The day that decides your dream of the cockpit is getting closer. With DLR Test Trainer you walk in prepared, not nervous. The app trains all ten computer-based test types of the DLR pilot aptitude test (Stage 1), used by SWISS and the Lufthansa Group with the European Flight Academy, among others. Every task is freshly generated, so you train the skill, not the answers. The 10 test types • SKT Triangle test: rules under time pressure • VMC Visual memory: n-back with shapes and colors • RMS Running memory: enter heard digits backwards • KRN Mental arithmetic: tasks you only hear, never see • OWT Instrument reading: nine gauges in a few seconds • PPT Cube folding: which cube matches the net? • WFG Path figures: count the turns, crossings included • TVT Technical comprehension • PHY Physics • ENS English Know where you stand • Placement test: five short exercises in about 5 minutes show your strengths, your focus modules and a recommended starting level. • Compare yourself: see how your first placement test stacks up against other applicants, anonymous and only if you want. • Test readiness from 0 to 100: one number for your level, with the change since last week and your biggest lever. • Target traffic lights per module: green, amber or red against benchmarks from candidate reports. • Error analysis after every session: concrete hints on where you lose points. • Adaptive levels: three greens in a row and the app suggests the next level. Stay on track • Countdown to your test date, daily goal and streak with streak freeze • XP, ranks and 23 achievements • Reminders that fit your day Pro • All 10 modules without limits • Exam simulation: all modules back to back in the order of the test day, full (about 60 minutes) or compact (about 30 minutes), with a report • Training plan up to your test date and history charts Pro is available as a monthly subscription (cancel any time) or a one-time lifetime purchase. Free • Cube folding, path figures, technical comprehension and English free forever • Try each of the other six modules three times for free • Placement test, test readiness, error analysis and level suggestions included For other pilot aptitude tests too Mental arithmetic, spatial reasoning, memory, concentration, technical knowledge, physics and English are part of almost every pilot aptitude test, such as SPHAIR, COMPASS or military pilot selection. Private and offline No account, no ads. Your training data stays on your device, with export and import for a new device. Only if you choose to compare yourself with others is the result of your first placement test sent anonymously. In 10 languages, on phone and tablet. Note DLR Test Trainer is an independent app and is not affiliated with the German Aerospace Center (DLR). It contains no original test items, only its own recreations of the test formats.

ATC Aptitude Prep

Passing isn't the same as getting hired. The FAA's published pass mark for its air traffic controller aptitude test is 70%. But it sorts everyone who passes into score bands — and since 2018 it has selected candidates only from the top two: Well Qualified (85–89%) and Best Qualified (90%+). Thousands of people pass every year and are never referred. Most prep aims at the pass. ATC Aptitude Prep aims at the band. WHAT YOU GET • 2,100 original practice questions across the nine skills every ATC selection battery tests • Six interactive timed drills, generated fresh every run — nothing to memorise, only skill to build • A full-length practice battery: 100 questions in 100 minutes, scored into the real bands • A worked explanation for every single answer — the method, not just the letter • Spaced repetition that resurfaces what you got wrong, right before you'd forget it • A readiness score and per-skill mastery, so you always know what to work on tonight • Flashcards and a glossary: ICAO phonetics, headings, Zulu time, flight levels, separation • Works fully offline. No account. No sign-in. No ads. No tracking. THE NINE SKILLS Spatial reasoning & 3D orientation Ā· Numerical, time & distance Ā· Pattern recognition & sequences Ā· Working memory Ā· Multitasking & divided attention Ā· Logical reasoning & analogies Ā· Situational judgment & prioritisation Ā· Scanning & visual search Ā· ATC knowledge basics The FAA's assessment, EUROCONTROL FEAST, NATS, NAV CANADA and Airservices Australia were developed independently — and all converge on these same constructs. None requires prior aviation knowledge. They measure aptitude, and aptitude is trainable. THE SIX DRILLS Heading & Turn Ā· Radar Scan Ā· Clearance Memory Ā· Dual-Task Ā· Sequence Sprint Ā· Time to Conflict Every round is generated fresh, so you can run them forever. Speed is scored on every real battery, not just accuracy — the questions teach the method, the drills build the speed. HONESTY ABOUT WHAT THIS IS No ATC selection battery publishes its test items — they are proprietary and only ever seen in a supervised test centre. Nobody can sell you "the real questions." Every question, drill and explanation here is an original work, written from public descriptions of the skills these tests measure. PURCHASE REQUIRED ATC Aptitude Prep is free to download, and a purchase is required to use it — there is no free tier. All three plans unlock everything: • Monthly — $9.99 per month, auto-renewing • Annual — $49.99 per year (about $4.17/month) with a 3-DAY FREE TRIAL, auto-renewing • Lifetime — $99.99 one-time purchase, never renews Payment is charged to your Apple Account at confirmation of purchase.
