Aleks and Colin, the founders of Boldmethod

We're Aleks and Colin, the founders of Boldmethod. We've flown our airplane through mountain weather from the Appalachians to the coastal ranges of California, and we built this course around what we learned along the way.

Want to feel more comfortable in the high country?

Terrain creates updrafts, downdrafts, turbulence, and storms, and it changes the wind throughout the day. You'll learn how these conditions form, where to find them in your reports and forecasts, and how to spot them in flight. It applies in every season, in any mountain range or hilly terrain.

Everything you need to plan around mountain weather.

Mountain waves, explained.

Learn how waves and rotors form, how to spot them in forecasts and in flight, and what to do if you get caught in one.

Winds that change all day.

Valley and slope winds shift from morning to evening. Learn how to time your departure and arrival around them.

Real flights in real conditions.

Every flight is filmed in our airplane, from the Appalachians to the California coast. No simulators, no stock footage.

Airflow and the Mountains Airflow Over the Mountains Airflow Around or Through the Mountains Diurnal Winds Mountain Thunderstorms Meteorology Basics

Airflow and the Mountains. How terrain shapes airflow, and why mountain weather behaves so differently from flat land weather.

Over 14 hours of video, with a quiz after every lesson and a test at the end of each chapter.

Real weather. Real decisions.

Each case study uses actual reports, forecasts, and footage, so you see how these conditions play out in real flying.

Flying in mountain waves

Wind River Range, WY and Sangre de Cristos, COWhat wave activity looks like from the cockpit, how to use PIREPs and forecasts to plan around it, and what to do if you run into it.

Do I need to fly in the mountains to get value from this course?

No. These weather systems show up in hilly terrain across the country, not just the Rockies. If you fly anywhere with real terrain, the concepts apply.

How long is the course?

Over 14 hours of video. Lessons include summaries and quizzes, and each chapter ends with a test. Work through it at your own pace.

Are there quizzes and tests?

Yes. Each lesson ends with a quiz, and each chapter ends with a test. You can retake them as many times as you want.

What if it doesn't work for me?
