1 in 60 rule trainer
The 1 in 60 Rule Trainer is a free, interactive web app that turns one of aviation's handiest mental-maths shortcuts into hands-on practice. Each round drops you into a fresh scenario — off track between two airfields — and challenges you to work out your track error, correction angle, and the heading correction back to your destination. Enter your answer and the app grades it instantly, then redraws the diagram with the angles and corrected track so you can see how the numbers become a turn. With randomised problems, a whole-numbers mode for beginners and an equation mode for tougher figures, plus a running score, it's a quick way for student pilots to drill their nav maths until it's second nature — ready for the cockpit or a theory exam.
If you need a refresher on the 1 in 60 rule, watch this video.
1. Read the scenario.
You're abeam the lake and off track. Note your total distance, distance flown, and how far off track you are.
2. Work it out.
Use the 1 in 60 rule to find your track error and correction angle, then enter the total heading correction and turn direction.
3. Check your answer.
Hit Check to see if you're on track, with the angles drawn on the diagram and the full solution. Tap New scenario and repeat.
1. Load your checklist
Snap a photo of a checklist or upload a PDF, and it pins to your on-screen kneeboard. Chairfly automatically recognizes the text so it knows exactly where each word sits.
2. Read it on repeat
Press the spacebar (or tap the button on mobile) to start a 5-minute run, then read every line from top to bottom. The goal is simple repetition — keep cycling through the full checklist out loud or in your head.
3. Hide each pass
Each time you press space or tap, a few more words blur out, so you recall a bit more from memory on every pass until the page is blank. If you get stuck, hit Peek (or the P key) to reveal everything for 3 seconds, then keep going until you can fly the whole checklist cold.
Welcome to the ATC readback trainer
Works best in Chrome or Edge — allow microphone access when prompted,
1. Listen
Tap Receive transmission to hear a randomly generated ATC clearance in standard phraseology.
2. Read it back
Hold Push to talk (or the spacebar) and repeat the instruction, just as you would on the radio.
3. Check your score
Release, and the app marks every item correct or missed, then shows exactly what ATC said.
The Magnetic Compass Errors Trainer
The Magnetic Compass Errors Trainer is an interactive drill for student pilots learning how a wet compass misbehaves when you change speed or turn. Work through two modules — acceleration errors and turning errors — across both hemispheres, predict what the compass will do, then watch a realistic compass card react in real time. Each answer comes with a plain-language explanation and the mnemonic that backs it (ANDS/SAND for acceleration, UNOS/ONUS for turning), so the rules actually stick.
1. Pick your topic.
Choose Acceleration errors or Turning errors at the top, and tap the Hemisphere button to drill the Northern hemisphere, the Southern hemisphere, or leave it on Auto for a random mix.
2. Read the scenario
You'll get a heading and a manoeuvre (accelerating, decelerating, or rolling out of a turn). Choose what the compass will indicate from the options below.
3. Watch and learn.
The compass animates the error so you can see it happen, and you get instant feedback with the reasoning and mnemonic. Hit Next scenario to keep training and build your streak.
Reciprocal heading trainer app
Reciprocal Trainer turns one of aviation's quickest mental skills into instant recall. A heading appears, the clock starts, and you tap in the reverse course — exactly 180° opposite — racing your own time. Every answer is scored on speed and accuracy, so the numbers you'll need in the circuit or under the hood become second nature. Free, runs in any phone browser, nothing to install.

Know all the V-speeds
Think you know your V-speeds? The V-Speed Checkride is a quick, interactive quiz built to go with our episode "All the V SPEEDS you need to know." It throws you twelve real-world scenarios — engine failure on takeoff, an obstacle off the runway, turbulence ahead — and asks you to call the right speed from three options. Every answer comes with a plain-English explanation, and your score drives a working airspeed indicator that climbs into the green as you get them right. Miss a few? The end-of-test report links you straight back to the exact moment in the video to brush up. Perfect for student pilots prepping for exams or anyone keeping their numbers sharp.
Step 1
Read the scenario and pick the V-speed you think fits from the three options.
Step 2
Get instant feedback on every call, with the reasoning and a link to that point in the video.
Step 3
Check your debrief at the end. Tap any speed to jump back to the video and revise the ones you missed.
CTAF procedures trainer
Nail your radio calls before you key the mic. This free, interactive trainer walks you through the standard arrival and departure broadcasts at non-towered (CTAF) aerodromes. The calls every student pilot is expected to know. It spins up a fresh scenario every time — different runway, wind, circuit direction and join or departure type — so you learn the procedure, not a script. Follow each leg on a live circuit diagram with every call broken down by element, then switch to quiz mode and get an instant debrief on how your CTAF knowledge is tracking. No sign-up, nothing to install — it runs right in your browser.
1. Choose your phase.
Tap Inbound or Outbound, then New scenario for a fresh aerodrome, runway, wind and circuit to practise.
2. Walk it through.
Step through each leg on the diagram and read the recommended call, colour-coded by element — location, callsign, position, intention and runway.
3. Test yourself.
Switch to Quiz, pick the correct call at each point, and review your end-of-quiz debrief to see exactly what to brush up on.
