01 Introduction to Flying and the Path to a Certificate What a Private Pilot certificate lets you do, the training path from ground school to checkride, medical certificate basics, Part 61 versus Part 141, and honest numbers on the hours and cost it takes to earn your wings. 14 min read · sign up to open LockedUnit 1 02 Aircraft Structure, Systems, and Powerplant The training airplane from the outside in: airframe and flight controls, the four-stroke engine, magnetos, carburetor versus fuel injection, carburetor ice, the propeller, and the oil, electrical, and fuel systems that keep it all running. 18 min read · sign up to open LockedUnit 2 03 Principles of Flight and Aerodynamics The working aerodynamics a pilot actually needs: the four forces, how a wing makes lift, angle of attack and the stall, parasite and induced drag, stability, load factor in turns, and ground effect. 17 min read · sign up to open LockedUnit 3 04 Flight Instruments and How to Read Them Where each flight instrument gets its information: the pitot-static altimeter, airspeed, and VSI, the gyroscopic attitude, heading, and turn instruments, magnetic compass errors, glass cockpit basics, and how to recognize a failure. 18 min read · sign up to open LockedUnit 4 05 Weight, Balance, and Aircraft Performance Why weight and balance matters, the vocabulary of CG and moment, a worked balance calculation, reading performance charts, and how density altitude robs performance, using Centennial Airport's 5,883-foot field elevation as the example. 17 min read · sign up to open LockedUnit 5 06 Airports, Airspace, and the National Airspace System Airport markings, signs, and lighting; flying a standard traffic pattern; and Class A through G airspace by real dimensions and entry rules, seen through Centennial's Class D and the Denver Class B shelves. 20 min read · sign up to open LockedUnit 6 07 Radio Communications and ATC Procedures The phonetic alphabet, building a radio call in the right order, who you talk to on ground, tower, approach, and CTAF, plus lost-comms light gun signals and transponder codes, with real KAPA frequencies. 16 min read · sign up to open LockedUnit 7 08 Aviation Weather Theory and Hazards The atmosphere, pressure and wind, air masses and fronts, moisture and stability, and the hazards that matter most on the Front Range: thunderstorms, icing, fog, mountain wave, wind shear, and density altitude. 23 min read · sign up to open LockedUnit 8 09 Weather Reports, Forecasts, and Charts Decode a METAR and a TAF field by field with fully worked Centennial examples, plus PIREPs, winds aloft, AIRMETs and SIGMETs, the charts you will use, and how to get a legal weather briefing. 20 min read · sign up to open LockedUnit 9 10 Federal Aviation Regulations and the AIM How Title 14 is organized, the Part 61 rules on certificates, currency, and the flight review, and the Part 91 rules on right-of-way, VFR weather minimums, preflight action, and required equipment. 22 min read · sign up to open LockedUnit 10 11 Aeromedical Factors and Aeronautical Decision Making Your body was not built for altitude. Learn how hypoxia, carbon monoxide, dehydration, and sensory illusions degrade a pilot, and how IMSAFE, the hazardous-attitude antidotes, PAVE, and the DECIDE model keep your judgment sound. 16 min read · sign up to open LockedUnit 11 12 Navigation, Charts, and Cross-Country Planning Read a VFR sectional, convert a true course into a compass heading, solve the wind triangle for heading and groundspeed, and plan a full VFR cross-country from Centennial Airport south to Colorado Springs. 22 min read · sign up to open LockedUnit 12 13 Night Flying and High-Density-Altitude Operations Why your eyes struggle in the dark, what night currency and the three definitions of night require, and how thin Colorado air stretches every takeoff roll and climb at a mile-high field like Centennial. 20 min read · sign up to open LockedUnit 13 14 The Written Exam and Checkride: What to Expect A walk through the FAA knowledge test and the practical checkride: getting endorsed, the ACS, the oral and flight, what examiners watch for, common failure areas, what to bring, and your next step at Centennial. 16 min read · sign up to open LockedUnit 14
Questions

Before You Start

Is the ground school really free?
Yes. Create a free account and every lesson unlocks. We ask who you are so we can point you to the right flight school at Centennial Airport when you are ready to fly — that is how the site stays free.
Does finishing this get me a certificate?
No. This is knowledge training. A Private Pilot certificate requires flight training with a certificated instructor and passing the FAA written exam and a practical test. This ground school prepares you for the knowledge side and helps you start flight training with a head start.
Do I need to sign up to read the lessons?
Yes. The lesson content is behind a free account. Signing up takes about a minute and lets you track which units you have finished.
Who wrote this material?
It follows the current FAA Airman Certification Standards for the Private Pilot certificate, written in plain language. Always confirm regulatory specifics against current FAA sources before a checkride.
