient, always available — tailored to each of the six pathways (PPL-H + PPL-A × CH · DE · AT).
01 · AI-FI Tutor
You type a question — the tutor doesn't answer with a dictionary entry but guides you Socratically to the solution. Patient, on your phone, whenever you want.
02 · Smart Repetition
FSRS-4.5 schedules your reviews automatically. Hard stuff you see often, easy stuff rarely — you retain more and save real hours.
03 · Mock Exam
16 questions, 30 minutes, 75 % to pass. Own questions in ECQB style (European Central Question Bank). After scoring, AI-FI debriefs each wrong answer Socratically.
Pro: unlimited + AI-FI debrief
EASA syllabus 1:1, plus country-specific cards for BAZL (CH), LBA (DE) and Austro Control (AT). Alpine MET (Föhn, Bise, alpine crossings) as bonus. PPL(H) and PPL(A) curated separately — no generic drill.
Today's cards cached. Reviews sync when you're back online. Installable to the home screen — no app store needed.
This is what a card looks like
Cards that fail our second-pass QA get flagged, return to the editor, go through the CFI(H) review, and only then land with you. Pure drilling isn't enough — you have to understand it for it to stick.
Translational lift falls away.
Hovering into wind, the rotor effectively has forward airflow — tip vortices and your own downwash get blown away, the rotor works more efficiently. When the wind drops, the heli sinks back into its own downwash and needs more power for the same lift.
Why
From about 12–15 kt of relative airflow (combined wind and forward speed), Effective Translational Lift sets in. In a stationary hover into wind you reach this threshold without forward speed — and lose it again as soon as the wind subsides.
Common pitfall
Confusing it with Vortex Ring State (VRS). VRS requires descent + low forward speed + power applied. Here you only lose ETL — VRS is a separate, far more dangerous phenomenon.
Licence × Country
Pick your licence and country — the syllabus adjusts automatically. Local regulators come as a dedicated layer on top of the global EASA core.
Every pathway covers the full EASA syllabus (9 subjects, 1,643 learning objectives). The country layer adds regulatory and geographical specifics — no teaching BAZL rules to pilots in Frankfurt.

Pricing
Pilot training quickly costs a five-figure sum. Theory preparation that actually works shouldn't fail at the workload. Licence × Country (PPL-H + PPL-A · CH/DE/AT) is included in every tier.
