Padpilot EASA ATPL Gas Turbines Learning Core Padpilot Learning Cores are the new way to learn ATPL theory without breaking a sweat! This Gas Turbines learning core is the first of what will eventually be a whole series of cores covering critical parts of each ATPL subject area. This app helps you to understand the design, construction and function of a modern triple spool gas turbine engine. It doesn’t (yet) teach you everything you need to know for the EASA exam (you still need to refer to our ATPL book) but it does build a solid foundation of the basics. It’s also a fabulous learning tool for current airline pilots or engineers who wish to refresh their gas turbine knowledge. Later versions of this core will include more elements illustrating, for example, detailed gas flow and gas turbine theory. Self-test EASA style questions are also coming soon. At the heart of the learning core is a 3D model gas turbine engine based on the Rolls Royce Trent 1000. You can move it around any axis, show and hide individual components and animate some of the main elements such as the individual spools, the thrust reversers and the variable inlet guide vanes. Tapping on individual components reveals a pop-up dialogue box which summarises the design and construction of the item. Where appropriate dialogue boxes also describe the most commonly associated threats or errors. Unique Padpilot navigation wheels let you quickly strip and re-build the engine, or identify by colour each of the three spools. If you need to take a break from text-heavy learning, then Padpilot learning cores are the way to go.
Pilot Mental Math
This app simulates acoustic mental math tests used by airlines for pilot screening. It focuses on auditory memory and calculation under time pressure, offering adaptive difficulty and custom training parameters.
- Acoustic simulation of spoken equations
- Adaptive difficulty levels
- Customizable training parameters
- Exam mode with hidden timer
- Performance tracking and analytics
- Multiple language support

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/
