The latest from Peter's Flight Log

I'm training to be a pilot! In these pages I keep a detailed record of my journey and share the ups and downs (literally) with you.
I invite you to join me in my flying adventures!

Training area

Flight 39: Training Area Familiarisation

Flight log Flight 39: Training area familiarisation My first flight after another long break was, in fact, sightseeing. It was a far cry from the usual laps around the airport. In today’s flight, Greg took me around some of the most important landmarks around Camden (from an aviation point of view). I also performed two […]

Circuits, radio issues

Hour 35: Cancelled solo – radio issues

Flight log Hour 35: Solo circuit training I had an internal debate about writing this log, because this flight did not happen. I planned to do a mid-day solo circuit flight (just like for Hour 34), but only managed to taxi to the runup bay before ATC asked me to return to parking due to […]

Circuits, solo

Hour 34: Fifth solo circuits door-to-door

Flight log Hours 34: Solo circuit training door-to-door On Hour 34 of my training, I conducted a full flight as pilot-in-command! We often refer to this flight as “door-to-door”, because the pilot in training completes the entire ground and air components of the flight solo, with the instructor monitoring from a distance. This door-to-door flight […]

advanced, Stalls, training

Hour 32: Advanced stalls

Flight log Hours 32: Advanced stalls Advanced stalls are stall maneuvers and recovery practices that go beyond the basics taught to beginner pilots. These advanced exercises are designed to enhance a pilot’s understanding and handling skills in more complex stalling scenarios that they might encounter in flight. In Hour 32, I practiced these maneuvers at […]

"Power loss", Circuits, emergencies, Flapless

Hour 33: Dual circuits and emergencies

Flight log Hours 33: Dual circuit training on RW06 and RW28 As it was three weeks since my last flight, a circuits solo was not possible. In today’s second flight, I did dual circuits training with Davide. This session was filled with emergencies and my first landing on Runway 28, which is grass, plus my […]

Basic Intrument Flying, BIF, Simulator

Hour 31: Simulator Basic Instrument Flying training

Flight log Hour 31: Simulated for Basic Instrument Flying (BIF) training Today I had hoped to do a door-to-door circuits solo, but the weather, again, did not cooperate. So, Greg suggested I use the simulator to do some Basic Instrument Flying Training. This was a very good alternative to real-world flying, given that BIF is […]





Our courses are designed to be detailed, comprehensive, and descriptive. Learn new skills that specifically apply to your projects.
You are at the right place. We have some of the best content on the Internet right here, ready to dive in.

Arduino Step by Step
Getting Started

The original comprehensive course designed for new Arduino Makers. It will teach you how to use the Arduino and learn about electronics and programming. We designed this course for people just starting now. It's the perfect start for the new Arduino Maker.

Arduino Step by Step
Getting Serious

Tech Explorations Arduino intermediate level

Create Arduino gadgets that can communicate, move, interact, measure and detect. This course picks up where Arduino Step by Step Getting Started left off and shows you how to use dozens of external components and advanced build-in features.

Raspberry Pi Full Stack

Raspberry Pi: Full Stack is a comprehensive project course that will teach you how to build a modern Internet-of-Things application that includes a local web server application written in Python and JavaScript, sensors, buttons and LEDs, and online Cloud services like If This Then That, Google Sheets, Google Charts, and Plotly.

ESP32 For Busy People
