Your dream of flying starts here. Prepare thoroughly for the DLR test and pass it on your first try. We are the most comprehensive preparation for the DLR aptitude test for aspiring pilots—featuring all ten sections of the DLR test, AI-powered coaching, and a training plan that adapts to you. Not the other way around. Whether your test date is in three weeks or six months: The app shows you what to focus on every day, identifies your weaknesses, and brings you step by step to the level you need to pass. ALL 10 TEST TYPES – NO GAPS Practice KRN, RMS, WFG, TVT, VMC, ENS, SKT, OWT, PPT, and MIC — the question formats you’ll encounter on test day. Each practice session is algorithmically generated. Memorization? Out of the question. And the TVT question bank also prepares you perfectly for this — with over 900 questions from seven areas (Mechanics, Thermodynamics, Electricity, Optics, Waves, General Physics, and General Engineering), including explanations. FLIGHTBRAIN – YOUR AI CO-PILOT After each practice run, our FlightBrain AI analyzes your results: What went well, where are you losing points, and what should you practice next. You’ll also receive recommendations (available only in the web app) – based on your actual practice data. YOUR PERSONAL TRAINING PLAN Enter your test date, and the app creates a training plan tailored to your pace and progress. Every day, you’ll know exactly which test types are coming up and in what order. Includes weekly goals and calendar sync. And because only you know how you learn, the plan adapts to your learning progress and pace at all times. CLEARANCE SCORE Your Clearance Score shows you at a glance how close you are to passing—calculated from over 40 cognitive skills tested in the actual exam. CREW & COMMUNITY You’ll be automatically assigned to a crew—made up of other candidates with similar test dates. Exchange ideas in the forum, share results, and don’t study alone. PASS GUARANTEE We’re confident that you’ll pass with our app. If not: With a minimum 3-month subscription and 100 completed practice tests, we’ll extend your access for another 3 months at no cost. 6 DIFFICULTY LEVELS PER TEST You start at an accessible level. As soon as you consistently meet the criteria for a level, the difficulty automatically increases—with more tasks, shorter time limits, and more complex challenges. This ensures you’re always training at exactly the right level. DLR SIMULATION Complete all tests in succession—with set breaks and under time pressure. Just like on the actual test day. Afterward, FlightBrain evaluates your overall performance (available only in the web app). STRENGTHS AND WEAKNESSES ANALYSIS You’ll see exactly which skills are strong, where you’re losing points, and at what time of day you perform best. FOCUS TRAINING Target your weaknesses—the app generates exercises focused specifically on the skill that’s holding you back. Your test date is set. Now your preparation is too.
