Look Inside the Book

Every page has a big drawing and a box with the numbers, rules and steps you need to know:

The Problem Isn't You. It's How It Was Explained to You.

It's 10 p.m., the app asks about the constant-speed prop: oil pressure drops, so what does the prop do? You've seen this answer before, and it's gone.

The handbook describes the governor in paragraphs: flyweights, speeder spring, pilot valve, oil, counterweights. Five moving parts, explained with words only. By the third paragraph you've lost which way the oil pushes.

Prop governor cutaway: oil pressure loss on most singles means low pitch, high RPM

In the book, the governor is cut open on one page. Flyweights, spring and pilot valve drawn in place, with the oil path in color. Next to it, one line in a box: on most singles, no oil pressure means low pitch, high RPM.

The rest of the complex airplane works the same way: the turbo and its wastegate, the retractable gear, the flaps, manifold pressure, the throttle-prop-mixture order. Each one has its own page.

So when the question comes back worded differently, or the DPE asks it out loud, you picture the governor and explain it without opening the handbook again.

Same Topic, Two Ways to Study It

THIS
  • The handbook: line after line
  • The V-g diagram explained in words only
  • You walk into the test still unsure
The V-g diagram, or flight envelope, presents the relationship between indicated airspeed and load factor for a given aircraft. The curved lines originating at zero represent maximum lift capability, beyond which the wing stalls. The horizontal boundaries correspond to the positive and negative limit load factors, which for normal category airplanes are 3.8 and -1.52 G. The intersection of the positive stall line with the limit load factor defines maneuvering speed. The normal operating range extends to Vno, beyond which flight is restricted to smooth air, terminating at Vne.
FOR THIS
  • The V-g diagram in one drawing
  • Va, Vno and Vne in a box
  • You see it and it clicks
Va 112 kt at 3,100 lb becomes about 99 kt at 2,400 lb

One Page, One Topic, All Clear

Think of it this way:

The DPE puts a loading problem in front of you: 3,000 lb airplane, the CG has to move one inch forward, and you can move bags 60 inches, from the aft baggage area to the front seat. How much weight do you shift? He waits for the number and the why.

In the book you open the weight-shift page and the formula is drawn on the airplane, with that exact example solved step by step: 50 lb shifted, every number in its place.

TC 090°, wind 360/20, TAS 100: TH 078°, MH 068°, CH 070°, groundspeed about 98 kt.

Same with density altitude, the takeoff distance chart, the VFR minimums table, the chandelle and the four elements of common carriage: each one on its own page.

Commercial Pilot Illustrated is 69 illustrated pages in 9 parts, one topic per page, and it ends with the frequent errors on performance, W&B and regs, plus a test-day checklist.

What you see drawn, you don't have to memorize.

Frequently Asked Questions

Is it for me if I got my Private years ago and I'm coming back to go for the Commercial?

Yes. It starts from what changes between Private and Commercial and goes straight to the Commercial topics: the V-g diagram, complex systems, performance, W&B, weather, Parts 61, 91, 119 and 135, and the maneuvers.

Where does the content come from?

It's checked against the current FAA Commercial Pilot for Airplane Category ACS (FAA-S-ACS-7B), 14 CFR Parts 61, 91, 119 and 135 as currently published in the eCFR, the Pilot's Handbook of Aeronautical Knowledge (FAA-H-8083-25) and the Airplane Flying Handbook (FAA-H-8083-3).

Is this official FAA material?

No. It's an independent illustrated study book. It's not published, approved or endorsed by the FAA.

Does it replace my CFI or ground school?

No. It's study material that sits next to your training. It doesn't give you the endorsement you need to take the knowledge test or the checkride: that still comes from your CFI or your ground school. It doesn't replace your instructor, the POH/AFM or current charts, and it's not for real-world navigation: charts and W&B examples are for study only.

Are the practice questions the ones on the real test?

No. They're exam-style questions written for this book, with explained answers. The FAA's test bank isn't public.

When and how do I get it?

The book and the 2 bonus books come as a PDF by email, to the address you enter at checkout. It's a one-time payment, no subscription.

I already have a question-bank app and a video course. Why a book?

Keep them. The app tells you if an answer is right; the book shows you why, on one page you can find again. When the question comes worded differently, or the DPE asks it out loud, you picture the governor, the V-g diagram or the weight-shift drawing instead of hunting for a memorized answer. And unlike a video, you can flip to the page in ten seconds the night before the oral.

Can I have it on paper?

It's a PDF, not a shipped book. Read it on your iPad or tablet, or print it at home or at a print shop and keep the pages you need in your flight bag or at the FBO.

How does the refund work?

You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.

Before You Close This Page

No more rereading without anything sticking.

The V-g diagram: you see it drawn and you've got it.

You walk into the test and the oral knowing where everything is.
