Further XPDisplay improvements

XPDisplay now has a ‘Data’ tab, which (currently) displays charts with approach glideslope and landing gear forces, for post-landing analysis:

Glideslope

Glideslope - showing a late approach and landing!

Landing Gear Forces

Landing Gear Forces

Charts are updated in real time and can be zoomed, printed or exported as PNG images (thanks to the excellent JFreeChart library).

Caveat: these features are not in the current released version of XPDisplay yet.

XPDisplay improvements in the pipeline

After a couple of months with hardly any time to work on my personal projects, it feels great to be developing again! This is a screenshot of XPDisplay, showing the new airport information display on the map tab:

The airport information is read from the same apt.dat file that XPlane uses, so everything is kept nice and consistent.

Panshanger scenery for X-Plane

This is my first attempt at a scenery package for the X-Plane flight simulator, using only Sketchup, GIMP and WED (plus the library objects that come with X-Plane and OpenSceneryX). It covers my local airfield (Panshanger Aerodrome), which is home to the excellent North London Flying School.


The scenery covers most of the main objects on the airfield, although there is always room for improvement (in particular the main hangar needs remodelling from scratch). Bengeo water tower is included, as it is a prominent local feature that pilots sometimes use for navigation.

To download the scenery, or for more information, please click here.

I’ve shared the code on GitHub under a public domain license – improvements welcome.

Edit: I’ve also uploaded this to the official X-Plane.org website.

More Aircraft Traces

Here are two more traces, generated from a whole day’s worth of data (29th June 2013). I’ve added some more ground locations as well as the places which the ‘stacks’ are named after (BOVINGDON, LAMBOURNE, BIGGIN and OCKHAM). Happily they coincide nicely with the loops which indicate where aircraft are circling. Colours here are assigned randomly to different aircraft.

The second trace is coloured according to altitude (purple corresponds roughly to 35,000ft – 40,000ft, down through green, yellow, orange and finally red, which corresponds to 5,000ft – 2,000ft).

You can clearly see high altitude routes (purple) as well as the stacks and approach routes into Heathrow. I expect that the routes into and out of Gatwick would also be visible if the range of my receiver was better. I’ve tried building a custom aerial, but haven’t had any luck with it so far.

For completeness, here is a trace coloured according to speed. Purple indicates 500-600kts, down through green, yellow and red at about 100-150kts.
