ATPL question bank alternative
A Padpilot alternative for EASA ATPL theory study
Looking for an alternative to Padpilot? Welcome to SkyStudy. The two solve different parts of ATPL theory: Padpilot is best known for its interactive theory books, while SkyStudy is an independent EASA ATPL question bank with 31,032 questions across every subject, and the bank is free to use while we are in beta. Below is an honest comparison so you can decide what fits your study.
The question bank is free during the beta, no card required. The demo runs without an account.

What Padpilot is known for
Padpilot is a well-established publisher of digital ATPL theory learning materials. As listed on padpilot.com in July 2026, it offers interactive EASA ATPL(A) and ATPL(H) theory books sold per subject or as a complete-course subscription covering all 13 subjects, an AI-powered study assistant called the Padpilot Briefing Room, and materials used by more than 180 partner training organisations, accessible on Apple, Android and desktop devices.
SkyStudy vs Padpilot, side by side
Compared on objective, verifiable points. Competitor figures are as listed on their own site or store in July 2026 and cover different scopes and editions, so they are not strictly like for like.

A SkyStudy question, in full
A question count tells you nothing about whether the questions are any good. This one is taken straight from the Principles of Flight (081) set, answer and reasoning included.
Principles of Flight (081)
The relationship between MCRIT and MDD is:
- MDD is always higher than MCRIT, because wave drag initially grows slowly after local sonic flow first appears and only becomes significant at a higher Machcorrect
- MDD is always lower than MCRIT because the drag penalty develops before local sonic flow appears anywhere on the wing surface
- MCRIT occurs at M 1.0 while MDD occurs at M 0.5 because these definitions use freestream speed as the sole determining parameter
- They are identical for all aerofoil types because the onset of sonic flow and the onset of significant drag rise always occur at the same freestream Mach
Why A is right
MCRIT is where the flow first goes sonic somewhere on the wing. The shock that forms there is very weak and costs almost nothing in drag. MDD is defined further up, where the drag rise reaches a rate of change of 0.1 per unit Mach, typically 0.06 to 0.10 above MCRIT. The band between the two is the drag creep zone, and transport aircraft cruise inside it deliberately.
The trap
Option D is the tidy answer, and tidy is the warning sign. Sonic flow appearing and drag becoming a problem are two separate events with a real gap between them, and the whole commercial value of a swept wing lives in that gap.

Why students pick SkyStudy
- Padpilot and SkyStudy are complementary as much as alternatives: Padpilot publishes theory books, while SkyStudy gives you 31,032 practice questions to revise against. If what you are missing is question practice, SkyStudy covers it.
- The question bank is free to use during the beta with no card required, with no per-subject purchases.
- Independently authored revision questions, not exam dumps and not the official ECQB.
- Spaced repetition, a free live demo and free weather and flight tools are included in the same place.
When Padpilot is the better buy
Pick Padpilot if you still have the theory to learn. Their product is the reading: interactive books across all 13 subjects, sold per subject or as a complete course, and used by more than 180 partner training organisations. That is the part SkyStudy does not do. A question bank is a revision instrument, and answering questions on a subject you have not read yet teaches you the answers rather than the subject. Most students end up wanting both, and if you have to buy in an order, buy the book first.

What you also get with SkyStudy
Features included with SkyStudy today, beyond the question bank.- Spaced repetition built in. An SM-2 spaced repetition queue brings questions back at the right interval, so revision targets what you are about to forget rather than what you already know.
- Free aviation tools for everyone. Free METAR, TAF, NOTAM and SNOWTAM decoders, plus flight calculators for wind component, density and pressure altitude, ISA deviation, Mach number, true airspeed and unit conversion. No account needed.
- Free pilot aptitude practice. A set of free pilot aptitude practice tests for airline selection, open to anyone without signing up.
- Installable, works offline. Install SkyStudy as an app (PWA) and keep practising offline. Your progress syncs back when you reconnect.
- Community and progress tracking. Community explanations, votes and seen-on-exam reports from other students, plus streaks and progress tracking to keep daily revision consistent.
- Try it before you register. A free live demo lets you work through real questions before you create an account.
