About
From AutoPilot: offline flight training drills made by a CFII.
Drag the airplane. Watch the rule change.
Airspace Trainer turns 14 CFR 91.155 from a table you memorize into a picture you understand. Move the airplane through Class B, C, D, E and G, above and below 10,000 feet, and watch the required visibility and cloud clearance update as you go. Drag it anywhere, or use the Left, Right, Climb and Descend buttons to move it one line at a time.
BUILT AROUND ONE QUESTION
Is this flight legal? Every scenario drops you at a specific place and altitude and asks you to call it. When the answer is no, it asks the harder one: which rule decides it? Knowing the answer is not the same as knowing why.
EVERY VERDICT CITES THE REGULATION
No hand-waving. Each answer comes back with the section number behind it, so you can trace it to the source and say it out loud on a checkride oral.
THREE ALTITUDE BANDS, NOT THIRTEEN ROWS
The 91.155 table is famously miserable to memorize. Airspace Trainer teaches the structure underneath it: what changes at 10,000 feet, what changes at 1,200 AGL, and which classes actually behave the same way.
FIND OUT WHERE YOU ARE WEAK
Progress tracking shows which airspace classes and which rules you keep missing, so study time goes where it counts instead of where it is comfortable.
THE WHOLE TABLE, FOR LOOKING UP
A clean 91.155 reference is always one tap away, for when you need the number rather than the drill.
WHO IT IS FOR
- Student pilots working toward a private or sport certificate
- Anyone prepping the FAA knowledge test or a checkride oral
- Rated pilots knocking the rust off before a flight review
- Instructors who want a whiteboard that answers back
No account. No ads. No data collected.
Airspace Trainer is a study aid, not a substitute for the current regulations or your instructor's judgment. Always fly by the FAR/AIM and your operating limitations.
