Founder - Keynomen

Hi. I'm Daniel.

Keynomen is pronounced “Key-Nomen”.

Words are Key to unlocking the understanding of a subject. From Latin Nomen (name) and Calare (to call out), comes the word Nomenclature which is a fancy word for jargon - the technical words of a subject.

Keynomen is here to provide you those Key Names (or key words) that unlock your understanding. Master the words to master the subject. That certainty is what carries you through the training - and it stays with you long after the checkride.

To benefit from these tools - you have
to know what the words mean.

Test Prep - a painted panel of a test booklet, a flight computer and two pencils on a desk, with five aviation terms printed under it in a band of yellow highlighter: Moment, Isogonic, Hypoxia, Datum, Aneroid.

Instruction - an instructor and a student seen from behind in a cockpit, the instructor pointing at the panel, with five aviation terms printed under it in a band of yellow highlighter: Detent, Aileron, Chandelle, Carburetor, Porpoising.

Here's where Keynomen fits in.

Keynomen sits underneath everything else you're using - ground school, online school, private instruction, flash cards, test prep. You learn the language of aviation in an easy, relaxed way. Simply work your way through your list - marking each term “Log as Cleared” as you go along.

Know where you stand - track your skills

Version 1 of Keynomen was live when I read Jamie Beckett's article: The Most Important Documents in Aviation in General Aviation News. A CFI since 1991, he argues that no one should begin flight training without a syllabus - that for owners, instructors and students alike, the syllabus can and should be your best friend.

He's right. That article inspired me to build this version.

Now you can keep track of your progress. It's your confidence in your skills that drives you through the training, so here's a tool that shows you where you stand - your strong areas, and the ones that need more attention.

Is Keynomen an AI tool?

No. There is no live AI call when you use Keynomen. Nothing is written on the fly. Every definition follows a structure I developed, built from a deep understanding of where study breaks down.

Look up empennage here. Then look it up in ChatGPT. Try a few more terms. You'll see the difference.

Did I use AI tools in building the product?

Yes. It started with the FAA publications. About 25,000 terms extracted. Just the words, not the definitions. I developed a specific methodology for providing the meanings.

AI tools can drift. Give one a list of 10 terms to define and the first few may be good, with the last few deteriorating. To prevent that from happening, every single word was given to the LLM, one at a time. The LLM would read my full set of instructions and perform the task once, then read my full set of instructions again — and perform the next task. Over and over, 25,000 times. I did this with four LLMs, so roughly 100,000 passes of the same human instructions. Then I combined the best result from each LLM into what you see today. Finally I used AI tools to build the app that delivers the content.
