Graphical User Interface

This is a simple, cross platform, Tk based Graphical Interface.

The menu bar provides “File”, “Edit”, “Modify”, “Export” and “Help” sub-menus. The “File”, and “Help” sub-menus should hopefully be self-explanatory.

The “Edit” sub-menu should also be mostly self-explanatory. “Recenter” scrolls so that the cursor is vertically centred in the window, unless that is already true in which case it scrolls so that there are two lines of context above the cursor. “Complete Line” finds all other lines in the text that start with the same characters as the current line, and adds characters to match the common characters at the start of those lines — it’s particularly useful for completing the type of an aircraft you have flown before given the registration.

For the “Modify” and “Export” sub-menus:

Modify

The tools in the “Modify” submenu modify the eFJ in place. If some text is selected in the text editor (e.g. with a mouse), only lines with selected text are modified.

Expand

The eFJ scheme aims to make it as easy as possible to manually enter flight data where no better alternative is available. To support this, a couple of short forms are allowed that infer data from previous data. This tool expands out these short forms, which makes them more human legible.

Night

Updates eFJ with calculated night duration and, where necessary, night landing.

G-ABCD:A320
BRS/BFS 1600/1700
BFS/BRS 1800/1900

becomes:

2024-01-01
G-ABCD:A320
BRS/BFS 1600/1700 n:20 ln
BFS/BRS 1800/1900 n

If night duration is already recorded for any sector, that sector is not updated.

VFR

Adds a flag to every sector to indicate that it was flown under visual flight rules.

BRS/BFS 1600/1700 v
BFS/BRS 1800/1900 v

FO

When no role flag is included, it is assumed that the role was p1. This means that First Officers must mark each sector as p1s, p2 or put. Captains, on the other hand, just have to mark sectors where they were PM for the landing with m. This tool allows First Officers to also just use m and then auto-fill the roles as p1s or p2 by assuming their role was p1s if they landed the aircraft and p2 if they did not.

BRS/BFS 1600/1700 p2 m
BFS/BRS 1800/1900 p1s

Instructor

Adds the ins flag to any sector that does not already have it.

G-ABCD:A320
BRS/BFS 1600/1700
BFS/BRS 1800/1900

BRS/BFS 1600/1700 ins
BFS/BRS 1800/1900 ins

Export

The tools on this menu produce standalone HTML files. These files have no dependencies, so can be copied and moved around at will. They can be opened in any reasonably modern web browser, spreadsheet or word processing program.

FCL.050 Logbook

The EASA FCL.050 Acceptable Means of Compliance, which has also been adopted by the UK CAA, details the format required for personal flight records. The FCL.050 Logbook tool converts an eFJ into a compliant, standalone, HTML file.

Summary

The Summary tool provides various statistics for the eFJ as a standalone HTML file.

The results include a breakdown of flying roles, aircraft classes, conditions and landings by aircraft type, and all relevant totals.

Cumulative Totals

The cumulative totals tool provides the cumulative totals for every sector as a standalone HTML file.

When a date range is specified, this only restricts the dates included in the output; the calculation still includes all entries.

Restrict Dates

This menu item brings up a toolbar with “First” and “Last” fields. Each of these fields may be left blank (implying no restriction), or a date with the format 2026-09-30 or 20260930 may be entered. If such a date is entered, the tools in the export menu will only include records between and including those dates. The date range that will be applied to exports is shown on the status bar.

For the Summary, only records with applicable dates are included in the calculation. For cummulative totals, all records are included in the calculation, but only the applicable dates are included in the output.
