Knotes
PPL ground school · SACAA syllabus

PPL study notes you can check.

Knotes takes you through the seven PPL theory subjects one topic at a time, with notes you can check and a study assistant that only answers from those same notes. When they don't cover something, it says so instead of guessing. The notes are written by a fellow student pilot and published subject by subject, so check them with your instructor as you go.

  • Built on the 7 PPL subjects
  • Answers show their sources
  • Light on mobile data
StudentWhy is my take-off roll longer at FAJS on a hot afternoon?
From the course notes2 sources

Heat and elevation both lower air density. Johannesburg sits at 5,558 ft, so on a 28 °C afternoon the density altitude can exceed 8,000 ft(source 1). Thinner air means less engine power and less lift, so you need more runway(source 2).

How it works

Read it, then question it.

Each topic follows the same steps, so you always know what comes next. Short videos will join them later.

  1. Step 1

    Read the topic notes

    Notes follow the SACAA PPL syllabus in order, from Air Law through to Principles of Flight. Each topic ends with a short list of key facts to revise from.

  2. Step 2

    Ask the study assistant

    Ask anything about the notes. The answer lists the exact sections it used, so you can read them yourself before your exam.

  3. Step 3Coming soon

    Watch the short video

    Where a diagram explains it better, a video of under five minutes is planned. None are ready yet, so for now, read the notes instead.

The study assistant

It would rather say “not in the notes” than guess.

In a multiple-choice exam, the wrong options are often the ones that sound right: close to the exact regulation you half-remember, but not quite it. A general chatbot doesn't know that: it gives you a fluent, sure-sounding answer whether or not it's actually correct. The Knotes assistant only answers from your course notes, shows the exact passage behind every answer, and tells you plainly when the notes don't cover something, instead of filling the gap with a guess.

Sources
Every answer lists the note sections it drew from, so you can read the passage yourself.
Limits
If the notes don't contain enough to answer, you get a clear “not covered” reply instead of a guess.
Scope
It won't answer from the open internet, and it won't give live operational information like NOTAMs, weather or fees.
Your call
It is a study aid. Your instructor and the current regulations remain the authority.
