I’ve been virtually flying on VATSIM for some time now, and the small Diamond DA40 is great fun, especially for Visual Flight Rules (VFR) operation. With its Garmin G1000 flight management system, flying Instrument Flight Rules (IFR) to and from larger airports is also a lot of fun, especially since the software was updated to the “NXi” version in the simulator last year, which supports pretty much the whole range of IFR procedures. It’s also fun to be the ‘odd-duck’ in the traffic flow, as the DA40 is obviously much slower than airliners, which has air traffic controllers sweating a bit to squeeze me into an approach queue on a Friday evening. The downside: Due to the relatively low speed of the DA40, the number of airports to fly to and from in VATSIM is limited by the time it requires to fly between them. So the obvious ‘next step’ was get into a somewhat faster plane.

Starting at some point in December last year, I suddenly started to get Chrome crashes on a Windows 10 installation running in Virtualbox virtual machine. Over time, the crashes got more frequent and annoying, so I started an investigation. What I found out totally took my by surprise.

Recently, I decided to buy an emergency radio receiver that would double as a radio for the kitchen. On of the main “must have” features for me is of course to be battery driven, so it will still work should power fail. There is a wide choice of radios for this purpose but the more I looked, the more I noticed that I would like to have a number of features beyond just a battery driven radio.

So here we go, it’s 2023 and this blog has once more moved to another host. Initially started as a blog on Typepad in 2005, it has so far moved to a hosted server platform on which I installed WordPress (2016), to a virtual machine I could administer on my own (2018), and then, two years ago, into Docker containers on a VM (2021). Now it was time to move on again!

In episode 3, I’ve looked a bit on how flight planning and navigation software for ‘the real world’ can be used in a flight simulator. Using such software is a huge step beyond the built-in navigation tools when it comes to flying in the simulator as realistically as possible. Next in my list of things to improve was radio communication with Air Traffic Control (ATC). MS Flight Simulator 2020 has built in Air Traffic Control, and interaction with it is done by selecting pre-formulated requests and answers from a drop down menu. That’s not very realistic and lightyears away from the challenge of talking to real people at the other end of a radio channel. But there’s a fix for that: VATSIM.

Another crazy year, both good and bad in so many ways, is coming to an end, so here I go with time honored tradition of looking back to what moved me this year in tech!

In The Wireless Domain

Obviously, there’s been a lot going on in the wireless domain again. While some parts of the 3GPP 5G standard still struggles a bit to see the light of day, there have been very interesting advances in the real world despite of it:

LTE 5-carrier aggregation is now out there in the wild now, and network operators have started to use somewhat less mainstream spectrum and aggregate it. An interesting example was the TDD-TDD carrier aggregation of LTE band 40+40 I noticed in the UK.

Also, cellular coverage along railway lines in Germany has improved quite a bit in recent years, and I’ve written about my experience on a trip from Cologne to Hamburg here.

I’ve known for a long time that LTE has re-introduced a timing advance again, but it was only this year that I actually found out how to get to this value in the tracing tools I use. It’s perhaps a small thing, but it definitely helps to get a general idea how far a cell site is away.

This year, I’ve also been traveling a lot again, and I was delighted that I could use 5G NSA networks in most countries I traveled to. In some countries like Sweden, the Netherlands and Austria, networks were stunning, while in countries like Italy, networks have lost a lot of their luster in recent years.

And while I’m talking about roaming: I’m delighted that some device manufacturers have now also noticed that their network discovery algorithms in manual network selection mode took far to long and changed them to list networks immediately after they are found. This way, one can get online again significantly faster after crossing a border.

One more thing on roaming: While having become a pretty seamless affair in the EU these days, eSIMs for roaming elsewhere have become an interesting option. After having written about the technology many years ago, the technology has finally arrived in the main stream. So while traveling, I used the opportunity to play around a bit with downloading eSIMs for roaming and was surprised on the one hand how easy it has become, and on the other hand just how many different companies are involved in the process.

In part 2 of this series, I’ve been looking at resources available from books to videos on Youtube to learn flying in the virtual domain. For me, a mix of real world examples and examples shown with a simulator made most sense. So for a couple of months I was flying happily on the simulator on the X-Box and picked up some interesting apps along the way that people use for flight preparation and during flight in the real world. As my goal is to fly as realistically in the simulator as possible, I had to change tactics a bit to also use those tools in the virtual world.

There are many different ideas and reasons to pick up flight simulation as a hobby and I’ve laid out mine in the first part of this series. While most people seem to be interested to fly airliners and start right in an Airbus A320 cockpit, I was much more interested to make the experience as ‘real’ as possible. The appeal of flight simulation to me was to get as close as possible to flying small planes, so I started in a small Cessna with a classic ‘six-pack’ instrument panel. After a week or two, I moved to a Cessna 172 with a a Garmin G1000 ‘glass cockpit’, i.e. electronic instruments. Again a few weeks later, I ‘upgraded’ to a Diamond DA 40 NG 4 seater, also with a Garmin G1000 instrument panel and full autopilot. The flight lessons provided in MSFS2020 are very good for the basics, but to fly as realistically as possible, there’s a lot more to learn. Fortunately, there are many resources, both for real and virtual flying out there and in this episode, I’ll have a look at the classic approach: Getting some books on the topic.

I’ve had a fascination for flying pretty much for as long as I can remember and some years ago, I bought my first book that taught me the theoretical knowledge required for a private pilot license. But for a number reasons, flying a small airplane in reality hasn’t been in the cards so far. Also, I was not very interested in exploring the possibilities of a flight simulator, so the dream remained a reading exercise. However, several things have changed my mind about flight simulators recently.

Some trends in the tech industry can be rather slow. Take wireless mice, for example. I’m pretty sure that for more than a decade, wireless mice with a Bluetooth air interface have been on the market. I bought one 3 years ago but couldn’t use it because Ubuntu 16.04 would not support it. I tried again using it after upgrading the OS, but I didn’t like the hard to press buttons and the loud clicking sound of the model I bought. The Bluetooth link itself was working nicely, though. Recently, however, I had to come back to the topic when a USB port on my Lenovo X13 stopped working and I couldn’t connect a USB mouse dongle anymore.
