All Engine Failure Training Tool

This is an installable web application for exploration of energy management and navigational strategy following failure of all engines on an Airbus A320. It should work with any modern web browser.

A background information document is available. This discusses the inferences used in the creation of the flight model and my personal strategies.

A320 Flashcards

My personal, not official in any way, A320 flashcards, in the form of an installable, “offline first” web application. Use it entirely at your own risk!

It was created to help me memorise the essence of complex procedures, allowing ECAM procedures, QRH checklists etc. to be used as tools for finesse rather than as unfamiliar or long forgotten recipes. The flashcards are highly opinionated; where alternative actions exist, such as the use of TOGA early in an asymmetric takeoff, my preference is what you will see.

The application implements the Leitner Proficiency Levels algorithm, as described by Wikipedia . This optimises memorisation by presenting flashcards that you tend to get wrong more often than those that you tend to get right.

Any reasonably modern web browser should work fine. After visiting the web page for the first time, the application will be available offline. It will automatically update whenever the page is visited with an Internet connection available.

The application can also be “installed”, which really only means that an icon is placed on your home screen or desktop, and the browser controls are hidden to make it look more like a native application. The exact method depends on the combination of your browser and operating system, so if your browser doesn't make it obvious, you will need to google it.

Note that Apple devices are somewhat hostile to web applications (they don’t generate any revenue for Apple), and will delete both the offline cache (destroying offline capability) and browser local storage (destroying your saved progress) after a week unless you “signal your intentions” by installing. They then give almost no indication how to install — while visiting the page in Safari, you need to click the “share button” (a box with an upward arrow, for some reason) and scroll down to find “Add to Home Screen”.

electronic Flight Journal

This is a set of tools and documentation supporting the recording of personal flight data in a simple text file. The tools are made available both as a web application and as a locally installable, cross platform Python application.

Capabilities include export of FCL.050 compliant logbooks, summarisation of flying and accurate calculation of regulatory night flying.

AIMS Data Extraction

This is a tool to extract data from either a downloaded “Vertical” AIMS roster or from an AIMS Logbook Report. Output formats are eFJ (see above), iCalendar (Google Calendar, Outlook etc.) or CSV (Excel et al.). It is available as a web application and as a locally installable, cross-platform Python application.

The version of AIMS targeted is the July 2024 update at easyJet. If you are not an easyJet pilot, it may work for you if your airline is using the same version.

Bristol Arrivals Conflict Analyser

This web application applies a statistical analysis to the Bristol Airport Arrivals board to provide the probabilities of various quantities of other aircraft arriving 10 minutes or less before you.

Discretion Calculator

An installable web application providing an extremely streamlined calculator to determine latest UTC on blocks time for easyJet pilots and cabin crew operating under the UK AOC FTL scheme. Just enter five digits, where the first four digits are your UTC report time and the fifth digit is the number of sectors.

Note that George Botley’s excellent “Orange Toolkit” will give you the same information using a more traditional interface, which you may prefer.

SSG Static Website Generator

A static website generator leveraging Jinja templates, TOML and Python.

This was originally written to prototype a “raw” mode for Zola, but diverged too far from Zola’s fundamentals to work in that context. It turned out, however, that it worked really well as a standalone application, at least for me. As always, your mileage may vary.
