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.

Automating Flight Data Conversion
Dave Jesse By Dave Jesse on August 22, 2018

I have been working on TCAS monitoring recently, and I’ll tell you more about that in future blogs, however in the middle of this work a friend asked why we didn’t just automate the processing of flight data. On the same day I sorted out one confusing data format, and, by putting the two together, […]

Monitoring TCAS Traffic Advisory Alerts
Dave Jesse By Dave Jesse on August 2, 2018

A quick recap for those unfamiliar with TCAS. The Traffic alert and Collision Avoidance System (TCAS II) helps to protect aircraft from hitting each other, so is a Good Thing. Please don’t ask me what happened to TCAS I or the differences between versions 6.04a and 7.1 etc. I’m not a TCAS expert. If you […]

How High is the Deck?
Dave Jesse By Dave Jesse on July 5, 2018

Customers who land helicopters on oil rigs need to know how high they are on the approach with respect to the deck height, and not with respect to the water. Of course, during the approach they are over the sea and the radio altimeter gives good readings for the sea and, as all good mariners […]

A crisis of confidence (intervals)
Charles Newey By Charles Newey on June 14, 2018

Lately I’ve taken to exploring some of the aggregated event statistics that we have on file at Flight Data Services — and as a side project, I was using my knowledge of statistics to develop a fairly straightforward anomaly detection algorithm. My first approach was to compute the daily average of a particular key point […]

Traffic Collision Avoidance System (TCAS)
Dave Jesse By Dave Jesse on June 6, 2018

The TCAS system is designed to avoid traffic collisions between two aircraft. At first a Traffic Advisory (TA) warning is given to alert the crews of approaching aircraft. Then, if the separation continues to reduce the two aircraft exchange position, direction and speed information and, in a clever piece of negotiation, agree which aircraft needs […]

When is a Hard Landing Not a Hard Landing?
Dave Jesse By Dave Jesse on May 1, 2018

The Simple Question It’s a simple question, and for today’s ditty I am only going to consider aircraft where the maintenance manual limitation is expressed in normal acceleration units (g). There are a number of aircraft (Embraer types and BAE 146 for example) which express hard landing criteria in vertical speed at touchdown, and this […]
