John Bell Tools

This is a bit of a hodge podge of things I put together. It is also a little experimental while I learn how to cache pages. While this is meant to be functional, its biggest purpose is to demonstrate how some useful tools could be developed and used on the iPad using html with JavaScript. Once you navigate to this page, it will be available offline. You can even make a home screen icon to easily access it.
The pages themselves are html and JavaScript. This page which provides the links uses the html 5 appcache feature to save the linked files.

Tools

Reserve Pay Calculator

This allows you to calculate the value of a reserve line to help you decide whether to bid for a regular or reserve line.

Jepp FD Alternates

This is a list of the alternates that allows you to enter a position and get the closest alternates for pasting into Jepp FD. You can also jump to links to see the airport in Google Maps. You must be online for the links to work. My html flight plan (HTML Flight Plan) has a better tool embedded that finds the alternates along the route instead of at a point.

Rest Break Calculator

This is a stripped down version of the rest break calculator generated in my html flight plan (HTML Flight Plan). However, it works when the html version of the flight plan is not available.

Conversions and Crosswind

This is just a very simple converter and crosswind calcualtor. There are far more robust apps in the app store, but this should be enough for METAR and crosswinds.

ETP Extract Tool for Jepp FD iOS

This is a tool that extracts the ETP information from the flight plan to facilitate creating ETP points using the user point feature in Jepp FD for iOS.

777 operational landing distances

This used ODM data, but is NOT FAA OR DELTA APPROVED! Thus, I highly advise caution. However, it is very useful to see how a "smart document" could be used in a document library as well as how it works in this context.

M88/90 operational landing distances

This used ODM data, but is NOT FAA OR DELTA APPROVED! Thus, I highly advise caution. However, it is very useful to see how a "smart document" could be used in a document library as well as how it works in this context.

737 operational landing distances

777 Flash Cards

These are some flash cards that I wrote for the 777. At this time, it is jsut a review of limitations and memory items. I use Excel to create the html file. You are welcome to the Excel File to create your own. I have those files linked from the main page of johnfbell.com

Usage tips

Add to home screen

You can bookmark this page. However, I suggest you add an icon to your home screen. Note that this also works well with the PBS Web App https://dalpbs.navblue.aero/webapp.
