Master the acoustic mental math aptitude tests used by major international airlines for pilot screening. Pilot Mental Math is a specialized utility designed to simulate the high-pressure environment of auditory calculation assessments. Unlike standard math apps, this tool focuses on the specific cognitive load of listening to equations, retaining numbers in working memory, and calculating under strict time constraints. It is built specifically for candidates preparing for pilot selection processes (screening) at major airlines and flight schools. • Multi-language support: Train in English, German, French, Spanish, Portuguese, Russian, Chinese, Arabic, or Hindi to match the language of your airline assessment. CORE FEATURES • Acoustic Simulation: Train your ear. Questions are spoken, not just displayed, forcing you to rely on auditory memory. • Adaptive Difficulty: Four distinct modes ranging from "Easy" (mechanics warmup) to "Hard" (overload training) and "Drills" (rapid-fire). • Custom Flight Path: Configure your own training parameters. Select specific operations (e.g., percentages, squares, roots, navigation headings) and adjust number ranges to target your weaknesses. • Exam Mode: Simulates test day conditions. The visual timer is hidden, and audio cues warn you when time is running out. • Performance Tracking: Detailed flight logs track your accuracy and speed over time. Identify trends and monitor your improvement. TRAINING MODES • Easy: Focus on the mechanics of calculation without time pressure. • Medium: Standard difficulty level for general aptitude maintenance. • Hard: High-load training designed to stretch your working memory capacity. • Drills: High-speed, low-complexity questions (3-5 seconds) to build instinctive number sense. MATH OPERATIONS • Basic Arithmetic (Add, Subtract, Multiply, Divide) • Advanced Operators (Squares, Cubes, Square Roots) • Percentage Calculations • Navigation Headings (Reciprocals and Turns) DISCLAIMER This application is an independent training tool. It is NOT affiliated with, endorsed by, sponsored by, or connected to any airline, aviation training organization, or assessment center. Use of this app is for educational purposes only. Prepare effectively. Good luck and Happy Landings. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

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. The MIC multitasking test with joystick cannot be trained in the app. No app can guarantee that you pass.
