What if we could all share flight data?
Presenting The

Our Mission for Aviation Safety
Flight Data Services believe we could all have safer air travel if the aviation industry had a common platform to share flight data. That's why we share our software. Flight Data Services have a policy to place key elements of their flight data analysis processes into the public domain in an effort to promote flight safety through establishment of a lingua franca. This is seen as a way to cut through arguments like “my data is incompatible with yours” and pave the way to greater cooperation, collaboration and sharing of safety information. We make aviation safety our number one priority.

From Using Quaternions for Visualisation
on June 6, 2017

  To my regular readers, I apologize for the absence of a blog in recent weeks. A severe tummy bug during a conference in Seoul followed by a shocking bout of jetlag in Phoenix (Thursday in Seoul and Monday in Phoenix via a weekend in Coventry is not to be recommended) are my only excuses. […]

Monitoring Small Aircraft 2
on May 18, 2017

  Background In January 2015 I wrote a short blog entitled “Monitoring Small Aircraft”. It described how we can monitor relatively small aircraft when they are equipped with modern digital avionics. Specifically (and please don’t interpret this as advertising) the Garmin G1000 system, which includes a data card facility for recording flight data. The original […]

Following the Taxiways
on April 21, 2017

In this blog I will explain how we compute the ground track for visualisations and why this is undergoing a process of revision. What the User Sees When we process flight data we often show the flight on a chart or, most commonly these days, on Google Earth. It is easy to see where the […]

What is the Groundspeed?
on March 15, 2017

  Recently a customer asked whether the groundspeed recorded by the flight data recorder was right. They had (allegedly) exceeded a taxi speed limit by a large margin and suggested, very politely, that we had got this wrong. This prompted me to do some checks and as the results were interesting I thought I would […]

Why Two Vertical Speeds?
on February 20, 2017

Following on from last week’s blog about rates of change, it occurred to me that I should have mentioned the second computed vertical speed and explained why we have two measurements for the same thing. After all, surely the vertical speed is exactly that. Why have “Vertical Speed” and also “Vertical Speed Inertial”? Quick Look […]

Rates of Change
on February 13, 2017

One of our analysts asked if I had written a blog about how we calculate vertical speed, and I said “of course I did, ages ago”. There followed a 15-minute hunt for the subject and eventually I had to admit that it was missing, so here goes with a quick blog to plug a gap […]
