Radiosonde Data for Pilots: The Preflight Tool You're Probably Ignoring
Learn how to use radiosonde data and Skew-T diagrams in your preflight briefing. Free, updated twice daily, and richer than METARs or PIREPs for understanding weather aloft.
Professional multi-engine flight instruction in the San Francisco Bay Area. From your initial multi-engine rating to complex aircraft transitions, I'll help you build the skills and confidence to command twin-engine aircraft safely.
I provide multi-engine flight training in the Bay Area as a certified multi-engine flight instructor and professional ferry pilot. I specialize in scenario-based training that helps pilots become confident, competent, and safety-minded aviators, with an emphasis on real-world decision making, risk management, and practical skills you'll use every time you fly.
I'm based at San Martin (E16) and teach most of my multi-engine lessons in the Duchess out of Reid-Hillview (RHV), meeting pilots across the South Bay and Peninsula — San Jose, Morgan Hill, Palo Alto, and beyond. Most students come for a multi-engine add-on, checkride prep, or a transition into a Beechcraft twin, and we build each lesson around the way you actually learn.
